Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application claims the benefit of U.S. Provisional
Patent Application No. 62/708,558 filed on Dec. 13, 2017, entitled
"Brace for handgun support", and also claims the benefit of U.S.
Provisional Patent Application No. 62/712,397 filed on Jul. 31,
2018, entitled "Modular Forearm Brace Mounting System(s) for
Handguns", which are hereby incorporated by reference in its
entirety for all that is taught and disclosed therein.
FIELD OF THE INVENTION
[0002] The present invention relates to a Modular Forearm Brace
Mounting System for Handguns.
BACKGROUND OF THE INVENTION
[0003] Forearm and or Upper Arm Brace are similar in concept to
those marketed & utilized for AR-15's, AK-47's, and other
similar large frame rifles redesigned to meet the requirements of a
handgun.
[0004] They are designed to be nearly universal or custom fit for
different gun designs or manufacturer's grip angles, double or
single column, revolver, single shot or semi-automatic, etc.
[0005] The device is utilized to provide more accurate shot
placement and allow persons that are weaker, disabled, or utilizing
heavier handguns to assist in supporting the weight, redistributing
recoil forces, and shooting more accurately.
[0006] In this document the terms "Pistol" and "Handgun" will be
used interchangeably and both are intended to refer to either
Revolvers, Single Shots, or Semi-Automatics.
[0007] This entire System of Sub-Systems was developed to aid
disabled users and users with diminished abilities to be able to,
or to continue to be able to, fire a handgun. The design intent of
the Brace Mounting System is to facilitate one handed firing of
both normal and large frame handguns (for example a 1911 or a Glock
for a "Normal" handgun and a Desert Eagle or a Ruger Blackhawk
Hunter for a "Large Handgun"). The Brace Mounting System is
intended to assist: those with limited or reduced mobility and
strength, those just starting in the pursuit of the shooting sports
that are not yet conditioned to the weight and recoil of handguns,
and those wishing to reduce recoil and/or increase the accuracy
potential of their shooting. Mounting the Forearm Brace of the
Brace Mounting System onto the user's forearm distributes the
weight of the weapon evenly and provides additional support to the
user, all the while being operated and held with a single hand.
Further the system assists by re-distributing the recoil produced
by firing a handgun, and creates more surface area for contact
reducing movement.
[0008] Very simply put, this device was developed to attach a brace
to a handgun and to fit the brace onto the user's forearm. It is
designed to fit normal to large sized handguns. Our system can
utilize both existing braces currently sold by others and braces
that we have designed ourselves. We have developed the
means/mechanisms to attach these braces to handguns such as 1911s,
Glocks, Large and small frame revolvers, Sig Model 320's, Barretta
92's, etc., etc. We also have developed a "universal model"
designed to fit most any semiautomatic handgun from a single stack
.22 to a double stack .45 apc.
[0009] Less than a month after placing the provisional patent the
inventor had a mishap, he slipped in the shower and put his
wrist/hand thru the glass shower door (the old-fashioned glass that
shatters). He suffered multiple cut/damaged tendons and cut a
nerve. He continues to suffer the effects of the injury and due to
the lingering effects, cannot tolerate the recoil associated with
firing handguns.
[0010] In the June 2018 Issue of the American Rifleman Mark A.
Keefe I V (Editor in Chief) wrote "there is another group that is
growing every day, and that is the aging armed citizen. NRA's Dr.
Joe Logar, national manager of the Adaptive Shooting Program, gave
a jam-packed presentation at the NRA Carry Guard Expo last year on
that very subject, and I think he is really onto something. A large
percentage of our population--an estimated 21 million
Americans--suffers from arthritis, and that means they sometimes
are no longer able to do things with their hands that previously
would have been a cinch. Too, there are other users looking for a
pistol solution, as described by NRA's Adaptive Shooting Program:
"According to the most current census data, there are approximately
74 million individuals that identify as disabled. This population
is growing as the Baby Boomer generation ages and as injured
soldiers return from overseas."
[0011] The limitations of the prior art are addressed by providing
an arm brace for a pistol having removable grip panels. The arm
brace with removable grip panels comprises a grip portion defining
apertures for connecting to a pistol frame as a replacement grip.
The arm brace further comprises a frame extending rearward from a
lower end of the grip portion. Further, a concave wrist support
element connected to the frame and configured to receive a user's
wrist while the user's hand associated with the wrist is gripping
the pistol.

without additional brace mechanism installed on the Brace Chassis.
The Brace Chassis is also designed and intended for use as a
Stabilizing Brace without additional Brace components. The Bare
Buffer Tube is designed and intended to be utilized as a Brace by
itself. Any combo of Brace, Brace Chassis, Bare Buffer Tube and
straps is envisioned.
[0058] FIG. 4 is a fully Assembled Right-hand View, Fully Extended
with Cup Brace Installed for Right Handed Users. Shown fully
assembled with Brace Chassis in the fully extended position, and
with the Brace mounted on the right-hand side (for Right handed
users) and in the most extended position.
[0059] FIG. 5 is a fully Assembled Right-hand View, Collapsed, with
Cup Brace installed for Right Handed Users
[0060] Shown fully assembled with Brace Chassis in the collapsed
position, and with the Brace mounted on the right-hand side (for
Right handed users) and in the bottommost or most collapsed
position.
[0061] FIG. 6 is a Left-hand View broken into the Main
Sub-Assemblies (Front Sub Assembly and Rear Sub Assembly). Shows
the Modular System in its 2 major Sub-Assemblies (Front and Rear)
separated.
[0062] Note 1: The Takedown Pin is shown, but it is not in its
normally installed position (in the AR-Lower). Brace is installed
in on the Left-hand side (for Left handed users) and in the
Centermost of 5 positions.
[0063] Note 2: For left handed users the opposite Grip Panel would
be utilized (Grip Panel on the Right-hand side of the gun).
[0064] The concept of operation is that the Sub-Assemblies can be
separated, and a different Front Sub Assembly for another pistol of
the same or a different type (for example, but not limited to, a
Beretta M-9/92, or a SIG 320, or a Glock) installed into the Rear
Sub-Assembly. Or a different Rear Sub-Assembly can be installed on
the same or different Front Sub-Assembly.
[0065] Note 3: The different types of pistols will utilize
different mounting systems. All mounting systems may or may not
include straps or other mechanisms to further secure the handgun to
the various Grip Connection Points (see more in other Figures).
[0066] Note 4: Upon mating the AR Upper and Lower Remnants together
the Tube will be inserted into the ID of the Buffer Tube. This will
prevent rotation around the Takedown Pin and add rigidity to the
system.
[0067] Note 5: Future versions may incorporate the means and
methods to temporarily adjust the Buffer Tube Liner to allow
folding of the device, and unfolding with the Buffer Tube Liner
"locking" back into its normal position (manually or
automatically).
[0068] Note 6: All dimensions and layout may vary to reduce length,
increase ergonomics, or for other reasons including custom
diameters or lengths that are proprietary

included. Utilization of Rear Receiver Plate for other purposes
also reserved.
[0079] FIG. 12 shows Brace Chassis Lower/Rear View, with Optional
Cup Brace Installed and with Optional Strap(s) installed. Note this
specific Strap is depicted only for clarity. Note second
penetration (to the left of the current strap and to the left of
the swell for the detent pin of the brace Chassis) for an
additional optional strap.
[0080] Note 1: Straps may or may not have attachments (for example
a ring of metal similar to a key chain ring (materials shape and
size may vary) to aid users to grab the strap to ease manipulation
of the straps. Means for tightening and retaining the position of
the strap(s) may vary. The use of the straps to hold or retain
devices when in use or not in use are retained. May include
fittings to allow the straps to be tightened one-handed (one piece
of hardware would be a ring to allow the strap to go thru the ring
then to double back on itself for tightening purposes and then
secured in place).
[0081] Note 2: The Buffer tube may be replaced with a Pistol type
buffer to support the acceptance of different buffer tube style
braces. Pistol type Buffer Tubes can be seen depicted in several of
the Figures in this document, either currently made or made in the
future.
[0082] Note 3: All braces intended and designed to be utilized with
or without straps to further secure to the user's forearm.
[0083] Note 4: All Braces may either mount on a buffer tube (Buffer
Tube with or without a channel (either an internal channel or an
external channel), or indentations or built up areas), or directly
to a Tube.
[0084] Note 5: The Brace Chassis without an additional Brace
attached to it is also intended to be a Brace with or without
straps.
[0085] Note 6: The Buffer Tube without an additional Brace Chassis
and/or Brace attached to it is also intended to be a Brace with or
without straps.
[0086] Note 7: Round Buffer tubes may have flats or indentations or
built up areas cut into them for the L, Tee, and Pulling Elbow
braces (not limited to these braces) to more securely mount the set
screw or other device for mounting onto the round pistol buffers
(flat surfaces for the set screws to snug against--rather than a
flat bottom set screw setting against a round surface).
[0087] Note 8: All can be utilized in any configuration around the
buffer tube (aligned anywhere around the clock from the 12 O'clock
position completely 360 degrees back to the 12 o'clock.
[0088] Note 9: Photo depicts Brace Chassis with JB weld utilized to
fill all "channels" and to attach the rear portion of the Brace
Chassis to its main body. This will be all part of a final molded
or cast product (with or without the use of JB weld). All Channels
may or may not be filled. JB Weld is also utilized for more thread
surface for the Brace Screws. Surface(s) for attachment of Braces
may extend beyond the current body of the Brace Chassis. Additional
screws, other fittings, and location of screws or other fittings
may be changed.
[0089] Note 10: Some models have slots cut in the body of the Brace
Chassis immediately below the Swell for the Buffer Tube area and
immediately in front of, behind (or both) the swelled area for the
Pin that locks the Brace Chassis into position on the Buffer Tube
indentations for position adjustment. The location and quantity of
these mounting locations for Straps, slings, or supporting
mechanisms may change. May utilize different length, width, weight
and types of straps and mounting and removing hardware. Width is
currently limited by the space available fore and aft of the Pin
area of the Brace Chassis.
[0090] Brace is molded to fit the "average forearm." It has three
sets of 2 holes. Future models may have fewer holes, more holes, or
be completely absent of holes. Holes are reinforced with metallic
fittings. Metallic fittings may be replaced with built up portions
of the brace itself or fittings constructed of other materials.
Brace may be constructed of other Thermoplastics, polymers, metals,
or other materials. Brace may or may not include slots, metal or
polymer fittings, or external portions of the molding to support
the addition of straps to further secure the Cup Brace to the
user's forearm. The assembly may or may not utilize the brace.
Dimensions are not fixed and length, width or thickness may vary.
The brace may utilize spacers or fittings between the Brace and The
Brace Chassis. The Brae may include a rear portion or a front
portion. Portion of brace may be utilized for mounting of
accessories. The Brace may mount around a Pistol type Buffer Tube
via a sleeve or other mechanism.
[0091] Note 11: May incorporate a removable and washable (laundry
or hand washable) "sleeve" or "sock" to aid user comfort and to
allow distance between sensitive parts of the user's skin and the
Brace. Currently envisioned as a fleece material with "ears" or
"pockets" on both end that will go over the top and bottom surfaces
of the brace and be connected between the 2 ears with a solid piece
of material (between the brace and the user--may incorporate
elastic to help retain on the brace. May incorporate a separate or
additional piece of material for keeping the straps from coming
into direct contact with the user's forearm. Colors and
construction may vary as well as the types of material
utilized.

(other connection may be kept in the future and plugged or left
open). Removable cover may be located either on the rear, side(s),
top, bottom, front, or Buffer Tube mounting area. May utilize other
fittings or devices for tool-free removal of cover, or a shaped cap
that can be secured and removed without tools. Brace, cover, and
fittings can be constructed of metals, polymer, rubbers or other
materials. Brace may be attached to a Buffer Tube or other shaped
length via threads, by mechanical tightening around the buffer
tube, welding (or other means of adherence such as chemical bonding
agents), mechanical means including, but not limited to, set
screws. Designs may or may not include ergonomic changes or changes
in physical dimensions. Brace may be aligned in either a "Brace

angles other than a hard 90-degree Tees. Tee may or may not include
a short length of tube (in the open ends) for appearance and/or
more surface area contact. The short length may or may not include
the means for storage inside one or both tubes connected to the
Elbow. May utilize other fittings or devices for tool-free removal
of cover, or a shaped cap that can be secured and removed without
tools. Brace, cover, and fittings can be constructed of metals,
polymer, rubbers or other materials. Brace may be attached to a
Buffer Tube or other shaped length via threads, by mechanical
tightening around the buffer tube, welding (or other means of
adherence such as chemical bonding agents), mechanical means
including, but not limited to, set screws. Designs may or may not
include ergonomic changes or changes in physical dimensions.
[0100] Note 1: Note Ergonomic improvements may or may not be
included.
[0101] FIG. 17 is a Right-Hand View of Sliding Brace in Collapsed
Position utilizing an Elbow Brace in this Photo (but intended for
any type brace). Sliding brace to include both inner tubes to be
smaller than outer tube, and outer tube to be smaller than inner
tube. May include more than 2 tube lengths. May incorporate
mechanisms to lock or fix in open/extended position, collapsed
position, and intermediate positions between fully expanded and
fully collapsed. Materials may be metal, polymer, or other. Designs
may be for a sliding Buffer tube.
[0102] FIG. 18 is a Drawing of Left-Hand View of Unmodified M-4
Stock in Preparation to become a Modified Brace Chassis, and an
Unmodified Buffer Tube.
[0103] FIG. 18: Unmodified M-4 Stock and Full-Sized Buffer Tube.
Note White outline of Buffer Tube (same as orange colored buffer
tube in drawing. Note red line for a proposed cut location). Black
Dashed lines represent Brace Chassis cuts for currently constructed
Brace Chassis.
[0104] This model is similar to the Brace Chassis and Buffer Tube
seen in FIG. 1. The main differences are that this Buffer Tube may
be significantly shortened and the Brace Chassis has different
dimensions (it is larger). The purpose of these changes is for
aesthetic and support--to ensure that the Buffer Tube does not
extend past the rear-most portion of the Brace Chassis when the
Brace Chassis is in the collapsed position. This model will also
facilitate the use of wider and or heavier straps for securing to
the user's forearm.
[0105] FIG. 19 is a Drawing of Left-Hand View of Unmodified M-4
Stock in Preparation to become a Modified Brace Chassis, and a
modified Buffer Tube. The Pen Depicts a Point of Modification to
the Stock (soon to be Brace).
[0106] Note 1: Pen Depict one possible cut point.
[0107] Note 2: Buffer Tube (white template) has been folded down to
one potential new length.
[0108] FIG. 20: Drawing of Left-Hand View of Modified Brace Chassis
(formerly an Unmodified M-4 Stock) and a Modified Buffer Tube
(shortened), Shown in the Fully Extended Position
[0109] FIG. 21 is a Drawing of Left-Hand View of Modified Brace
Chassis (formerly an Unmodified M-4 Stock) and a Modified Buffer
Tube (shortened), Shown in the Collapsed Position.
[0110] FIG. 21 depicts rear of stock removed to create Modified
Brace Chassis. Depicted both in the extended and the collapsed
positions.
[0111] Note 1: Shorter Buffer Tube and fold in paper depicts end of
Modified Brace Chassis.
[0112] Note 2: Locations for cuts of Buffer tube and Brace Chassis
may be changed for overall length, ergonomics, aesthesis, or
operation, or other design basis. Other components may be shortened
to allow more adjustment in length and still maintain the same
overall length from the trigger to the rear-most portion.
[0113] FIG. 22 is a Drawing of Left-Hand View of Modified Brace
Chassis (formerly an Unmodified M-4 Stock) and a Modified Buffer
Tube (shortened), Shown in the Collapsed Position. Brace Chassis
has been shortened from both the Front and the Rear.
[0114] FIG. 22 shows rear of stock removed and Front of stock
removed to create another version of the Modified Brace Chassis.
Depicted only in the fully collapsed position.
[0115] Note 1: Shorter Buffer Tube.
[0116] Note 2: Locations for cuts of Buffer tube and Brace Chassis
may be changed for overall length, ergonomics, aesthesis, or
operation, or other design basis. Other components may be shortened
to allow more adjustment in length and still maintain the same
overall length from the trigger guard to the rear-most portion.
[0117] FIGS. 23-27 relate to Grip Connection Points.
[0118] Grip Panel Type mounts--Mount via removable Grip Panels.
Entire replaceable grip for use with handguns similar to Dan Wesson
Revolvers, T. C. Contenders, Ruger Blackhawks, 1911, Beretta M9,
Desert Eagles, etc. Also includes guns with removable grip inserts
(for example Gen 4 Glocks, S&W M&P version 2,
Springfield's, etc.
[0119] An alternative to the Grip Panel Type mounts would be a
"Main Spring Housing/Rod". This would come directly under the
user's forearm (or may utilize an offset to run along the
bottom-side of the user's forearm (in a similar location to the
Grip/Rod models).
[0120] Slug-Plug type mounts--Mount via holes/voids in the Grip
(typically referred to as a "Slug Plug Hole" or "Lanyard
Hole").
[0121] Universal type mounts--Intended to fit most handguns
(revolver, single shot or Semiautomatic) from Single stack .22's to
double stack .45's. May utilize a single or double (opposing)
shaped angle bar shaped components (not limited to geometry).
Universal type mounts may also utilize a single shaped unit
intended to flex on the sides to fit various widths, or this type
may be custom shaped to fit specific handguns.
[0122] Non-serialized frames with integral Rods built into the
frame. Guns such as the Sig 320, Honor Guard and others where the
serial number is not on the traditional "Frame". Replacement frames
can be purchased as a part rather than a firearm. These replacement
(or original from the factory) frames will come either with the Rod
directly attached or the means to attach a rod to the frame
installed in the grip or other portion of the replacement grip
module.
[0123] Serialized frames with integral Rod or integrated into the
design for removable Rods built into the frame.
[0124] Custom molded sleeves that grips fit into, or mates next to
the pistol. For example, remove the rubberized grip from a Ruger
SR-22. Reinstall a new grip (constructed of various materials
including but not limited to metals, polymers, rubbers, etc.) with
either the Rod permanently attached or the means to attach a Rod to
the grip with e Rod being removable.
[0125] All types can utilize straps, mechanical fasteners or other
means for mounting to or mating next to the pistol.
[0126] Note: All Braces may utilize an offset in the Rod to allow
the Rod and Buffer Tube to run at the 6 O'clock position (or other
positions) directly below the center of the users forearm to
utilize Brace types that mounts vertically over and/or around the
user's forearm.
[0127] Note: Some Grip Connection Points may utilize a rod that
attaches directly to the bottom rear-center of the Grip area (for
example, but not limited to the Universal Types and the
Non-Serialized Frame types).
[0128] FIG. 23 shows a Grip Connection Point (for Right Handed
Users) for a Single Action or Double Action Revolver Type Handgun.
Shown with Bare Rod Pull Pin and Tube. Note this rod may or may not
be the same Outer Diameter as a Buffer Tube to facilitate the use
of these or any other Stabilizing Braces (even those manufactured
by others). Note use of pull pin.
[0129] FIG. 24: Grip Connection Point (for Right Handed Users) for
a Barretta M9/92 Type Handgun. Shown with Bare Rod (Rod not drilled
for Pull Pin) Pull Pin and Tube.
[0130] FIG. 25: Grip Connection Point (Universal for handedness)
Slug Plug Type for a Glock or other Handgun that accepts a "Slug
Plug." Shown with Pull Pin and Tube. Note ability to install Pull
Pin from right hand side or left-hand side. Retain the ability to
put pull pin in any orientation.
[0131] Note 1: This photo and multiple photos depict an alternate
Brace System that will be discussed further (it is a Tube type
Brace System)
[0132] FIG. 26: Grip Connection Point (universal for handiness or
Right or Left Handed) for a Non-Serialized Frame Type Handgun,
shown with Bare Rod. Note: Electrical tape is wrapped around the
rod in an attempt to represent it as the same material and molded
in one piece. Material of Grip and Rod may vary.
[0133] Modular and/or Replaceable Grips and Non-Serialized Grip
"non-Frames". The entire brace grip etc. is replaceable for guns
like Sig P320, Ruger American, Honor Guard, etc. with replaceable
lowers.
[0134] FIG. 26--Non-Serialized Frame. Rod will be an integral part
of the Frame, or the frame will be manufactured to accept the
insertion and removal of the Rod. Rod can be either Centered at the
rear-bottom-center of the grip or at either rear-bottom side (sides
to suit Left-handed or Right-handed users).
[0135] FIG. 27 shows a side view of a Grip Connection Universal "U"
Shaped (universal for handiness or Right or Left Handed). Note: Rod
Depicted may or may not be in this orientation.
[0136] The Universal U shaped is intended to be constructed of
Polymer (but may be constructed of another material) may be rigid
or with a "memory" or insert to cause it to seek the smaller shape
and allow it to accept larger guns. Sides to be flexible and hug to
the sides of the pistol with or without a strap to further secure
the handgun to the Grip Connection Point. This flexing will allow
it to fit more types of handguns). Rod can be either Centered at
the rear-bottom-center of the grip or at either rear-bottom side
(sides to suit Left-handed or Right-handed users).
[0137] FIG. 28 shows a Grip Connection Grip Sleeve Model (universal
for handiness or Right or Left Handed). The Grip and Rod Removed
from Handgun Frame, shown with Bare Rod. A custom molded sleeve is
illustrated that grips fit into, or mates next to the pistol. For
example, remove the rubberized grip from a Ruger SR-22. Reinstall a
new grip (constructed of various materials including but not
limited to metals, polymers, rubbers, etc.) with either the Rod
attached or the means to attach a Rod to the grip built into the
grip. Depicted with Grip removed and installed. Rod can be either
Centered at the rear-bottom-center of the grip or at either
rear-bottom side (sides to suit Left-handed or right-handed
users).
[0138] FIG. 29 illustrates a Hybrid Brace System (Note Tube on the
handgun side of the AR Lower Remnant).
[0139] FIG. 29 is a Hybrid between the Tube Type Brace System and
the Standard Buffer Tube Type Brace System. The Biggest difference
between the Buffer Tube Type Brace system is--This does not utilize
the Remnant of an AR Upper, and does not utilize the Buffer Tube
Liner. This system utilizes a Short Tube (to be welded to the AR
Lower Remnant) and Drilled for a Pull Pin that will lock the Rod to
the Tube.
[0140] This Brace system is cross compatible with the Tube Type
Brace System
[0141] This Brace System consists of: [0142] The Grip Connection
Points (can utilize all Grip Connection Point types) include Grip
and Rod. The Rod associated with the Grip Connection Points is
drilled for insertion of a 1/4'' Pull Pin (size may vary). Very
Similar to Grip/Rod [0143] Tube--O.D matches the OD of a standard
Buffer Tube O.D. The ID of the tube is roughly 3/4'' (for insertion
of the Rod). This is accomplished with a shot length of Tube within
tube for this example (may be one piece). The Tube is also drilled
to accepts a 1/4'' Pull Pin. [0144] Pull Pin--A pull pin that can
be inserted thru the Tube and the Rod to lock them together. This
Tube allow the changeout between Different pistols with different
Grip Connection Points or to changeout different Tubes and Braces.
The Pull Pin is such that is locks into place and only allows
release if the push button is utilized. Different Pins, mechanical
fatteners, or threaded/quick connections may also be utilized in
lieu of a Pull Pin. [0145] Pull Pin can be in any arrangement (not
just 3 O'clock to 9 O'clock). [0146] This Pull Pin is exactly the
same Pin as those utilized in the Hybrid Brace System. Braces--May
utilize any brace intended for a Standard Pistol Type buffer tube,
or proprietary types. [0147] All materials and sizes may be
changed. The Tube and Rods do not necessarily have to be round and
can utilize different geometries to aid alignment and or prevent
rotation.
[0148] FIGS. 30 and 31 relate to a Tube Type (also identified as)
Blood Stripe Line.
[0149] FIG. 30 shows a Blood Stripe Line.
[0150] The following components are shown starting at bottom left
and moving Clockwise:
[0151] Handgun (normal with no accessories mounted) [0152] Grip
Connection Point Double Angle Type with Rod and Optional Strap.
Note holes drilled in both the left hand and right-hand angles for
mounting of Rod. Holes allow for reversal for handedness (the
Rod/Bolt joint also acts as the Adjustment Joint). Wing Nut or
other Fastener for tightening and locking into position and
loosening to change position. [0153] Tube with installed Pull Pin,
and T Shaped Brace (with optional Strap installed). [0154] Bare
Unmodified T Shaped Brace without optional strap. [0155] Grip
Connection Point 1911 Type with hole drilled and Bolt installed.
Bolt is for mounting to a Rod. [0156] Shown in Center--Rod with
holes drilled for Connection Bolt to 1911 Type Grip Connection
Point (depicted in photo) (Grip type may change to another Grip
Type or Grip Connection Point), and for Pull Pin connection between
Rod and Tube.
[0157] FIG. 30--Utilizing an aluminum 1911 grip. The grip is
drilled thru and a threaded fitting (a nut (as is nuts and bolts),
but not limited to a nut) is adhered to the interior surface of the
handgun grip in a void created in the inside of the grip (against
the handgun frame). The Rod (solid Aluminum with OD of .75'') is
flattened (by milling stamping, etc.) or otherwise shaped on one
extreme end--so that it lays nicely against the 1911 grip. The rod
also has a hole drilled thru it in this flattened area
corresponding to the hole drilled thru the grip and aligning with
the nut inside the grip. The rod is attached to the grip via a
fastener (picture a pan head screw or bolt). The rod inserts into
the tube (OD of 1'' ID of .75''). The Rod is attached to the tube
either by welding, the insertion of a removable pull pin (requires
drilling of the Rod and tube), or other means. There are two
separate models of the Rod--one that allows forward rotation and
one that does not. Means for the rod to lock in the rearward
(normal firing position) or the forward or front/folded position
(for Storage and Transport) can be incorporated. The rod and tube
can also be shapes other than round to ensure proper alignment
(oval, with a channel in either component, square or other
geometry), and to assist to prevent rotation. Channels or other
mechanisms may also be utilized for alignment and anti-rotation
purposes, or other purposes. Brace is installed either directly
onto or into the tube or into a larger size tube or attached to a
buffer tube. Can adapt to the non-Blood Stripe Series. Removal of
the Bolt that adheres the grip to the Rod will allow normal
holstering of the Pistol. The opposite Grip Panel will also be
drilled and have a fitting (allowing to switch form right-handed to
left handed without additional changes other than placing the Rod
and associated fitting on the opposite side.
[0158] Also depicted is a universal type Grip but with holes
drilled in both the left hand- and right-hand angle bar for
mounting of the Rod. Fittings included to "Lock" the Rod at a
specific angle but allow adjustment to other angles.
[0159] Braces are adaptable for Left- and Right-hand use.
[0160] This series can also utilize any braces in the Non-Blood
Stripe series. Maximum effort has been put forth to ensure
cross-compatibility where ever possible.
[0161] Pull Pin construction, type, location and angle of
attachment may be changed. As well as the Type of fastener
used.
[0162] FIG. 31 shows the "Folded for Storage and Transport"
position.
[0163] FIG. 32 shows a C-Shaped Brace and Brace Mounting Sleeve
shown from the left-rear, it is adjustable for length.
[0164] Described from the Grip Connection Point going to the
user:
[0165] Grip Connection Point--1911 Type with Adjustable Joint/Bolt.
[0166] Rod (under Grey material, or Grip may be permanently
attached to Rod, or directly to the Tube, or Permanently to the
Tube via a Rod). [0167] Tube [0168] Pull Pin [0169] Brace Mounting
Sleeve--Able to ride up and down the length of the Tube, allowing
for adjustment to fit various users. With provisions to lock into
place at various positions along the Tube. Brace mounting Sleeve
and Tube OD may have different geometry and/or channels or other
physical means to prevent rotation and aid alignment. Include
provisions to allow sleeve to move and to be set and locked into
various positions down the length of the Tube. [0170] C Shaped
Brace--Mounted to the Brace Mounting Sleeve. This may be removable
or a permanent part of the Brace Mounting Sleeve. Note Fittings
between Brace and Sleeve. Fitting may vary. Location of the means
to set the position of the Brace Sleeve anywhere around or on the
Brace Locking Sleeve or Tube. [0171] May include combinations of
components from Buffer Type, Hybrid, or Tube Type. Sliding Brace
Chassis will have means for locking into various positions. Brace
may or may not include straps. Bare Tube is also designed to be a
Brace. Included provisions for Brace to switch from right-handed to
left handed. [0172] NOTE: Grey material at the Rod/Brace junction
should be ignored (other than to depict the ability to utilize
Grip/Rod Combinations from other parts of this document. [0173]
Tube and Grip may be an integral piece.

[0187] Benefits
[0188] The system has multiple and myriad benefits including, but
not limited to:
[0189] More Secure Attachment:
[0190] The system facilitates a more secure attachment between the
handgun and the user before, during and after the firing event.
[0191] Redistribution of Weight:
[0192] It assists to mitigate the weight of the handgun by
redistributing a portion of the weight to the forearm.
[0193] Redistribution of Recoil:
[0194] To mitigate the effects of recoil directly applied to the
hand by partially redistributing the recoil to the forearm.
[0195] More Accurate Shooting:
[0196] To increase accuracy of shots by increasing the contact area
with the body and reducing the effects of human physiology, in
particular eliminating the wrist's weakness and mobility.
[0197] Safety: [0198] More accurate shooting is inherently safer
and also when used for hunting more accurate shots are more humane.
[0199] Reduce and/or eliminate errant second shots with
semi-automatics (a true safety concern).
[0200] Intended Users
[0201] Those suffering from reduced strength or reduced ability to
withstand recoil.
[0202] Loss of digits (fingers and/or especially the thumb) or loss
of a portion of the palm (combat veterans, industrial accident, any
accident, or illness).
[0203] Those suffering from nerve pain/reduced feeling (nerve pain
induced as a result of the recoil impulse).
[0204] Reduced capacity to handle recoil due to injury or illness
(including Arthritis).
[0205] New users in training. This groups includes anyone new to
shooting sports be it very young age or new to the sport at any
age. The System assists with mitigating the violence of recoil, the
weight of the handgun, retention, and eliminating errant second
shots.
[0206] The effects of recoil are different on every person--The
local police department here in my area has to regularly fail
students out of their academy because they cannot become adjusted
to recoil.
[0207] You have not lived until you have been on the firing line
with a new user that drops a semi-automatic handgun after the first
shot--yes it does happen.
[0208] Aged users or any users suffering from disabilities
including but not limited to: arthritis, reduced or low strength,
etc.
[0209] The inventor personally knows users that have either
prematurely had to stop using their favored handguns (and move to
progressively smaller calibers) or have exited the shooting sports
entirely due to the effects of recoil as they age.
[0210] Large caliber handguns for hunters.
