Description
FIELD
[0001] The present invention relates generally to a structurally
integral replacement part system generally useful for improving the
performance and durability of previously known firearms, and in a
specific though non-limiting embodiment to a part system useful for
manufacturing and/or replacing certain parts of the 0.45 caliber
M1911 series semi-automatic pistol invented by John Browning, for
example, a Colt 1911 0.45 caliber pistol.
BACKGROUND
[0002] The basic Browning M1911 design has seen very little change
throughout its long production life. The basic principle of the
pistol is recoil operation. As expanding combustion gases force a
bullet down the barrel, they give reverse momentum to an associated
slide and barrel, which are locked together during this portion of
the firing cycle. After the bullet has left the barrel, the slide
and barrel continue rearward for a short distance.
[0003] At that point, a link pivots the barrel down and out of
locking recesses formed in the slide, thereby bringing the barrel
to a stop. As the slide continues rearward, a claw extractor pulls
the spent casing from the firing chamber and an ejector strikes the
rear of the case, thereby pivoting it out and away from the pistol.
The slide then stops and is propelled forward by a spring to strip
a fresh cartridge from the magazine and feed it into the firing
chamber. At the forward end of its travel distance, the slide locks
into the barrel and is ready to fire again.
[0004] Since its inception, the M1911 has lent itself to
customization, with replacement sights, grips, and other
aftermarket accessories being the most commonly offered replacement
parts. Since the 1950s and the rise of competitive pistol shooting,
many companies have been offering the M1911 as a base model for
subsequent customization. Typical modifications range from changing
the external finish, checkering the frame, and hand fitting custom
hammers, triggers and sears.
[0005] Other modifications include compensators and the addition of
accessories such as tactical lights and viewing scopes. A
relatively common modification of the original Browning design is a
full-length guide rod that runs the full length of the recoil
spring. This change adds weight to the front of the pistol, but
does not generally result in an increase in accuracy or
reliability, and generally make the pistol much more difficult to
disassemble.
[0006] Accordingly, there is need for modifications, replacement
parts, and a system to increase the durability and performance of
M1911 pistols.
SUMMARY
[0007] In an example embodiment of the present invention, an
improved M1911 pistol is provided, including: a frame; a slide; a
grip safety, a safety lock; a disconnector; a hammer; and a sear.
Each of the frame, the slide, the grip safety, the safety lock, the
disconnector, the hammer and the sear includes stainless steel. The
stainless steel may be a 17-4Ph metal.

DETAILED DESCRIPTION
[0072] In order to overcome various shortcomings identified in the
weapons found in the prior art, the present inventors have
developed a number of proposed alterations, substitutions and
replacement parts that improve the performance, efficiency and
durability of an M1911 pistol, without substantially increasing the
weight, cost or complexity of disassembly of the weapon.
[0073] For example, in one embodiment, an altered M1911 pistol
comprises a stainless steel casting; in one specific embodiment,
the stainless steel is a 17-4Ph metal. To date, this is believed to
be the only civilian version of the weapon so cast.
[0074] A clear advantage to this approach is that the resulting
weapon will better stand up to extreme conditions and battering.
For example, it has been found that 17-4Ph metal can be reduced to
approximately 150 degrees below surrounding ambient temperatures,
and then brought up to approximately 150 degrees above surrounding
ambient temperatures without incursion of molecular change within
the metal. A 17-4Ph metal is also the most rust resistant of the
stainless steels, and can sustain multiple hours of continuous salt
spray without suffering deleterious performance effects.
[0075] In one embodiment, annealing is done with a double solution
annealing process, thereby achieving a Rockwell hardness of
approximately 34-36 on the receiver and approximately 42-46 on the
slide. In contrast, the vast majority of handguns currently offered
for sale comprise a Rockwell hardness level of 26 or less.
[0076] In a recent performance, the inventors subjected multiple
test samples to both a drop test and a mallet test, each of which
are specifically designed to assess whether a firearm is likely
suspect to inadvertent firing or other forms of unintended
discharge. While there are several firearm industry-recognized
standards for drop tests, the inventors applied drop test
requirements adopted by the State of California because those
standards are amongst the strictest in the United States. A
twenty-four (24) ounce mallet was used for the mallet test. Each of
the subject samples passed both tests.
[0077] In many versions of the prior art, the plunger tube will
come loose during the firing process, thereby resulting in failure
of the weapon. This shortcoming is so pronounced that sometimes the
internal plunger spring will eject from the firearm with such force
that it cannot later be relocated.
[0078] To overcome this shortcoming, the inventors manufacture the
plunger tube as part of the frame itself; in other words, the
integral plunger tube is machined directly onto the frame, thereby
rendering it impossible to loosen or fall off the frame because it
is manufactured structurally integral therewith.
[0079] This same process is then repeated with the ejector, so that
there is no subsequent fitting or drilling stage. For a home
firearm builder, this eliminates several tedious steps in the
building process, as well as any concern regarding rail damage or a
roll pin sticking out into the frame rail due to improper
installation.
[0080] Most novice shooters, and even many experienced shooters,
have difficulty remembering to keep their trigger index finger out
of the trigger guard until it is time to shoot. The inventors
consider that a leading cause of this failure is the fact that in
all known prior art models there isn't any specific place the
trigger finger should necessarily rest. The weapon disclosed herein
therefore further comprises a "ready-one" finger position located
directly in front of the trigger guard and to the rear of the
tactical rail that will serve as a natural rest point and reminder
to the shooter to obey this basic firearm safety rule.
[0081] In another embodiment the weapon comprises an improved
"beavertail" shaped grip safety, so that when the shooter's hand
reaches its most optimum gripping position, a maximum hand/grip
relationship relative to the slide is achieved. This modification
confers greater control over the firearm, thereby resulting in a
quicker recovery time for subsequent shots, and a reduction in the
amount of recoil felt by the shooter.
[0082] Also, all of the sharp edges of the grip are reduced and
opened up relative to the trigger housing. Similarly, reducing
frame dimensions supports a better grip, and improves holstering
due to a reduction of drag imparted by the holster material.
[0083] In another embodiment, a flared magazine well is added, and
the stop within the magazine well is lowered, thereby allowing for
more brands of magazine to be accepted. This change also
facilitates a faster loading of the magazine.
[0084] In other embodiments, a tactical rail is installed just in
front of the trigger guard; in one specific though non-limiting
embodiment, the tactical rail comprises three slots instead of the
usual one slot offered by typical manufactures, thereby allowing a
greater variety of accessories to be added.
[0085] In further embodiments, an extended magazine release is
included, and in still further embodiments, a performance barrel,
bushing, link and pin are added, e.g. barrels, bushings, links and
pins offered by Storm Lake Match.RTM.. In further embodiments
still, a recoil reducer system is included, such as the Sprinco
Recoil Reducer.RTM., which substantially reduces the felt recoil,
thereby allowing for quicker recovery for the next shot.
[0086] In other embodiments, the pistol is equipped with an
extended slide stop and an extended thumb safety; in a presently
preferred embodiment, these parts also made from 17-4Ph stainless
steel, thereby allowing for the longest possible weapon life. In a
further embodiment, these parts are also melted for comfort and
fit, and reduced drag while replacing or drawing the weapon from a
holster.
[0087] In other embodiments the gun comes with a rear sight (e.g.,
area site from Ghost Ring.RTM.) and a fiber optic front sight. As
those of skill in the pertinent arts will attest, a Ghost Ring.RTM.
rear site will put the shooter on target with an ease not generally
experienced with other sight combinations.
[0088] In other embodiments, a commander-style hammer having a
round configuration for reducing the chance of the gun getting
caught on a garment or holster is also provided, and in still
further embodiments a lanyard ring attachment is disposed on a
lower portion of the main spring housing is to facilitate tethering
of the weapon to the shooter. In other embodiments, gripping
serrations disposed on both the front and rear of the slide allows
multiple ways to rack the slide.
[0089] Finally, the weapon is equipped with a smooth, crisp trigger
pull, so that additional (and oftentimes expensive) gunsmithing is
avoided. Exotic wood grips, such as Coco Bolo.RTM., are typically
installed, and optional grips for tactical use are made
available.
[0090] In one presently preferred embodiment, the resulting firearm
is then packaged and sold with two stainless steel eight-round
magazines, a cleaning brush, a custom metal barrel brushing wrench
tool, and a compilation of useful National Rifle Association safety
literature. In a further preferred embodiment, an associated gun
case used for storage and transportation is airline drop-test
approved, and equipped with a plurality of locking devices, for
example two padlocks, in order to secure the case to the
satisfaction of airport security.
[0091] Example embodiments of the present invention may be seen in
FIGS. 1 to 16D. As shown in FIGS. 1 to 3 and 6 to 9, embodiments of
the present invention include pistols 10 having improved frames 26,
which may be smaller in dimension than a frame being replaced. The
frames may be stainless steel and may be 17-4Ph stainless steel. A
ready finger position may be located in front of trigger guard
22.
[0092] Embodiments may include improved slides 12, which may be
stainless steel and in certain embodiments, 17-4Ph stainless steel.
See, e.g., FIGS. 1 to 2, and 4 to 5. Further embodiments may
include improved grip safety 18. See, e.g., FIGS. 1 to 2 and 12 to
12D. Embodiments may also include improved safety lock 14, hammer
16, plunger 20, grip attachment surface 24, disconnector 28, sear
30 and slide stop 32. Each of these features may be stainless steel
and in certain embodiments, 17-4Ph stainless steel.
[0093] The foregoing specification is provided only for
illustrative purposes, and is not intended to describe all possible
aspects of the present invention. While the invention has herein
been shown and described in detail with respect to several
exemplary embodiments, those of ordinary skill in the art will
appreciate that minor changes to the description, and various other
modifications, omissions and additions may also be made without
departing from the spirit or scope thereof.
