Beretta Px4 Storm" is a semi-automatic pistol manufactured by Beretta
of Italy and intended for personal defense and law enforcement use. The
Px4 uses the same short-recoil, rotating barrel action as the Beretta
8000 Models and uses the same trigger and safety system as the M9/92/96
series, while being completely different in design from either.
Light-weight polymer construction with steel inserts, a modular trigger
group, fully enclosing slide, Picatinny rail, and changeable backstrap
options for the grip are a radical departure from previous Beretta
designs.Unlike the first generation Beretta 92/96/M9 series, the Px4's
trigger guard is rounded for better concealed carry. The takedown pin of
earlier models is replaced by a spring-loaded bar, accessed via frame
recesses on both sides, which must be grasped and pulled down
simultaneously to release the slide. The slide spring is doubly captive,
being inserted approximately an inch into the transfer block at one end
and a receiving hole in the front of the slide at the other. The Storm
takes cartridges 9x19mm Parabellum, .40 S&W and .45 ACP. It is a
self-contained assembly, completely captured by the polymer guide. The
magazine holds the top round directly behind the barrel's breech end so
only a slight feed ramp is needed. This allows the barrel to fully
support the case. The 6-R rifling of the barrel generates
counter-clockwise torque which is harnessed by the locking system to
reduce the amount of pressure required from the rotating barrel lock's
cam and pin system to effect unlocking. The steel transfer block's cam
pin is 5 mm wide and 2 mm deep. The entire hammer unit mechanism can be
removed from the Px4, without the use of special tools, as a single
group. This allows easy access to the firing mechanism for cleaning. The
Px4's design makes it impossible to assemble incorrectly from a
field-stripped takedown. The Px4 features an interchangeable,
luminescent 3-dot sight system (coated in Super-LumiNova) for use in
dark or low-light situations. With short exposure to any kind of light,
the night sights' luminescence lasts up to 30 minutes. The weapon also
incorporates a Picatinny rail under the muzzle to allow flashlights,
laser sights, and other accessories to be attached. Beretta discontinued
the luminescent 3-dot nights sights for the Px4 in 2010, replacing them
with standard 3-dot sights. Removable and interchangeable parts To
aid the versatility of the Px4, a number of parts were designed to be
removable and interchangeable. These parts include the backstrap, the
magazine release button, the slide catch and the hammer unit mechanism.
The backstrap is available in three sizes: slim, standard and oversized.
The magazine release button can be mounted on either side of the weapon
and replaced by one of three types: standard, large or combat
(extended). The standard slide catch can be replaced with a slimmer
version to avoid snagging when the weapon is drawn quickly from a
holster.The Px4 is available in four models: Type F: Single and
double-action. Decocker. Manual safety. Type C: Single-action-only
("Constant Action"). Spurless hammer. No decocker. No safety. Type
D: Double-action-only. Spurless hammer. No decocker. No safety. Type G:
Single and double-action. Decocker. No manual safety.

Оружие самообороны Timeline Photos --The
Slingshot-- shanghai, flip, bean shooter, wrist rocket, vag badge, or
catapult (primarily British English) is a small hand-powered projectile
weapon. The classic form consists of a Y-shaped frame held in the off
hand, with two rubber strips attached to the uprights. The other ends of
the strips lead back to a pocket which holds the projectile. The pocket
is grasped by the dominant hand and drawn back to the desired extent to
provide power for the projectile (up to a full span of the arms with
sufficiently long bands). Slingshots depend on strong elastic materials,
typically vulcanized natural rubber or the equivalent, and thus date
back no further than the invention of vulcanized rubber by Charles
Goodyear in 1839 (patented in 1844). By 1860, this "new engine" had
already established a reputation for juvenile use in vandalism, as well
as at least one human death.
Оружие самообороны Timeline Photos Muzzle
brakes and recoil compensators are devices that are fitted to the
muzzle of a firearm or cannon to redirect propellant gases with the
effect of countering both recoil of the gun and unwanted rising of the
barrel during rapid fire. Muzzle brakes are useful for combat and timed
competition shooting, and are commonly found on rifles firing large
cartridges (such as big-game rifles), as well as some artillery and tank
guns. They are also used on pistols for practical pistol competitions,
and are usually called compensators in this context.
