The 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 M996 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.
Design details Unlike the first generation Beretta 92M9
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. 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 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. The standard slide catch can be replaced with a
slimmer version to avoid snagging when the weapon is drawn quickly from a
holster. Models
The Px4 is available in four models: Type F: Single and double-action.
Decocker. Manual safety. Type C: So-called to be
Single-action-only. 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.
Px4 Subcompact The Px4 Storm Subcompact is a compact
Px4 chambered in 9×19mm and .40 S&W. It has a DA/SA trigger. The Px4 Subcompact
uses a tilt barrel system. It is intended for personal defense and law
enforcement use with a focus on concealed carry.
Beretta is marketing the Px4 Subcompact as the most advanced subcompact sidearm
in existence. It is lightweight and small. The barrel is stainless steel, to
help prevent corrosion from perspiration. The magazine release
button is both changeable and reversible. Finally, Beretta’s patented
SnapGrip Magazine Extender extends the grip size down for a more secure grip.
A high magazine capacity is available, along with a magazine adapter to extend
the grip to accommodate the full size magazine increasing capacity to 17 or 20
rounds in 9 mm and 14 or 17 rounds in .40 S&W. The Beretta Px4 Sub Compact
Magazine Adapter adapts the full size Px4 magazine for use in Px4 Sub-compact
pistol. Px4 Compact
The Px4 Storm Compact is sized between the Full Size and the Subcompact models.
It adopts the rotating barrel design of the full size pistols, but with a
shorter and proportioned slide and grip. This model also introduces an
ambidextrous slide stop lever. A high magazine capacity is maintained, with 15
rounds in 9 mm and 12 rounds in .40 S&W. The Px4 Storm Compact models accept the
full size magazines as well, increasing capacity to 17 or 20 rounds in 9 mm and
14 or 17 rounds in .40 S&W. Joint Combat Pistol
The Px4 is available in .45 ACP designated as the Px4 Storm SD. Notable
differences between the standard .45 ACP and the Special Duty are the desert tan
frame color, PVD coated magazines and internal firing control assembly, double
recoil spring, specially roll marked slide and a longer barrel to facilitate
the use of a suppressor. The PVD coated magazines are not scheduled to be
imported and there will only be one production run of the Px4SD. Supplies
are limited. Initial photos show the barrel with a silver proprietary coating
but the production models have a black finished barrel. Also, pistol tags
indicate that superluminova sight paint is standard but Beretta USA discontinued
use of the paint in 2009 so the Px4SD will have standard white 3-dot sights.
The special Pelican case contains oil, cleaning kit, three magazines, pistol,
all three back straps, all three magazine buttons, manual, warranty card
and two foam dividers. Prices for this pistol are ranging from
$750 to $1200 new. Project Allegiance
Announced in late 2007, Project Allegiance has Beretta USA paying a
$10,000 death benefit for any law enforcement officer who participates in
the program. "Participate" means purchasing a Px4, and registering with
the program. It is good for three years after the purchase. Beretta is also
offering free counseling, legal, and financial advice to the survivors of the
officer who is killed in the line of duty as part of the program.
