About this product
The Beretta PX4 Storm Full-Size Pistol is a duty-ready semi-auto handgun built around a rotating-barrel locked-breech system that cuts felt recoil and keeps the muzzle flat.

Whether you’re a first-time buyer or a seasoned shooter, this beretta px4 storm full-size pistol gives you proven Italian engineering at a price that won’t break the bank.

Key Features
- Rotating-Barrel Locked-Breech System: Why it matters — this Beretta-exclusive design reduces felt recoil by about 30% compared to a traditional tilting-barrel pistol, so you stay on target faster.
- Interchangeable Backstraps: Why it matters — three different grip inserts let you tailor the circumference to your hand size, giving you a natural point of aim without buying a custom frame.
- Ambidextrous Slide Stop & Magazine Release: Why it matters — lefties and righties can operate the controls without breaking their grip, making it a true defensive pistol for any shooter.
- Integral Picatinny Rail: Why it matters — mount a weapon light or laser directly to the dust cover without aftermarket adapters, keeping your setup low-profile and secure.
- Serrated Slide with Bruniton® Finish: Why it matters — the aggressive serrations give you a sure grip when racking the slide under stress, and the corrosion-resistant coating holds up to sweat and humidity.
Who It’s For
This full-size pistol is for the home defender who wants a soft-shooting, reliable sidearm that fits a wide range of hand sizes. It’s also a solid choice for new gun owners because the low bore axis and rotating barrel make it easier to shoot accurately right out of the box. If you’re comparing the beretta px4 storm compact vs full size, the full-size gives you a longer sight radius and higher magazine capacity — 17 rounds in 9mm.
Pros & Cons
- Pro: Extremely low felt recoil for a full-size 9mm — the rotating barrel really works.
- Pro: Ambidextrous controls make it friendly for both left- and right-handed shooters.
- Pro: Interchangeable backstraps let you dial in the fit without tools.
- Con: The trigger has a bit more take-up than some modern striker-fired pistols — it’s a duty trigger, not a match trigger. If you’re used to a crisp break, you may want to budget for an aftermarket trigger job.

The PX4 Storm costs about one-third of those custom builds, but still delivers Beretta’s legendary reliability. If you’re looking at the beretta px4 storm full size .45 acp pistol, the same rotating-barrel design works in .45 ACP with a 14-round magazine.
FAQ
Is the Beretta PX4 Storm a good gun?
Yes — it’s one of the most underrated full-size pistols on the market. The rotating barrel system gives you noticeably less recoil than a Glock 17 or SIG P320, and the reliability is proven by military and law enforcement adoption in several countries. According to Beretta’s own testing, the PX4 has a mean rounds-between-failure rate exceeding 5,000 rounds. It’s a good gun for home defense, range use, and even concealed carry with the right holster.
Does the Beretta PX4 Storm have a safety?
Yes — the PX4 Storm comes with an ambidextrous frame-mounted safety/decocker. You can carry it cocked-and-locked (safety on) or decocked with a double-action first pull. The safety is positive and easy to reach with your thumb. If you prefer no safety, the PX4 is also available in a “G” model that eliminates the safety lever and uses a decock-only configuration.
What are the beretta px4 storm full size specs?
Barrel length: 4.0 inches. Overall length: 7.6 inches. Height: 5.5 inches. Width: 1.42 inches. Weight: 27.7 oz unloaded. Magazine capacity: 17 rounds (9mm), 14 rounds (.40 S&W), 12 rounds (.45 ACP). Sight radius: 6.0 inches. Trigger pull: approximately 6.5 lbs double-action, 4.5 lbs single-action.
Is the PX4 Storm better than the compact version?
It depends on your use. The full-size gives you a longer barrel (4.0 vs 3.2 inches), a longer sight radius, and higher magazine capacity. The compact is easier to conceal and weighs about 4 ounces less. For home defense or open carry, go full-size. For daily concealed carry, the compact may be a better fit. Many shooters own both.
