About This Firearm
The Beretta PX4 Storm is a polymer-framed DA/SA .40 S&W built for duty and home defense. Its barrel rotates to unlock instead of tilting, which lets Beretta sit the bore low in the frame and keeps muzzle rise down on a .40 case. The magazine is a staggered 14-rounder.
The safety lever also decocks the hammer and sits on both sides of the slide. The three-dot sights lift out of their cuts for replacement with other heights, there is a MIL-STD Picatinny rail under the barrel, and the backstrap, magazine release button and slide catch can each be swapped for a different size. Nothing on the slide takes an optic. At 7.55 inches long and 5.51 inches tall on a 4.02-inch barrel, this is a full-size duty gun.
If you're cross-shopping, the Smith & Wesson M&P 40 M2.0 holds 15 rounds on a 4.25-inch barrel and is striker-fired, so there is no first-shot double action to train around, but S&W has stopped making it. The FN FNX-40 is the closest DA/SA match, with its own ambidextrous decocking lever, three magazines in the box and a 4.0-inch barrel, and FN has dropped it as well, so both rivals are used buys.

Strengths & Limitations
- The locking lugs sit around the muzzle and Beretta enlarges the outer barrel diameter there for a constant barrel-to-slide fit.
- Three backstrap thicknesses are offered, and the magazine release button comes in small, large and extended versions.
- The slide carries front and rear serrations, cut so it can still be worked with wet hands.
- Nothing on the slide takes a red dot.
- A slide-mounted decocker is a Beretta habit to learn, and it is further from the thumb than a frame-mounted lever.

Frequently Asked Questions
Does it have a magazine disconnect?
No. Beretta states the pistol will fire a chambered round even if the magazine has not been inserted or has been dislodged.
What is the rifling twist?
1:15.75 right hand for the .40 S&W version, which is a slower rate than the 9mm models use.
Is there a version without the manual safety?
Yes. Beretta’s model G has the decocking lever and no manual safety, and the model D is double action only.
