The Beretta Px4 Storm Full Size is a 9mm Luger DA/SA semi-automatic pistol with a 4-inch barrel, 10+1 capacity, and a polymer frame with Black Bruniton finish. The rotating barrel system reduces felt recoil at the cost of a heavier pistol compared to tilt-barrel designs. This configuration is California-compliant.

Features 

The rotating barrel reduces perceived recoil compared to a tilting-barrel pistol of similar weight. Interchangeable backstraps let shooters fit the grip to their hand. The ambidextrous safety and decocker make the gun accessible for left-handed users. Three-dot fixed sights work for fast target acquisition at typical handgun distances. The 4-inch barrel balances maneuverability against sight radius.

The Px4 Storm draws positive feedback for its comfortable grip and how the rotating barrel reduces recoil during rapid fire. Reliability and accuracy at the range are frequently praised, and users in defensive contexts report confidence in its performance.

The DA trigger pull is heavier than some prefer, which affects accuracy for shooters who haven't practiced the long first pull. The 27.7 oz weight is occasionally cited as making it less convenient for concealed carry compared to lighter alternatives. For California buyers, the 10-round capacity limit is a common point of frustration since higher-capacity versions exist in other markets.
