The PX4 Storm Subcompact in .40 S&W is the smallest .40 S&W rotating-barrel pistol Beretta produces. Harder to shoot than the 9mm subcompact due to .40 S&W recoil in the lighter, shorter platform, but the rotating barrel still provides meaningful reduction versus competing subcompact .40 S&W designs. Type: Semi-Auto Pistol Action: Double-Action/Single-Action Caliber: .40 S&W Capacity: 11 Year introduced: 2007, Italy Weight: 25.9 oz Overall length: 6.2" Status: Active Intended use: defense, concealed carry
