Beretta's Px4 Storm features an exclusive Beretta-designed locked breech with a rotating barrel system which reduces felt recoil and muzzle rise. The chrome-lined barrel provides extreme corrosion resistance and also features a deeply-recessed combat muzzle crown to protect the rifling. The light durable frame employs modern thermoplastic technology through the use of technopolymer-reinforced fiberglass and features an integral Picatinny MIL-STD rail. The Px4 Storm has an ambidextrous safety/decocking lever and a reversible magazine release and it may be configured with backstraps. Includes magazine and backstraps.
