Refurbished duty weapon, 40 S&W one magazine. Beretta px4 storm double / single action hammer fired. Designed to meet the most stringent military standards of durability, the PX4 has been reported to fire well over 150,000 rounds with zero part breakages. This pistol features a cold-hammer forged, rotary barrel encased in an ultra-tough slide machined out of solid bar stock. Besides being one of the strongest actions available, the rotary barrel dissipates recoil away from the shooter’s hand and greatly reduces muzzle flip.
