Beretta PX4 Storm A polymer pistol designed and sold by Beretta, it is chambered in 9mm, .40 S and .45 ACP. The polymer frame has reinforcements for added strength, probably a subtle nod to Glock’s blowing up due to owners shooting hand loaded ammo. Not really a fan of the lines of this gun, I would take the older Beretta 92FS over this in a heartbeat.
The GLOCK 17 Gen4, in 9x19, introduces revolutionary design changes to the world's most popular pistol. The Modular Back Strap design lets you instantly customize its grip to adapt to an individual shooter's hand size. The surface of the frame employs the new scientifically designed, real-world-tested, Gen4 rough textured technology. Internally, the new GLOCK dual recoil spring assembly substantially increases the life of the system.
