The Beretta Px4 Storm Compact offers a full grip, a MIL-STD Picatinny rail, an ambidextrous slide stop, and an integral/retractable lanyard loop. The Px4's rotary barrel system reduces recoil for faster follow-up shots, and the Compact model also accepts full-size magazines. Technology, precision, and a smaller profile make the Px4 Storm Compact the ultimate in concealable and duty-ready pistols. This 40 S&W model comes with a 12-round magazine.
