Beretta PX4 Storm F 9mm | 4″ 17+1 | JXF9F21

The Beretta PX4 Storm Full (model JXF9F21) is a full-size, polymer-frame semi-automatic pistol configured for 9mm with a 4.00″ barrel and a 17-round magazine capacity. It uses Beretta’s rotating-barrel locked-breech design to manage felt recoil and maintain a controlled sight picture. The pistol includes ambidextrous controls and an accessory Picatinny rail for lights or lasers. For a compact red-dot that pairs well with this platform and stays well under $1,000, consider a Trijicon RMR or equivalent footprint optic.
