Striker fired pistols are becoming an important segment worldwide for the Military & Law Enforcement sector. The Beretta APX, utilizing a removable, serialized chassis frame, can be easily modified with a replaceable grip frame housing and is simple to disassemble and maintain. The lightweight frame housing is made of fiberglass reinforced technopolymer. The APX’s extremely low profile and snag free design make it easy to carry and draw from a holster. Ease of use was the key driver in the development of the APX. A slide catch lever is located on both sides of the frame. The operating/locking system is based on a tilt-barrel, locked breech. Beretta APX pistols have a unique feature that allows the user to deactivate the internal striker mechanism prior to disassembly. This means the pistol can be field stripped without pulling the trigger. The Trigger Safety stops the trigger from traveling rearward through inertia, in the event the pistol is dropped. When the trigger is intentionally pulled, the Trigger Safety is instantly deactivated.
