The Beretta’s APX is designed specifically for military and law enforcement operators. It delivers superior performance in durability and reliability, ergonomics, trigger, and modularity. It utilizes a removable, serialized chassis frame, striker fire operating system, three interchangeable back straps, full length slide serrations, reversible magazine release, and an ambidextrous slide stop. The APX Combat incorporates the ability to easily mount a red dot optic and has a factory installed 1/2x28TPI threaded barrel. The pistol features a factory slide cut to accept one of four different optic plates. The pistol plates support Mini-Red Dot Optics from Burris, Trijicon, Leupold, and C-More. Included is a fixed blanking plate that covers the slide cut and allows the pistol to be used sans optic mount. This model has a 4.9 barrel, black finish and comes with a 10-round magazine.
