What’s Included

The FX-9 P4 operates on a simple, reliable blowback system and is configured for Glock-pattern double-stack 9mm magazines. With the included 50-round drum, it offers a 50+1 capacity in a compact format built around a 4 inch barrel.
Billet-machined aluminum receivers with a hard-anodized finish provide a solid foundation. Controls mirror the AR-15 layout, including an AR-15–style rear charging handle and a manual safety selector marked "S," making operation familiar and straightforward.
The free-float aluminum M-LOK handguard gives ample mounting space while keeping weight out front under control. The receiver has a T-marked Picatinny rail; the handguard’s top is mostly M-LOK with short Picatinny sections at the rear and front, and this pistol arrives with a Bushnell red dot already mounted.
Ergonomics include an A2 polymer pistol grip and a polymer stabilizing brace. A short cylindrical muzzle device/shroud is installed at the muzzle, and ejection is to the right side.
