Short-Stroke Piston, Adjustable Gas

At the heart of the G3 is a short-stroke piston operating system with a 3-position adjustable gas system, so you can tune the pistol for different ammunition and operating environments. Steel-reinforced components in high-wear areas add durability.

Ambidextrous and Easy to Run

Controls are fully ambidextrous, and both rear and side non-reciprocating charging handles give you flexible, intuitive manipulation. A Matchlite Duo curved trigger and SIG flash hider/compensator complete the package.

Compact 11.5-Inch Configuration

The 11.5-inch pistol configuration delivers piston-driven reliability in a maneuverable package, with the free-floating M-LOK handguard giving plenty of room for lights and accessories.
