The KGM SMG9 stands as an exceptional submachine gun or PDW (Personal Defense Weapon) suppressor, crafted for hard-use scenarios and capable of handling even full-auto fire with supersonic .300 Blackout ammunition.

Engineered with precision, the SMG9 efficiently manages gas flow to minimize disruption to the host weapon’s performance. By redirecting gas away from the bullet’s flight path, it enhances precision, while the engineered gas flow passes through the suppressor to reduce flash, recoil, and sound—ensuring superior accuracy, repeatability, and sound suppression.

Built to endure, the SMG9 boasts high-quality materials and construction, guaranteeing an extended service life even under the rigors of years of hard use. Elevate your submachine gun or PDW experience with the reliable and high-performance KGM SMG9 suppressor.
