The Gemtech GM-45 Silencer .45 ACP .578-28 Includes Lid USED is a purpose-built pistol suppressor that leverages Gemtech’s patented G-Core baffle design for reliable sound reduction and easy maintenance. Constructed from lightweight aluminum with a matte black Cerakote finish, it offers a slim 1.375" diameter profile and 7.6" overall length, keeping your handgun setup balanced while reducing muzzle report.

This GM-45 model is optimized for .45 ACP but is also compatible with select 9mm, .40 S&W (dry only), and 10mm (dry only) hosts when used with the appropriate piston. Delivering approximately 23 dB of reduction dry and up to 35 dB wet, it is well suited for range use, training, and recreational shooting where comfort and communication matter. The user-serviceable G-Core allows full cleaning of the unit, and the included .578-28 piston provides straightforward mounting to common threaded .45 ACP barrels, reflecting Gemtech’s focus on practical innovation and shooter-friendly design.
