The Griffin Armament Micro Carry Compensator is engineered for concealed carry - it adds only a few tenths of an inch beyond a standard thread protector but delivers real recoil mitigation and gas redirection from its 17-4 stainless steel ported baffle. Fitment Thread pitch: 1/2x28 TPI (9mm) Compatible with any 9mm pistol barrel threaded 1/2x28 - Glock 17/19/26 threaded barrels, Smith & Wesson, Sig, and other Glock-pattern host builds Holster fit: designed to clear most Glock 19-length carry holsters - verify with your specific rig Specs Material: 17-4 PH stainless steel with black nitride finish Design: single-baffle patent-pending port for muzzle control Length: adds ~0.6" beyond thread protector footprint Weight: minimal - CCW-friendly Thread: 1/2x28 TPI, 9mm bore Install and function test Hand-thread the Micro Carry Comp onto a clean, lightly oiled barrel and torque per the barrel manufacturer's spec. Function-test with your carry ammunition before any duty or self-defense use - adding mass at the muzzle can subtly change the timing of a 9mm slide, especially on lighter carry loads.
