TPRCSN Micro Comp, Compensator, 9MM, Copper, 1/2-28, PVD TP-SMICRO-C True Precision was started by some highly skilled individuals who had not only a passion for developing the highest quality aftermarket parts but who also had access to high quality US made materials. They have taken that wealth of knowledge and utilized it to create the True Precision Micro Compensator for pistols. These compensators are designed specifically for use with True Precision barrels" but they are also compatible with most 9mm and .380 ACP pistols with a thread pitch of 1/2x28. Three slotted ports and a tapered front crown help to strategically redirect gasses away from the muzzle to reduce the amount of felt recoil for the shooter. The True Precision Micro Compensator is available in two unique designs" S-Type or Y-Type" and each comp is designed and made in the United States of America!
