NO weird thread pitches, NO proprietary barrels. Use what you’ve got!
The TBRC M&P Micro Comp is threaded in the standard 1/2×28 thread pitch. It will work on most 9mm M&P barrels threaded in that pitch, including most 40-9 conversion barrels! The Micro Comp only adds about .50″ to the end of your threaded barrel. Comp mitigates recoil and keeps your gun flat throughout recoil. Shoot faster and flatter with the TBRC Micro Comp!
