Product Overview  This is the micro compensator from True Precision that has a similar form function as a thread protector but offers a slight reduction of recoil and a better look to your handgun!  Designed specifically for True Precision barrels, but ready for most 9mm and .380 barrels with 1/2x28 Threads.  Tension lock o-ring for hand-tight installation to prevent back off.* Made from USA-sourced solid 316L Stainless Steel bar stock. Designed, assembled, and machined in the USA. The multi-port design includes three slotted 90-degree ports with a tapered front crown to direct gasses away from the muzzle and reduce felt recoil.  The overall length is .787". Outside diameter at widest: .745", with a taper to .650" at narrowest (barrel end).  *Optional use medium hold thread-locking compound for semi-permanent installation.
