Noveske Thread Protector Features The Noveske Thread Protector is machined to fit 1/2x28 threaded barrels the most common thread pitch found on 9mm pistol barrels. Threading on an exposed barrel can be damaged by impact dirt or debris when a suppressor is not attached and this protector shields those threads from everyday wear. An included o-ring helps the protector stay seated firmly on the barrel preventing it from loosening during normal handling or holstering. This simple design keeps the muzzle threads ready for use whenever a suppressor needs to be attached. A knurled exterior finish gives the shooter a secure grip for hand-tightening or removing the protector without needing tools. Finished in matte black the protector blends in with most pistol finishes rather than standing out. Noveske builds this thread protector as an affordable practical accessory for pistol owners who alternate between suppressed and unsuppressed configurations. For any 9mm shooter who wants to keep their barrel threads protected between suppressor sessions the Noveske Thread Protector is a low-cost easy solution.
