PART, THREAD PROTECTOR, 320,226,229, 13.5X1MM LH

This thread protector is manufactured to protect the barrel threads on SIG P320, P226, and P229 pistols when a muzzle device (compensator, suppressor adapter, etc.) is not installed. Machined to the 13.5 × 1.0 mm left-hand (LH) thread specification, the protector screws onto the muzzle to shield the threads from damage, dirt, and corrosion during storage and use. Constructed from durable steel or aluminum depending on SKU and finished to match firearm aesthetics (nitride/black anodize recommended), it features knurling or flats for easy hand or tool installation and removal. Simple, lightweight, and essential for preserving thread integrity on threaded barrels.
