G21 Gen4 Lone Wolf Threaded Barrel 5

Posted by Darkstar on 7th Dec 2022

I received the barrel on time without service interruption or damage. The barrel itself has a durable coating and should hold up well under continuous firing. Barrel exit and crown have been accurately machined. The barrel was an exact drop in - no nonsense fit. I was happy to find a threaded barrel for my G21 -- as most people, caught in the grip of guns discharge, usually shy away from guns chambered in anything larger than a 9x19. Fortunately, that is not the case with me! Thank You!
