Has anyone used a KKM Precision barrel in a Glock 21? I've been told they are very accurate barrels. Just curious if they are any/that much better then the factory barrels and worth the money.
I`ve used a KKM threaded barrel in a Beretta.Honestly I couldn`t tell ya it made that much of a difference.The threading an craftsmanship was great.But all in all the groups didn`t improve enough to justify $250.00+.Sorry no experience with a Glock.
I have them in my Glock 17, 22, 21, and 35. I have found them to be more accurate than factory barrels and have had zero issues with reliability. I have run all have them for what I consider fairly hard too.
