DDustin Posted September 12, 2015 Share Posted September 12, 2015 (edited) I just got a 5" 9mm KKM barrel for my new competition build and I'm about to order some more ammo. For those that run a KKM barrel, what bullet weight does it seem to like best? Edited September 12, 2015 by DDustin Link to comment Share on other sites More sharing options...
