G34's I've been running them for 4 years now, about 75 matches . avg 173 PF , they hold up just fine . you can do all the work on them your self, inexpensive and shooting open is a blast.. John from SJC is a great guy to deal with. I know a couple of guy's that made master with open Glocks . Being old and retired I get great satisfaction that my gun's run great and I'm having fun
