Gmax9

1.135 OAL as well. I tried 1.140 and got the periodic hang up where rounds wouldn't feed up the magazine tube. That worked fine for my Glock 35 and 24.

I have a Glock 24 that I run a KKM 40 to 9mm conversion barrel in with no issues. I'd guess 1,500-2,000 rounds down the tube with no problems.
