I've shot some of the 180gr TMJ 10mm in my Glock 20. Stock setup on the gun. I was actually getting random slide locks with other ammo, none with the Underwood. Can't imagine how this would be ammo related, but just noted it didn't happen with the Underwood. Ran 100%, and pretty clean. It's definitely stout at 1300fps rated, but it's NOT hard to handle at all IMO in the G20. I didn't see any overpressure signs, no smilies in brass or pushed primers. Very high value at $27/box.
