Our last outing was not too fun - too many FTE's / jams using Herter's ammo. Went out today and blew through some PPU ammo - what a difference. Smooooooth. No problems at all. Gonna have to get some more. One thing we have to work on; however, is counting to SIX! I know its not good to dryfire, but too frequently we hit the end of our magazine, and, because we're not counting and there's no slide lock, we pull the trigger one too many times. So, question: are we messing up the gun by pulling the trigger a SEVENTH time - that is, of course, one time too many 'cuz we're not counting. Yes, I know, its lame; nevertheless, there you have it. Am I gonna break my gun accidentally doing this?
