Ugly but they'll go bang every time you pull the trigger. Kinda like that sure thing midnight drunken booty call.
Be sure you get lots of practice to get accustomed to that terrible trigger. I'm repeating myself, but it's just like walking barefoot and accidentally stepping on a mouse: increasingly resistant squish followed by crunch and finally pop. Maybe that's not a fair comparison- stepping on a mouse isn't anywhere near as repugnant.
@chris_1001 - Did you buy yours at the Mill via banging on the door of a closed shop while asking, "Do you sell Glocks?"
Honestly? I fire it just fine with the stock trigger.
I'm not picky about triggers. I learned to shoot in the Army, where you get what you get and you don't get upset. I'm adaptable. I've never had a hard time adjusting to different triggers.
