Typical Glock. First one?

As for the trigger, it's easy (with a little practice) to get into the habit of bringing it right back to the wall after each shot, and then the break is rather like that on a single action auto. People mess up when they try to squeeze it like a double action revolver, sweeping it all the way through. You need to feel the wall and the break every time to get good accuracy, and with a little practice this can become a fast and automatic process. Before you know it, you will be accurately firing double and triple taps that way like a two or three shot burst subgun. Well, at least in a 9mm. I don't much shoot my 21, so haven't gotten to that point with a hard kicker like that, but who knows. Glocks are great guns, and will serve you well with a little well considered trigger time behind them.
