Took my new gen4 G19 to the range today, very pleased I'd have to say. Ran about 250 rounds down range and ate everything with no problems. Took a few shots to get used to the trigger as im used to shooting SA and DA/SA handguns. By the end of the day, 3" off hand with my Kimber and slightly larger groups with the glock at 25 yards. I was a little nervous after hearing all the trouble with the gen 4's, no such issues. I will now carry with confidence in my new little glock!
