So I picked up my XDm 9 4.5 on Saturday and went to the range with my brother and my wife on Sunday. Between the two of us, the wife and I shot 500 rounds through the weapon with no problems at all. I'll still extremely new to shooting, so I was working a lot on my grip, my stance, all that stuff. Even so, my groupings started to get tighter through the day. My brother and I got another trip to the range scheduled for Wednesday night, and I can't wait.
