I am guessing that is a gen 4, my buddy just got one. I have have gen 1, got it about 25 years ago. I don't carry it any more, the 9 just is not big enough. However, it is fun to shoot, good luck with it. I know you can change the mag release if you are a lefty.
Well I will put it plain and simple. I am 5' 10" and finally got up to 135 lbs. My problem isn't with calibers but with size for conceal. The other problem I have is having small hands it makes too many of the larger caliber guns hard to get a good grip on. I love my 1911 45.'s but I want something easier to carry and hide and on a plus side my wife likes it too so she can carry it when I am using one of the others. I actually already changed the mag release, as the dealer had changed it to work for the lefty customer who was about to buy it. So I'll give it a few tries at the range and if I don't like it the wife can have it.
nice GLOCK :>) and great price
My wife likes to shoot mine as well, I carry my 1811 frame sig 45 now. It has become my favorite. I used to carry a springfield xd 40 cal. Have fun at the range with your new gun, it is an easy gun to shoot.
