About 2 hours ago I picked up my first Glock and it's a gen 4 G23. I went to a local range and loaded one magazine and it wouldn't go into the gun. I smacked it a few times and it eventually locked into place but it took a lot of effort. Then I couldn't chamber a round. Then slide was stuck forward. I took out one round and tried again and it was very rough and took a lot of strength to rack the slide. Is this common on all glocks or is it just because it's brand new? I've owned an xD45, Sigma SW9VE and now an xDm 9 and they've never given me any issues like this. Any one else have this problem?
