Hello I just got a new glock today its a glock 17 I took it apart forgetting to remove the magazine and putting it back together with the magazine I was wondering if there could be anything wrong with it if I put it back together with the magazine in I noticed it was alot harder to do but was wondering if its bad or what could happen. Also on the back of the gun when fieldstriped on the frame there is a little metal piece I noticed that was bent normal??? and one more question When the gun is not cocked i notice a little rattling noise was wondering if that is normal also thanks guys
