Went to the range Saturday to Shoot some 9mm, some 38's and brought a Glock 22 to keep my competency level up as the gun serves a defensive role at home. I shot my 22 second and racked a round in. When I shot my first round hit about 6 inches right and didn't eject the round. I'm not a great shot by anyones standard but like many people my first shot is often my best. I was surprised because I'm not sure I can ever remember that gun not cycling cleanly and I have owned it since 1992 and have shot it allot. I'm sure some of you can guess where this is going. I reached down and picked up the spent casing and to my surprise it was a 9mm and split to the base. I'm surprised it chambered and fired even more surprised it was on the paper. Somehow I loaded a nine in last on top of the 40. A wake up call for me to pay closer attention. Not proud of my idiocy, just a reminder at my expense that things can go wrong fast.
