I've owned my Glock 22 for about a year, but only have about 400 rounds through it. I was always taught to NOT use the slide stop to release the slide, instead I use the overhand method to put the slide back and let go. No problem. However, recently (as in right now, I just recreated the 'fluke'), here is what happens. 1. Gun is empty, no magazine, not chambered, slide completely back (open). 2. Place a loaded magazine into the gun, and do it with a good amount of force. 3. The slide will automatically go FORWARD Is this normal, or is this somehow a sign of a worn out slide stop that can't keep the slide back? As I said I never use the slide stop which is odd.
