Ok, I just got it apart and put it back together. While pushing forward with a small amount of force, I pulled back on the trigger and it sounded like a normal dry fire. In conjunction with the clank, the slide move forward beyond the point of resistance. I have reassembled and test fired. Everything seems to be working fine now.
However the thing that concerned me in the first place, before I started messing around, is this. The pistol fell a few feet onto a carpeted floor. Did not worry me. After all, it is a gun,a Glock,and not my AR. However when I picked it up and shook it around a bit I noticed that what used to be a noticably tight fitting slide now wiggles side to side a bit. I remeber in the past being impressed at how tight the slide fit to the frame and that there was no rattle. What's the deal now, and is this normal for a Glock slide to frame fit?
Lastly, should I be worried that something may have been damaged in the first episode? It seems like the trigger pull is lighter now.
Thanks for the help.
