Ok, I am not new to glocks but I am new to owning a gen4. I was returning from the range and as usual, cleaned my gun. When putting the recoil spring back in, mounting the slide on the frame and racking the slide... the recoil spring came out the front. I was like What the??? I took it back apart (removed the spring) and looked at the area where the recoil spring seats.. I tried to wiggle the spring through myself and it will not but how in the heck did it come out on its own? I am baffled and honestly and a little concerned that this may occur in a real crisis. I have stopped carrying it for now until I get a idea on what is going on.
