My Glock 21 has developed a problem that I noticed last time I shot it. The slide lock now engages randomly through magazines and once engaged must be manually disengaged by manipulating the lever with my thumb. Racking the slide doesn't release it either . There's no upward pressure being applied and it acts the same with the gun empty. I don't want to start ordering parts until I check that there isn't an easy fix.
