I have a handgun course coming up and I guess I won't be taking my p226 9mm. Slide just won't lock back MOST of the time! I've tried everything! •Shot it with my thumb away from slide lock lever by adjusting my grip. •I've shot it with one hand •I've cleaned and inspected all my magazines...

I've got 1500 rounds through my p226. I'll shoot 100 rounds through it and it'll be fine then out of nowhere the slide won't lock back after I empty the magazine. Sometimes it does sometimes it doesn't, it's making me bananas. I checked the springs in the magazines and I know I'm not limp...
