I've been gone for a while, but just picked up the guns to start shooting again. I went to the range and... problem. About 50 rounds in, my Beretta 21a Bobcat's slide stuck in what seems to be the rear position. I'm not sure if it's truly ALL the way back but it's close. By stuck, I mean stuck. I can't get it to move at all. Anyone have a clue on this one? (forgive the greasy gun, I've tried to lube it up to get the slide to release.)
