Can some one help. My son and I were shooting my glock 23 Gen 4 using Tulammo when he was double tapping a live round got jammed in the chamber and the slide will not move. The trigger is not set I took the slide off and and the back plate and I took out the striker. put the slide back on and tried to work the slide but it is still locked it only moves enough to get the slide off. Im wondering if the casing didn't swell.Can any one help.
