OK just got back from the range today and experienced a problem. I have about 300 rounds through my M&P .40. Loaded my weapon and after two rounds gun locked up.Slide did eject on second round. Could not rack slide but was able to push slide forward as slide did not close fully. I can only retract slide a quarter inch or so. Any ideas on how to fix this? I pushed slide against range table but got no movement. Any way to get slide off gun? I drove the pin out next to the take down lever but can't get lever out more than an 1/8 inch. Anybody have any suggestions? Thanks Ron Wanna kill these ads? We can help!
