I posted in general and they refered me here. I have a 29sf and a Lone wolf .40 conversion barrel.Today it shot for a while then jammed. The slide stayed back and the round seemed to be pinned under the feed ramp. When I dropped the mag the round stayed in the mag but the slide was locked back and would not release. I finally just bumped the slide pretty hard and it released. Tried it 2 more times and the same thing after 2-3 rounds. I was using Blazer ammo which cycled fine for 50 rounds last weekend. The only upgrades to the pistol are night sights and a 3.5 ghost trigger. Any ideas?
