New to this one and used it a few times. Had a squid load yesterday and what am wondering why I could NOT get another round in the chamber.. I realized I had an issue, but no matter what I tried, the slide would not completely close, yet the squid load was not even close to the next round. Ideas why? I don't want to mistakenly be unaware of a bullet being stuck, and yet the slide closes all the way making be believe things are fine.
