I’ve been having problems with my CZ-85B‘s slide locking back part way through a magazine. I’ve worked to eliminate the obvious stuff like limp wristing it, but unfortunately, no matter who’s firing it, it does that. So I called CZ‘s customer service, got over to one of their gunsmiths, and described what was going on. He agreed with my diagnosis of the slide release spring going bad and put one in the mail for me. Without asking for serial number or method of payment. Once it gets here, I’m going to have some fun installing it, but hopefully that’ll fix the problem.
