First of all Ill give you guys alitle history of my CBOB. I've shot around 300-350 rounds through it. About 60 rounds or so ago I sent it to Dan Wesson to have some problems fixed. What was happening was the hammer was dropping but the round wasn't firing. So Dan Wesson fixed it by, Throating the barrel, re-polishing the fed ramp, and doing a trigger job. So all is good, until I took it to the range today. Now what is happening is, the round isn't feeding all the way into the barrel. Its going far enough into the barrel where I can barley see the rim of the shell. This is fixed by re racking the slide. This happened 2-3 times while shooting 60-70 rounds. Also the slide didn't lock to the rear 2 times. What is going on? I love this gun, but its really starting to worry me. Thanks for your time and please help me out.
