My post CZ CBOB was a dog. I could not get through a magazine without slide locking back, and failure to feed, (not at the same time) and getting hit in the face with cases. In fact, due to lack of imagination, I kept shooting without realizing that they were denting my plastic lenses. Oh well, I guess it was time for new lenses.
My friend BluesBear worked on it a bunch and it is much better, only the occasional FTFeed and occasional thump in the face. But I still have to wear safety glasses over my real ones.
On the good side, it is very accurate and has a great crisp trigger. We are thinking of maybe the other problems might require some polishing of the chamber. Might be asking 1911Tuner for some more tips.
