On my model 63, I had problems with extraction, fixed that. On my Model 18 the brass actually recoils back against the recoil shield but doesn't retract ( or bounce, which ever term sounds better ) back all the way into the chamber, which binds up the rotation. Every thing is up to standard on my revolver and CCIs are the only shells which this binding occurs. I don't worry about it, I just use the CCIs in my other guns, and different brands in my Model 18. In fact I have conversion units for both one of my 1911s and my Hi Power and I have found that CCIs work best in them. So I just compromise and go on shooting
. It is not a big enough matter to worry me.
