Can the CGW parts be polished to the same effect that you get from shooting it? All morning we've been discussing the merits of shooting in DA. The effect on the gun is without question. I've been dry firing the Tactical along side the Phantom, and they are worlds apart, with the same CGW parts.
We need a CGW "Perfection Package"!
My experience with other platforms is that polishing can get you a long long way down the road but there is no substitute for having the parts installed and functioned repeatedly to really match of the surfaces. Light pulls can be accomplished on the bench but smooth...smooth takes trigger pulls and rounds down range. I had/still have some wheel guns that have tuned triggers. The ones that have been tuned are excellent. The ones that have been tuned and shot a lot are incredible.
The gold to which CM referred to is the Wizard's gift from knowing what needs how much. Not sure that is a skill that can be obtained without a lot of experience and an inherent natural ability to be the best.
