I just bought a CZ 75-P01. The double-action is long and gritty. I was looking at a CGW kit that has hard polished parts and springs. There is also M-carbo and it's just a spring kit. There is a BIG price difference between the two. I know CGW should be the better one but has anyone tried both? Just interested in what y'all found? I like tinkering with my guns and I like hard parts and will most likely buy the CGW.
