Just finished installing the CGW 75700 kit on my P-01. Including polishing the rails and the trigger bar, it took 4 hrs. Actually easier than the kit I put in my SP-01. I left the heavier trigger return spring in because I didn’t want the pull too light. Turns out I didn’t have to worry about it as the pull come in at 5 lbs even. That sounds high but the break is so clean it doesn’t feel like a 5 lb pull. It breaks without any perceived creep. DA maxed out my 8 lb scale but I’d say it’s 10 lbs judging by how much the indicator moves beyond 8. I also installed a stainless guide rod which will except either flat or round recoil springs. Once again I’m impressed with CGWs quality, customer service and quick delivery. Couldn’t be happier.
