I had a 2017 P-01 and I still have a 2013 built C-100. The P-01 was fine, but IMO, the C100 conceals better, has a better trigger, and the overall build/fitment is just better. Right now, I'm cleaning the C100 from last weeks range visit, and I amazed how tight the slide fits to the frame (no oil or grease), the barrel locks up like a custom fitting, and the barrel bushing has ~.003 clearance to the barrel OD. I probably have 2000rds through the C100 with no failures that I remember, and accuracy is easily on par with my full size CZ's.
