Welcome to the forum and hope you enjoy your P-10C.
I got one of the first ones to hit the US as a production model and immediately had to make some modifications. I smoothed down the grip areas first and worked the slide release and the mag release a bunch and, with my pistol, that took care of the initial concerns. But the trigger safety was still an irritation so I fixed that. Then I concluded the pistol had real promise, for a striker fired gun, so I experimented with additional grip and trigger modifications to get the pistol to fit my long fingered hands a little better, using Sugru and JB-Weld.
When CGW finished development of some aftermarket parts, I sent the gun in for a slide cut for a red dot and an assortment of parts. I am going to shoot the P-10C in a bullseye match when I get it back, just like I've done with the P-07 and P-09, alongside my usual steel 75B and 97B"E" bullseye match pistols. (The steel guns with CGW bushings are excellent bullseye match pistols, by the way.)
I'm made extensive changes to every single one of my CZ pistols, not so much to correct problems with the original design, as to make them comfortable and consistent to shoot in a bullseye match condition. I do carry the P-07 with open sights instead of a red dot, Sugru and all. My guns are ugly, can't be sold even if I wanted to, and, according to some YouTube comments, I should be put in jail for defacing my own property.
But, I get good results, have won several bullseye matches with my plastic guns, and have a very enjoyable hobby and have lots of internet friends as a result.
I think CZ made a mistake in sending out too many pre-production "test and evaluate" guns that didn't have the rough slide and mag releases and had some smoother trigger parts than the production versions and they got everyone very excited. The production service guns were a little more conservative and stiff and the difference has irritated a lot of folks. I am not one of them, because I fully expected to change a lot on the gun anyway. I am still very confident the P-10C will be just fine for my intended purposes, which include irritating the crap out of my bullseye buddies that someone with a 4" plastic striker-fired service gun can win a centerfire bullseye match, and shooting a 6" group at 100 yards from a rest. That's the plan and I'm sticking to it.
