I have a "built" P10C with roughly the same amount invested in it as I would have in a tuned Shadow. After thousands of rounds of dry fire and competition, I simply don't shoot it as accurately(at match speed or slow fire) as I do my hammer fired CZ's. I'm certain it's me not the gun.
If you're a striker(glock) person, the P10 series is great. If your a hammer person like me, stick with a Shadow or Shadow2 and avoid the expense of finding out the hard way.
Cajun Gunworks is offering a "competition" striker kit that should help with pull weight and creep. I have one on order for my P10 to give it one more try. FWIW, I shoot mostly Steel Challenge, so I'm transitioning during recoil, not pushing for a quick follow up shot on the same target. If I was shooting USPSA or IDPA, I'd want a metal framed gun for the extra weight. That's just me though, everyone has their own preferences.
