thinman1911--I shot IDPA SSP and later ESP for a few years but used Sig DA/SA pistols before I got a CZ.
I can only add that a perfectly acceptable trigger for IDPA can be had WITH the firing pin safety block models. I've shot bullseye also, where there is a lot of time between shots, and I can barely feel the difference between a CZ with and without a firing pin safety block. I don't think you will notice it at IDPA shooting speeds.
Not only that, but I actually prefer having the FPSB in a run and gun match pistol, just for safety reasons, especially when I was learning. Folks trip and fall, drop the gun, lots of instances where the firing pin safety block was a welcome safeguard. Not nearly as likely to be needed in a slow, stationary match like bullseye.
And a reminder, that you are already aware of based on your question, you cannot remove or defeat a safety device from a gun that had one originally.
If I were to go shoot IDPA SSP next weekend, I would pick a P-10C now over my old P226 Sig, I think. Handles perfectly, trigger feels the same from shot to shot, fits me well, reliable, accurate. And I would have very few down points, but would be so slow that I would finish in the lower third of a 100 shooters in a local match. And it would take me 10k rounds to just barely get back in to the top 1/3, which is about as good as I could ever do. Too many young guns out there who shoot well, can move well, and practice lots. But I wold have had a good time!
