Tecolote:
I said the "DESIGN" may be better.
I think, however, that a properly fitted CZ-75 will match an equally well-prepared Sig 226 in most ways. And both shoot about as well, out of the box -- much better than other guns. (The best CZ-75s are those which are made by CZ...)
I don't know of many 226s that will do that well at 100 yards. You may have a good one, but don't expect all 226s to perform the same. At that range, its probably more the singer than the song (i.e., more shooter than the gun.)
Similarly, I don't know of many CZ-75s that do well at that distance, either, but there are probably exceptions.
Remember: we're talking about handguns. At that range (100 yards) you should be using a rifle or carbine, or running like hell... ("Serpentine, Shelly, Surpentine.)
A Sig P-210, however, will outshoot any 9mm pistol at that distance -- including the P-226. I have one, and love it.
(If I could afford one, and if they were being imported, I'd get a P-210-8, with the American-style mag releases and a heavier frame. But $2,300 is just a bit over my spending limit.)
I have nothing against SIGs. Fine guns. I've had three, and kept the best. They are among the best, no-tweaking required guns available.
But then, so are the CZs (when made by CZ of Czechoslovakia.) And the CZ grip fits most hands better. Try a true CZ sometime. You'll be impressed. (You may still prefer your P-226, but that's OK.)
