I've shot both, and to me they shoot the same. The CZ already has night sights installed, so that doesn't add or detract that when comparing it to the Sig. Any reason that I should pick one over the other?
I have the chance to buy either one (and, no, not the funds to buy both, before someone puts that little girl meme up. LOL).
