Own a Sig 226 and a CZ TS which is very similar to the shadow. Both shoot very well. In my view the bore axis is not as big deal, you adjust to this sort of thing. The CZ is heavier and somewhat easier to shoot well as it is more intended to be a target/competition firearm while the 226 is more a combat firearm. If you go with the SIG get the SRT trigger. I love both of them but can typically shoot the CZ a bit more accurately although the 226 is plenty accurate and unbelievable reliable. Both are great firearms can't go wrong with either.
