I'm a 1911 guy ...so the Sig 220 doesn't make it for me ...Wilson Combat 1911's on the other hand ...are some of the finest 1911's / and .45 acp's I've ever owned. But the 220's have their fans - and I'm not saying they're bad guns.
All of the 226 lineup of guns are fine guns ...and I don't know how you can pick a bad one. Personally I favor the all stainless versions in the .226 lineup like the current Elite Stainless. I have a pair of the older all stainless versions of the 226 - one in 9mm and one in .40S&W with DA/SA triggers - adn they're both very good guns. The triggers on the Sigs are not a 1911 finely tuned trigger -- but in Single Action, I'm effective enough with a 226 or even a 239 ...that carrying it is always an option for me...
I would go with one of the 226's ...but I can't really pick among the 2 models ...
Here are my 226's / I'm very happy with them both ( the gun with the wood grips is a 226 X-Five - its a different beast / way too heavy to carry / but a fun gun to have as well ).
