I'm a big 1911 fan - but I think you'll be happy with the Sig as well.
I'm not a big fan of the Sig double action guns ( or anyone's double action guns for that matter ) - but I really like the Sig 226 XFive in a single action. But like others probably told you - you can get "thinner" grips for a 1911 as well and that may be the trick for your wife.
I have a Kimber Tactical pro - 4" barrel - 1911 model in 9mm that seems to suit my wife - and some of the kids pretty well. It's a little lighter - alloy frame - and shoots pretty well in a 4" barrel. Not everyone wants a .45 ACP for a first gun ......
