Conan,
Is that the "Schwarzeneger Conan", or the "Robert E. Howard Conan"?
I've never shot the 245, but I've held one in the shop. I'd say that if it measures up to the standard set by the rest of the Sig line, you can't go wrong. One reviewer in a gun rag said that it was very accurate and a separate review said it was very inaccurate w/most loads. That was unusual considering that most Sigs I've heard of shoot under 3" at 25 yds. Some, like a 225 I'll be spending some time w/next weekend, goes into 1" at 30yds.
Anyway, if I were you, I'd consider the way that I'd be carrying it. If ITWB, I'd ask the shop owner if he'd let me put it in my waist band and sit on one of his chairs. That w/let you know if the width is too much or sharp edges, etc. If you want the best double action/single action handgun made I don't think you'll make a mistake. If you want a single action, go w/a Glock or 1911 copy. Hope this helps.
