I have shot several Kimber 1911's, both in .45 & 9mm and liked them all just don't like a one year warranty If a pistol is that good, why not stand behind it.
I have also shot a lot of Sigs in various calibers and models including the Scorpion (its good to work at a LGS/Range). Have liked all the classic style (read steel) Sigs and own several, P239, 226, wifey's 239 and my everday carry 1911 SS Carry in 45ACP.
All reliable and don't remember the last FTF from any of them.
Gee, I guess if I was making the choice, I would go with the Sig. JMHO & YMMV
