Since Sig primarily makes other pistols, the management didn't deem the Sig 1911 worthy of its own section, so we get lumped into the Sig section in "Other Semiauto Pistols."
I have two.
My Ultra Carry is the most reliable pistol I've ever owned...well, I guess with the exception of my Encore pistol...
And it's the best looking pistol I ever owned too.
I like the external extractor. It just works. A lot of the bad rap for external extractors was due to the aborted attempt by Kimber at putting external extractors on their 1911s, which were way too short to be effective.
BTW, my DW has an external extractor too. It just works, too.
