Yes, I have had a Sig 1911. I don't own it now, not because of any problem, but because I trade a lot, and often regret a lot. That SIG was one I regret letting go of. Anyway, I think SIG makes very good pistols (I have a SIG P229R in 9mm) despite the purists disdain for the external extractor (S&W also uses an external extractor.) The good thing about 1911s is that there is a lot of aftermarket parts for them, and you can use other brand magazines and not just SIG brand, which tend to be very expensive...but then, what isn't these days? I prefer to use Wilson ETMs in my 1911s.
