NOT intended to anger or even annoy:
I do not care for either, at all. The current level of detail & care shipping from Sig has me soured, and I don't care for their P-series original design guns in the first place.
Kimber hasn't impressed me ever, beyond the pure beauty of their handguns. I don't care for their firing pin lock, don't care for the reputation of their customer service and I don't believe they make guns that match their price range.
Were I given a choice between the two, it's a darn tough call. I'd take whichever I knew I could sell. If I were forced to keep, I'd take the design of the gun I prefer (the Kimber) but I wouldn't care for it.
If I had to use it for full-blown WAR, I'd take the Sig, I suppose.
