I voted for the Colt merely because that's what I want.
Nothing in particular against Sig, just like Colts. But, none have shown up around here yet & only 'net purchases I'll make on pistols is thru Davidson's. Only place I've even heard about having them is Gun Broker & asking up to $100 over MSRP. I'm gonna give it until my birthday in May, then guess I'll get the Sig.
