I have a Sig Carry Elite, as well as a full sized Sig 1911 "style" handgun. I agree that the price point of the Sig is above what you indicate the use of the gun will be. Many times I've fired a friends Rock Island Armory 1911, with a 4" inch barrel, and it functions just fine. The RIA also costs about half what the Sig does.
The Sigs are good shooters, and nice to look at, but as posted, for your stated intentions, I wouldn't spend the extra money.
