Trying to decide between the Sig 1911 Extreme or Springfield Loaded Parkerized. Both have night sights and ambidextrous safeties which are important to me. Other than the rail on the Sig (and $150 more on the price), I'm really not sure how different they are. If anyone has experience with either or both of these your input is greatly appreciated. If anyone knows any reason to avoid one or the other, i.e. reliability, customer service, parts, that would be appreciated as well. Since I bought my Delta Elite I've really caught the 1911 bug. I'd buy both if I could but that's just not in the budget.
