I have touchagunwantagun syndrome its pretty painful, there is a cure but I can't afford it lol The Scorpion carry 1911 is at the top of my list, settled for a SA XDs so I got .45 power for half the cost.
Can't speak for the other models, but I picked up a pair of sig 1911XO nitron models for $750ea ($1500 for the consecutive serial #'d pair) & absolutely love them. Its one of tbose "why didn't I buy them sooner" things.
My opinion is that you can't go wrong with a sig 1911!!!
