I want a Colt Commander with no frills in SS. I DONT want an aluminum frame. How do I know I am getting one. I know the Colt Combat Commander was what the steel frame Commanders used to go by. Are the Colt Commanders steel frame now and the "light weight" Commanders the aluiminum frame models? I am gonna have one ordered by my dealer most likely and just want to make sure to get it right... TIA.
