I am making the up grade from my glock 22 to the 1911. about time I know. So I need the advice of people in the know. what are the pros and cons of aluminum frames against stainless steel. I have been looking at the Pro Carry HD II Kimber. I'm thinking this because of the stainless frame. I am only getting on shot at the gun I have dreamed of and have a limited budget. Any and all comments will help. Thanks guys.
