I have a stainless smith 1911 with the black grips, two magazines, and the box. It is in very good shape and I am the second owner. I am thinking that it is slightly large and heavy for an every day gun. I was thinking about trading it in for a 4 inch 1911 or an m and p 340. What would be a fair trade in value for the gun if I traded it to a shop. How much would it be worth in a trade in towards an m and p 340 from a private person? Btw this is a steel frame with the 3 dot novaks.
