I swapped out the grip screw bushings to slim grip bushings in preparation for the slim cocobolo double diamond grips. I used Permatex red threadlocker to secure them in place.
I'm considering a stainless steel mainsping housing. I do not own any 1911s other than the New agent that still have a polymer housing installed. I'm actually thinking about swapping them both. I wish a reasonably priced aluminum housing were available for the stubby Officer's Model. The decision would be easy then.
