A while back, I bought a Colt Commander from Chuck Rogers. It was built for a friend on Chuck's, while it was nearly perfect for me, the previous owner had a arched MSH installed. Chuck expertly modified the heel of the frame and the MSH to what he called a "round butt" treatment. This is a very slight rounding of the lower corner of the frame and housing. I decided a flap MSH would suit my shooting style and grip a tad better. I ordered a blued MSH and blended as per the pics below. It was then polished & cold blued. Any thoughts,........? As received from Chuck with the arched MSH.
