At the Rock Island Auction on 24 June they sold a 5 1/2” heavy barrel model 41 with a compensator. I know there’s nothing impossible when collecting anything from S&W but this is a variation I’ve never heard of. It appears that the muzzle has been machined to fit the comp and the barrel drilled & tapped for the retaining screw. The comp would be put into the machined recess and secured with the screw. Could this be a factory made option or is it a aftermarket change? Any help is welcome.
