I haven't but have looked into one of these..
It requires the hammer be changed to one they supply, I assume it gives clearance for the bolt type allen pin used..
I also thought that the allen bolt could be turned down & a piece of viton rubber slid over it creating a bolt buffer similar to the ones used in the 10/22
Never tried it YET..
It would require that the top pin be driven out of the mainspring housing & the new screw recepticle be pinned into it, No big deal with the right punch & a vise to hold it while driving it out, You could also use a board with a hole drilled in it to allow the pin to come out..
Thiokol it's me HEADKNOCKER from the S&W Forum..
