L-Frame Conversion???

    Just an idea. I like the .40 S&W round. I like the L-Frame. I've been looking at the .40 S&W and the L-Frame and wondering. I understand that folks have set the L-Frame up in .44 Special. I was wondering if I could set up a L-Frame in .40 S&W. The idea I have is to use a 686. Have the cylinder and chamber line bored, then throated, etc. for 180 gr. bullets. Have the back of the cylinder faced off to allow the use of moon clips. If it could be cut for 10mm, so much the better as I could then fire either round. Is this a workable idea? If so, who would be a good gunsmith to contact for the work. If there is a particular -# of the 686 to use, please state so and why. Sincerely. Bruce.

    What you are asking for has already been made by Smith & Wesson. It's called a Model 646.

    Thank you. I was just doing some shooting with my 686 and thinking what could be done with the L Frame. Thought a L Frame in .40 S&W or even 10mm (shoot both 10mm and .40 S&W) would be a lot of fun. Hadn't heard of the 646.

    Its a bigger frame, but i prefer the 610 to the 646, especially if you want to shoot 10mm.
