Well, not sure if this is the right spot to put this... but it is on a Smith.
What's the word on the 686 conversion by TK Custom... the one so you can fire 9mm in the 686 (as in 9mm Luger, 9x23, 38 Super...) by using moon clips.
I picked up a 686 recently and have been thinking about having the conversion done (or at least get a cylinder and/or cylinder crane to convert back and forth)
I don't have any first hand knowledge of the work, but a 9x23 would be a great round to shoot. Also you could use 9mm Luger for cheap shooting. I have a S&W 547 which is a 9mm "K" frame. 9mm is a great revovler round oddly enough. The 547 doesn't need clips, as it uses a special extractor, but my M1917 uses moon clips and I've always thought they were a decent idea as well. They are fast to reload and fit fine in speed-loaded pouches. There are even holders specifically made for them now that so many competitors are using wheel-guns with them now.
If you think it would be something you like, I say do it.
