Not so far as I'm aware, just 2" and 4" versions, but I'm often surprised to learn of oddball runs for distributors such as Lew Horton. In my limited experience, I thought the 2" sight radius was inadequate for adequately accurate aiming ... I looked at one of the new 5" 63's the other day, and it's really sweet, but my 10 round 617 is sweeter!
I've got a M18-4 4" with which I'm very comfortable and confident. I'm just not wanting to carry that anymore. Several years ago it went back to S&W for a sticky chamber and timing. They re-blued it out of the goodness of their heart. It used to be in the field with me in "desert" canyons while fishing in Idaho - now I'm in IL and it goes only to the range.
Thanks for the links, I may have to wait for this one - M63. I want something that gives me a sight picture I'm used to and I'm not sure the 43C can come through on that on - radius is a bit small also - although if the radius were short enough, then everything would be of equal blur.
I have a 650 which is a 3" round-butt J-frame in 22 Magnum, vintage circa 1983 or '84. I like the gun but think an identical one in .22LR would be real sweet and much more versatile.
