Thanks for the leads, guys. I don't mind going custom, if I have to, but first want to check out any "on-the-shelf" options.
CJ - Bianchi makes a holster for th 3" J-frame. I have one for my 3" Model 60 (adjustable sight) .357 Mag. I think it's model 5B - a tan leather belt holster with a safety strap.
