Tex, You actually tried to fit CT grips for a model 10 S&W on a Taurus Model 80? What where the issues with the fit? The Model 80 looks so much like a S&W Model 10 it makes one wonder. How much modification would it take?
No, I tried to fit a Pachmayr off my model 10 to my M66. Part of the problem is the location of the screw, leaf spring vs coil, just different. Never tried the M80. Both are square butts and might could have worked, but for the screw location. Hell, I really wanted a Hogue on it anyway, LOL.
