I just don't like how the titanium cylinders look, especially with a stainless steel frame and barrel. I don't mind it quite as much with a black frame, like a M-329.

I continue to toy with the idea of buying a stainless 6 shot .357 L frame cylinder and having it rechambered to .40 S&W and fit to my M-646, so it is a uniform color.

Or mebbe I just ought to sell my -646. I've never shot it.
