Does anyone shoot a titanium S&W revolver in .45 Colt or .44 Mag?

[Brant Buster]

If so, how do you like your piece? I'm looking at purchasing a light-weight grizzly / black bear gun in .45 Colt or .44 Rem Mag, and the lightweight qualities of these Smith & Wessons (M325 or M329) are mighty appealing for carry purposes.

I realize the M325 is made in .45 ACP, but a competent pistol smith ought to be able to replace the cylinder with a CM or stainless steel one in .45 Colt.

Please respond if you might shoot the M625 or M629 Mountain Guns in these chamberings.

Corbon offers some very impressive loads for both cartridges.

Thanks in advance.
