For a moderm SA/DA revolver?
S&W has a VERY reputable name, but they are pricing themselves out of business.
Ruger makes(in my opinion) one of the best revolvers out there, the GP100.
Taurus is making a very strong name for themselves, and have some really cool features you wont find in any other manufacture, like the hi-cap cylinders.
(so are their lesser counterparts, Rossi)
Those are the only three names I would consider buying a revolver from.
