Sharp early version of the S&W Model 629 .44 Magnum Mountain Revolver.   From 1989, it has all the early model features - roll markings on the barrel instead of etching, vapor blasted satin finish, flash chromed trigger & hammer, and more rounded chamfer on the cylinder front (than later versions.  Comes with a nice set of Ahrends grips, but if you prefer I will swap them for standard Hogue finger groove rubber grips that came on later versions of the 629 Mountain Guns.
