I recently inherited a Smith and Wesson Model 19-4 .357 Magnum when my father passed away. I got the gun but no papers what-so-ever. Anyone know where I can located/download a field-stripping guide for this weapon? I have scoured the S&W site but can only find a generic revolver owners manual with no field-stripping info at all. It has not been well cared for and I really want to get it back into shape. Any help is appreciated!!! Thanks!
