I've got a fairly short mental list of guns that EVERYBODY should have at least one of.
Up towards the top is: 4" double action 357 magnum with adjustable sights.
Personally I'm a sucker for pinned and recessed S&W model 19's--but there is
nothing wrong with a Ruger or Dan Wesson, or even a Taurus if you get a good one.
Shoot it with cowboy 38's for plinkin' and training the kids, 38 special for general
target shooting, and 357 for hunting and serious social situations. Treat it right,
and someday in the future some kid is going to get a kick out of shooting
grandpa's old revolver.
