I'm thinking of going back to school to become a sheriff deputy. I was reading over some info on the course I found on the net and noticed some guns they mentioned. They were 9mm, 40, 45 semi autos and .38 Special and .357mag revolvers. Now I like revolvers, especially big ones. I own a Ruger SRH in .454 Casull so recoil doesnt bother me. I'm wondering now, if I would get a revolver in .357 mag, which would be the best for this type of thing? What about barrel length, etc? The course doesnt begin until September so I figured I'd get the gun soon and get good with it. Even if I would decide not to go through with the course then I'd still have a cool revolver
