But if I were starting out with a revolver and looking to not spend a fortune I'd start with the GP100.
It's pretty hard to argue it. They don't really drop much resale value either. They hit a certain level and stay there or go up with inflation adjusting unless you butcher one.
Trigger, yeah, the Smith is better but you can get a pretty nice pull on the Ruger modular design.
I wouldn't hesitate to buy a used Ruger. With a used Smith and Wesson I'd probably be a bit more thorough checking it out.
For a 6 shot .357, the Ruger Six family, GP100 or a Smith 686 are the solid buys for an introduction.
If you want a 5 shot snub in .357, the SP101 is honestly the perfect option for all around awesome.
It's got enough heft to not punish you with full Magnum loads yet not heavy enough to be uncomfortable for most to carry all day.
If you want a .38, it's hard to beat an all steel J frame of whatever particular flavor you'd like.
I need to get myself a nice model 36 so I can dress like Joe Friday.
