That's a nice looking Revolver. You can spend more money on a revolver, but you can't really go wrong on a Ruger.
On the subject of first revolvers, I'll tell you an amazing story! My first revolver was an Iver Johnson 5 shot 38 special. It was one of those guns that worked its way through the family 2 or 3 times. My father owned it at least once. As I recall, he was the original owner.
Anyhow, at one point during his ownership he was carrying it on the last day of deer season. We spotted a big old baron doe on the ridge opposite the draw from us. This was a NICE deer, about the size of a good 3 point buck, and she's walking broadside about 150 yards out. NO SWEAT! Easy shot for the old man and his 30-30 Savage . I don't remember why but for some reason his rifle would not function. By Oregon law I could not carry since my tag was already filled. Out of shear desperation the old man pulled that Iver Johnson, looked at me, and I just shrugged. He leaned on an old snag and fired. I'll be damned if that big ole doe didn't drop dead in her tacks. Got her right through the heart and lungs. That's a true story, and a pistol shot that could probably never be duplicated.
