Pahoo & Buckeye,
I've got the same one. 3.5" with the birds head grip.
I bought it as a sort of emergency kit gun. . . It just sits in a bag year after year and the bag goes with me camping and whatnot.
It's not as good of a shooter as the single six in my experience. But with CCI mini mags I can achieve acceptable groups. I think I would have no problem hitting a rabbit at 15 yards, maybe even 20.
Mine did shoot very high when I got it, so I filled down the front sight and then finished it off with a cold blue pen, and now it shoots right to the point of aim, perfect left to right and elevation.
I haven't put a lot of rounds through it, but I trust it, and for being such a neat little gun (mine came with the .22 mag cylinder as well) and only costing something like $150-170ish?, I think it would be hard to say I could have done better.
I am very pleased with mine and think they are all a great value no matter what configuration you choose.
Of course id take a single six or a Ruger bearcat over the heritage rough rider any day if Money was of no concern.
However, Ruger doesn't make any of those with the more concealable and pocket/packed away friendly birds head grip... and the all around size of the 3.5" birds head rough rider is really why I choose it over anything else. Then taking into account its low price and poor finish (not worried about keeping it nice), its just about the perfect survival/emergency .22 handgun.
