The sight radius does limit its accuracy, and I do have a nice revolver with 4 inch barrel, but this is the one that feels just right. Maybe that also helps accuracy.
I have one. I've shot it at 25 yds and I think a 3" group is doable. Probably my favorite revolver and I have 4 other Smiths. Bought it from someone on this forum but I can't remember who it was.
