My Dad lives out in Idaho as I've mentioned before.
Well, he needed a new rear sight for his Ruger Single Six convertible and asked me for a source.
The only place I knew of out there was Tactical Solutions, since they did so much with the Ruger Semi Auto .22's I figured they might be able to help him out.
He had a VA appointment yesterday in Boise so he stopped in, no luck.
But he found another place in Boise that had the whole assembly, and installed it while he waited. Total ? $40
Run by a fellow Marine, it carries new and used guns, and has a gun smith on site.
Dad is happy as a pig in sh!t, and says they are great people.
