Quite a few years ago, I sent a Ruger Bkackhawk cylinder to DougGuy to perform his magic with his Sunnen hone and general expertise. This past July, he did it again. I sent him another cylinder that was having serious accuracy problems. Once again, a very satisfied customer. His price is right, his turnaround time is great and, most of all, his communications with me was excellent.... HIGHLY RECOMMENDED.
