The last time I had a scoped handgun was with a small diameter Bushnell handgun scope with the built in rail mount in the 70's. I ended up buying some handgun mounts along with a box of gunparts at an estate sale. There was a mount for a Ruger single action in there. So I used it on this Ruger Bisley 41 mag with a Simmons 2-6 power. An excuse to shoot it again anyway.
