Anyway to mount a scope on a Blackhawk or super
black, 3 screw, WITHOUT drilling????

B Square makes a base that uses the rear sight screw hole and barrel clamps. Weaver also makes one.
The problem I had with the Weaver was the barrel clamp would mar the barrel from recoil. I tried shim stock under the clamps but it cut the brass.
I don't know if it is a problem with the B Square.

Thanks for the info.
