Hey guys just killed my first hog with my ruger blackhawk 50th aniversary flattop 44mag. Called weaver to get the scop mount for it that didn't have to have the flat top drilled and tapped. But they said theirs only works for the regular blackhawk. Do anyone of you know a manufacture who makes mounts like this, if not thats fine. How many of you know some good mounts where you have to drill and tap the flattop, not just the standard blackhawk? If so when you take the mounts off does it weaken the fram of the gun with the holes in the top strap. Thanks guys for any help
