[QUOTE=steamloco76;139603460]I've scoped quite a few of my S&W revolvers, all of which came factory drilled and tapped for the mounts. I've replaced the Weaver bases on my harder kicking revolvers with the dual dovetail Leupold bases and rings. The Leupold bases look better and the ring design eliminates the two screws most likely to loosen from recoil.

The Raptor mount has 3 screws, not 2, I am sure for that very reason and I would find it very hard to swallow that 3 set screws would come loose with any amount of recoil, this thing is set a rock solid.

I use buffalo bore which has much greater pressures than regular ammo and so far no issues.
