I agree with Whiskey, don't scrimp on the mount. Buy the best you can get, I feel that is more important than the type of scope you put on it. Kinda like the foundation of a house... if the foundation isn't stable, everything above it will also be unstable. I personally have SSK's mounts on most of my handguns. I've never seen the mounts from Weigand but if they are a heavy weaver style and use multiple screws to hold it on then it's probably a good one. I haven't seen a clamp on mount hold up on anything over a long period of time. Mine has been on for a number of years and I use full power loads for hunting and silhouette and it's had thousands of rounds thru it and has never moved. I kinda prefer a dot out to 125 or 150 yards but everyone is different. I use a scope for my really long range shooting but that is always from a sandbag or creedmore position.
There is a pic of my Super Blackhawk with the SSK mount and dot on the Ruger Forum site under the favorite Rugers thread.
