I agonized over this just 13-14 months ago and the replys were much the same.
Went with the drill & tap using the Weigand mount and have had no problems with it. I really don't like the idea that there is now a couple of holes in the top strap of the Super but yet will probably never sell this gun and use it for special purpose (read the late season) when longer shots can be possible on the bunched up deer.
I'm actually in the same situation as you were months back. I have a new (used) 6" Dan Wesson 44 VH. I LOVE the gun with open sights but would really like to mount my new (used) Leupold M8 2X on it, too. I would LIKE the option to use the open sights on it someday need be. I'm looking at either the Weigand (drill/tap) mount or the B-Square (clamp-on) mount. If I go with Weigand, I would also get a 20% discount on the rings from Weigand, too, PLUS, I can get three rings without having to buy FOUR rings at a store ,lol.
I have some questions.....
First, with a drill and tap installation, could I feasibly take the scope off later and unscrew the mount (and just reinstall the mount screws in the receiver/shroud) or is it preferred NOT to remove the mount screws and mount once initially installed?
Second, is the drill and tap install THAT much stronger than a clamp on?
Third, is lapping something you recommend on ALL handgun installs? (I've never lapped and never had a problem on a rifle before).
Fourth, I'm nervous about having someone DRILL my gun. I don't have any gunsmiths I know or frequently use. Does anyone know someone in St Louis, MO or a resource to FIND such a person?
Thanks in advance for your responses.
