Don't mean to sidetrack the thread, but I just got back from the range, and tested that WEIG-A-TINNY mount for my SBH hunter and my matchdot, and it holds a perfect zero, and shoots 1 hole groups at 25 yards off from a sandbag. It looks awesome, too. The stock 30mm ruger mounts just were not far enough apart to fit a matchdot in between them, a couple more mm, and the stock rings would have worked. The WEIG-A-TINNY mount is better, anyway, it gives a lot more mounting options.
.41 magnum forever!
Maybe I'll try it at the 50 yard range tomorrow.
Another thing to think about is the distance between the rings.

Looking at the weaver mount, you can clearly see there's only 2 possible mounting locations, now assuming the hold down bolts are fairly centered there isn't a lot of adjustment as far as what red dots it works with.
I got the weigh-a-tinny mount for my SBH hunter because of the versatility.

Look at the mounting options available. 2, 3, or 4 rings mounted where you want them. It's pretty slick, if you have a hunter model. I use 2 rings because the matchdot takes a lot of space between rings, but the rings I used were 6 screw rings, and are really solidly built.
If you got a 7 1/2" model (That's the length of the 'hunter' model.)
Is it a hunter model? If it is, it will be stamped 'hunter' on the top strap.
If so, I'd so get the weigh-a-tinny mount, just because of the versatility.
What red dot are you thinking about?
