S&W has used those "cross slotted" barrels many times. It's nothing new. Pacrossbow, Weigand Combat "Magnum" rings would also be my 1st try. I use use them on a Mod 83. They're thinner than most.
BINGO,
Thanks for the information.
I looked at Weigand Rings and there is one issue. For the 44 MAG they recommend three rings.
The distance between the scope mount cutouts isn't far enough to use three rings. Basically the adjustment dials are too big to fit between two rings next to each other (I made two drawings to show what I am referring to below).
I heard back from Smith & Wesson and they stated that Warne rings will work (they even sell them on their website).
I have a set of Warne's on the way and received another set of rings that work as well (a gentleman on another message board sent me them).
Thanks again everyone for all the help, I appreciate it.
