I like Pachmeyr Presentations, and I've got big hands too.
Jerry Miculek actually recommends holding the big boomers lower so that they can twist back some.

That grip is at the end of the first video.
I've asked myself the same questions about old cops, but I asked about how they could hold the old Registered Magnum in the 30's
I found that if I used the old fashioned one hand grip, I could stand the recoil a lot better.
I decided that the problem with big hands is that are generally attached to big arms and a big body, so that we can force the hands to absorb most of the recoil, rather than having the arm flex. I've even seen little guys have their bodies knocked back some by shooting .44 magnums. Doesn't happen with me.
So maybe the advice of leaving your elbows a little loose is good too, though I've never tried it.
