The Redhawk has a reputation involving a slightly weird trigger that's not easy to tune. It uses one spring for both the trigger return and something else, I forget which...point is, lightening the trigger return spring is a basic gunsmith trigger job trick and you have to be a lot more carefull about that part with the Redhawk.
In the 48state area, if the threats are black bear and cougar and maybe a boar now and then, you can get the job done with a 6" GP100 and heavy-loaded .357. Something to think about, anyhow.
There's been lots of talk about how the .45LC has advantages over the .44Mag. The .45LC has more case volume and can therefore work at less pressure for the same ballistic job. Go look at the product line for Buffalo Bore ammo at
www.buffalobore.com to get some examples...the .45LC+P 325grain at 1,300fps is unmatched among more or less any available .44Mag, with the exception of Garrett's "Redhawk/SuperRedhawk ONLY .44Mag+P" monsters.
I personally think the ultimate DA woods gun would be the Ruger SRH in .454, barrel chopped to 5", Tritium front sight using the Ashley pre-dovetailed mount they sell, rear sight same as what works on the GP100, Express with a vertical bar. Shoot it mostly in .45LC/.45LC+P, and pack some genuine .454 "just in case" I really needed it (not likely, but what the hell).
But I'd pack a Vaquero Bisley in .45LC first...much lighter, handles recoil well even one-handed, fast as hell on the first shot, decent follow-up if you're willing to master the SA.
