I'll also say that given the choice between .357 and 10mm in the same size revolver with the same capacities (Ruger still makes 6 shot .357 GP's along with the 7) I think that the 10mm is the better for defense against men and beast. 135 grain 10mm loads are nothing short of superb on paper easily beating .357 in power, but being able to launch 220 grain hardcast bullets beats anything the .357 can possibly do.
I don't think that the extra round of .357 will make much difference if you're forced to shoot at a charging bear or other large animal, but honestly if given the option, I would rather have a Glock 20 if I was out in the wild.
It goes against my sig, but revolvers are heavy and Glocks aren't.
I've been thinking about getting a 10mm Glock for a while with the intention of handloading my ammo to save money, but with this new revolver, I think I may get this before I get a 10mm Glock because I won't have to pick up my brass, I can play with my 10mm loads, and because I have three other guns in .40 S&W, so I'll always have ammo to shoot in this 10mm revolver.
It serves no real purpose other than a range gun and maybe another gun to keep hidden around the house, but so far Ruger's got me interested, which is more than I can say about the 10mm Super Redhawk.
