Definitely the Redhawk. I love mine and you can't go wrong with a Ruger. I don't need to think about the GP because my Redhawk is a .357, but since they're scarce the GP-100 would be a great choice if that were your caliber decision. There are .41 and .44 Redhawks out there too if you want to spread your calibers. Aw heck, just buy everything you can.
