i would get a 44 and shoot it for a while. if i got to the piont where i could shoot that very well but wanted more power but more recoil i would step up to the 454 casuall or the 480 ruger. but i would just stick with the 44 it's a good cartridge handgun or rifle(i have a win. 94 trapper in it)(my hog gun).

about the 500 i really don't see the point. yeah it's the most powerful handgun in the world but why carry a handgun that weighs just as much as a rifle and you would have more power with the rifle.
