Yeah, by the sounds of it (getting many new handguns on 21st birthday and the arsenal of rifles you already own) get yourself a Promethius. Knock yourself out!
What's a Pormethius?
He could get a .357 Mag Desert Eagle. Anything bigger than that is too scary to shoot, my dad has fired the .44 Mag. version, and he said your hand shakes too much to actually aim, and my uncle tried the .50 and he said it wasn't fun, he said it was more like hanging on for dear life!
