Grrrr I was JUST about to post this haha. I've never actually held or fired a gun before, and I don't think I ever will, but the M1 Garand is a beautiful piece of Americana. It's too bad that it has to exist at all, but what can you do. If I were to purchase a gun it would be an M1 Garand.
As for a pistol, I'd like to add the Colt Single Action Army revolver (I guess it's not technically a pistol, but whatevs)
Classic.
