My favorite, if I had to pick one, is the 1911 chambered in 9mm. I have a Springfield Armory stainless "loaded" and love the way it shoots. Only modification is I switched the 2 piece guide rod for a GI so I don't need an allen wrench to field strip it. Cheap ammo and easy shooting chambered in 9mm as the piece is heavy and recoil is low. I have carpal tunnel as well as arthritis so this greatly improved my accuracy.
