Both my father and my uncle served in WWII, my dad in the PTO and my uncle in the ETO. My dad was enlisted, carried an M1 Garand until he was promoted to Sgt., at which time he switched to an M1 Carbine. My uncle was an infantry officer, carried an M1 Garand on Utah Beach, later switched to a Thompson SMG and, while recuperating from injuries and wounds, was a REMF with an M1 Carbine.
The M1 Carbine was designed as a substitute for a handgun for officers and non-coms...it was not intended to be a battle rifle. Both my dad and uncle suggested that, if you had to bet your life on your rifle, a Garand was a good, albeit heavy, bet. I have four Garands, two M1As and an AR15A2 and I'm a paper puncher (in the USAF, my issue weapon was a S&W .38 Spl)...but if I had to pick one rifle to bet my life on, it would be one of my Garands.
