Out of the longer barrel of an M1 carbine, the .30 carbine round does compare favorably with the .357 or many other handgun rounds fired from a handgun length barrel...which should really come as no surprise. The M1 carbine was in many ways, the first “PDW,” designed for those personnel who would have normally been issued a sidearm only (i.e. mechanics, mortar crews, cooks, etc.)
I shoot my dad’s M1 and love it. I’m trying to find a Mini30 to try out for myself. In any case, the Mini14 would put on a serious hurt and ruin someone’s day.
