I have been thinking (and reviewing) the M2 versus the M1928M1. The M2 seems to supersede the M1928M1 after 30 yards, period. The .45 ACP seems to "run out of gas" in short order. At 100 yards, the 110 grain pill still carries the energy of the .357 S&W Magnum (1602 fps) the Soft Point ammunition plays a large part in this, but I doubt if a .45 ACP at 100 yards can even come close.

Besides, it is easier to pack 30 rounds of .30 Carbine than it is to carry 30 rounds of .45 ACP of any kind.

No, the M2 wins this "shootout".
