.45ACP . . . a great round out of a handgun . . . and devastating coming out of that longer barrel.
Today the big, fat .45ACP is obsolete as a sub round . . . and many are going to the 9mm in the super-hot NATO loading for subguns. They are small in diameter and lots can be loaded into big clips.
Still . . . there's something nostalgic about a tommy gun and a 50 round drum!
Here's my father-in-law, in WWII. His job was the tommy gunner on the bridge. His job was to both guard the bridge in port . . . plus use his tommy gun when the fighting got real close to an enemy boat that they might capture or have to get close to . . . closer than the deck guns to shoot at. The Germans were full of tricks.
He got a Purple Heart in one battle from shrapnel while on post, and ended up using his Thompson, with deadly effect, on enemy sailors in battle . . . when they WERE up close and personal.
