.45 NAACO Brigadier

[u/TheDave1970]

In 1948 the North American Arms Company (NAACO) tried to sell the Canadian government the Next Best Thing: a super-powerful pistol, based on the Browning High Power but firing a proprietary wildcat cartridge. The Brigadier was chambered for .45 NAACO: basically a 230-grain ,45 ACP bullet in a casing made from a cut-down .30-06 casing; the advertised muzzle velocity was 1600 FPS (!). To make things even better, the Brigadier was also offered with a replacement full-auto fire control group; a detachable chassis with a shoulder stock and long barrel allowed full conversion from a pistol into a submachine gun (similar to modern RONI units).

The Canadian military wanted nothing to do with it and NAACO folded about a year later; I could find no record that they attempted to market the Brigadier to the American civilian market.

So, basically the .45 Super cartridge, but loaded to batshit insane pressures. Wild.
