Mr. Weingarten probably knows the answer, I can’t wait for his response, but I would bet the leading purchase would be a 9 MM. handgun. You know, the kind the FJB said could “blow out a lung.”
The 9MM was laughed at in the 1930s, even though the bullet is the same size of a .38 spl. The .45 ACP was the “romp’em and stomp’em” cartridge for everyone.
Now everyone wants a 9mm. I still have my old St Louis Browning Hi-power.
