WWII production Underwood M1 Carbine converted to 5.7 mm Johnson Spitfire. Includes two magazines, 69 rounds of ammunition and 16 brass casings. Please feel free to contact me if you have any questions.
Short history: The first thing we need to know is the creator of this caliber, "MMJ" Melvin Maynard Johnson Jr. He was commissioned into the Marine Corps Reserve in 1933 as a Second Lieutenant and completed Harvard Law School in 1934. Johnson designed the M1941 Johnson rifle, the Johnson Light Machine Gun and the M1947 Johnson auto carbine. So clearly he was a man that understood the dynamics of weapons design.
In 1963 he founded his Johnson Arms, Inc business. Developing models that utilized the M1 Carbine chambered in his creation the Johnson MMJ 5.7mm Spitfire. He also offered barrels chambered in that caliber for converting any M1 Carbine by replacing the barrel with modifications of the feed ramp. Johnson advertised this new smaller caliber and the modified carbine as a survival rifle being light, fast handling with a low recoil.
So what was this new caliber all about? The cartridge is based on the .30 Carbine that was necked-down to .22 caliber. With that the Johnson MMJ 5.7mm Spitfire A.K.A. 22 Spitfire, 5.7mm Johnson or 5.7mm MMJ American wildcat cartridge was born.
