I Have This Old Gun - Johnson Spitfire Carbine
This video explores the Melvin Johnson Spitfire Carbine, a unique firearm developed by Melvin "Mater" Johnson. It details the design philosophy behind the 5.7x33mm MMJ cartridge, an attempt to create a small-caliber, high-velocity round by necking down the .30 caliber carbine cartridge. The video highlights Johnson's ambition to offer an enhanced M1 Carbine platform to the US Military, which ultimately competed with the development of the AR-15. Despite its innovative nature and impressive ballistics for its time, the Spitfire Carbine did not achieve widespread adoption, remaining a historical curiosity.
