John M. Browning invented both the Model 1911 pistol and the 380 ACP cartridge. Whether he ever intended to pair the two we'll never know for sure. The Browning 1911-380 isn't a full size 1911, it's built to approximately 85% of the scale of the original 1911 pistol chambered in 45 ACP. The 1911-380 is a faithful replica, fulfilling the sense of duty to the original and copiously tested to ensure accuracy, function and the feel you should expect from a pistol bearing the Browning name.
