The FN Model 1903 was a self-loading semi-automatic pistol engineered by John Browning and made by Belgian arms manufacturer Fabrique Nationale. It was introduced in 1903 and fired the 9×20mmSR Browning Long cartridge. The FN Model 1903 is based on the same mechanical design as the Colt Model 1903 Pocket Hammerless, which Browning sold to both companies, but enlarged to handle the more powerful 9mm Browning Long cartridge. Due to its reliability, accuracy, light weight, and quick reloading, the M1903 was an issued sidearm for many police forces and militaries.
"A Belgian-made semi-automatic pistol adopted by a number of nations, including Sweden."
— In-game description
The Mle 1903 is a weapon featured in Battlefield 1. The main advantage of the Mle 1903 compared to the M1911 is its higher rate of fire (360 compared to 300). However, the pistol suffers lower damage per shot.
Among the sidearms available to all classes, it offers the lowest recoil and the quickest draw time, but the longest full reload time.
It is similar to the 1903 Hammerless, but unlike the 1903 Hammerless "pocket pistol" abilities, uses the same weapon style as that of larger pistols, like the M1911.
The Mle 1903 Extended is a carbine variant of the standard pistol introduced in the Battlefield 1: They Shall Not Pass expansion. It is equipped with an extended magazine for more ammunition and a stock for more control compared to the base weapon. It is unlocked by obtaining 75 kills with the Mark V Landship.
