The Schouboe automatic pistol (pronounced sko-bo) is a Danish pistol.
The Schouboe pistol was designed by Jens Schouboe, better known for his work on the Madsen light machine gun. The pistol was originally manufactured in .32 ACP in 1903; Schouboe later adapted his pistol to chamber .45 caliber rounds when he decided to participate in the 1907 US Pistol & Revolver Trials. The pistol was not successful and was quickly dropped before it even entered the trials; it was also submitted to the UK for trials, where it was (predictably) also unsuccessful. Production for the pistol stopped by 1917 when World War I hit; less than 1000 were made for both pistols. The highest known serial number for the Model 1907 is 524, and serial numbers 1 – 100 are prototypes.
The Schouboe is a simple blowback pistol with a non-exposed hammer. The Model 1903 is unique in that it has a magazine disconnect, where a second latch could be manipulated to disconnect the magazine; this allowed the 1903 to act as a single shot pistol while holding the magazine in reserve.
The Model 1903 used the common .32 ACP round, while the Model 1907 used the far less common 11.35mm Schouboe, also known as the .45 Schouboe. Very little is known about this bullet.
