Introduced in 1910 with fixed sights, the 2-line address/patent dates on the slide, Belgian proofs, and checkered "FN" grips. The pistol includes a Japanese style brown leather and pigskin flap holster. The holster has two steel suspension loops on the back and a replacement magazine for a 7.65mm Sauer pocket pistol in a front pouch. Officers in the Japanese military privately purchased their own sidearms, with Browning patent pocket pistols being a popular option. Some Japanese purchased FN 1910 pistols are known to have a Kanji mark, with reported examples in the 369000-456000 serial range, with commercial examples outside of that serial range and without the Kanji mark, as on this example, known to also be possible Japanese purchased pistols.
