A .25 ACP caliber (6.35mm) version was introduced in January 1914, which collectors now call the model 1910/14. It was produced through 1917, and featured a nine-round magazine. END QUOTE.

John: Model 1910 was in 6.35mm (25 ACP) and the 1914 was 32 ACP (7.65mm). the first 1910s were the 'sidelatch' variation that you describe, and the first 1914s were the 'humpback' variation. The 1910, 6.35mm, and the 1914, 7.65mm, stayed in production until the apppearance of the 1934 with its more ergonomic grip. Some 1914s were accepted into German service: they have a military acceptance mark in front ofthe rear sight, and many have the Prussian Eagle stamp, usually on the front of the trigger guard.

The reference on these pistols is Roy Pender's "Mauser Pocket Pistols". I'm aware of at least one more book on them in preparation.

A friend of mine collects these things. The upper left pistol in the first picture is a sidelatch Model 1910 in 6.35mm. The upper left pistol in the second picture is a humpback Model 1914 in 7.65mm.
