History
Adopted by the Austro-Hungarian Army in 1898 for the Rast-Gasser M1898 revolver. The revolver and cartridge equipped Austro-Hungarian officers through the entirety of WWI and remained in use into WWII. The M1898 is notable for being a solid-frame revolver with a gate-loading cylinder — a design considered obsolete by most nations in 1898 but retained by Austria-Hungary for cost reasons. Rast-Gasser revolvers and original ammunition are common collector items.
