The huge Montenegrin model is how most remember the Gasser name, but there were smallbore Gassers, too.
Two members of the Austrian Cisleithanischen Gendarmerie posed in 1915. The policeman on the left is wearing a holstered Gasser M.1885 Gendarmerie-Revolver.
The M.1885 Kipplaufrevolver or 2nd Model Montenegrin was a hinged-frame, top-break design that used a locking system similar to the British Webley-Pryse.
Pressing in the levers on either side unlatched the barrel to allow loading and unloading. It's probably not the ideal system for operating with one hand.

The Rast & Gasser Infanterie-Revolver M.98 was used by the Austro-Hungarian army from 1898 until 1919. The steep grip to frame angle makes it very recognizable.
The M.98 used a frame-mounted, spring-loaded firing pin. This is one of the earlier instances of this design, which has become the rule in most revolvers.
The ejector rod was supported by an full length guide rod under the barrel. Note how the loading gate is rotated 90 degrees to the rear for loading or unloading.
The M.98's hinged sideplate could be opened for cleaning and/or repairs. This was not an uncommon feature on military revolvers during the late 19th century.

A band of Yugoslav Chetnik partisans, posing in 1942, is well equipped with ZB26 machine guns, grenades, Mauser rifles and at least one Model 1898 Rast-Gasser.
A detachment of Greek monks fighting against Bulgaria in 1913 counted on Mannlicher and Gras rifles, along with M.98 and 2nd Model Montenegrin revolvers.
