Nicknamed for the machined grooves that serve to cycle and lock the cylinder, this is an improved break-open version of the 1878 with a star extractor. While sturdy and well-made, the "Zig Zag" was discontinued in favor of the 1896 'Broomhandle' semi-automatic pistol, though some are known to have been carried by participants in the First World War. Blade front and notch rear sights, with the top of the barrel rib marked "GEBR.MAUSER&Cie OBERNDORF a/N. WURTTEMBERG.1878." and a vented cutout above the cylinder. A safety switch is installed on the left side of the barrel lug, which interfaces with the cylinder and locks out the release latch on the front. Fitted with checkered grips.

Good as replated with 85% of the chrome plating. Showing areas of light to moderate pitting under the chrome surface, general handling marks and some lightly discolored areas. The grips are fine with general handling marks, light tool marks around the screws, and a few heavier indentations around the butt. Mechanically very good.
