In use with the Austrian Army concurrently with the 7.63mm Broomhandle, the Red Nine name comes from the field practice of deeply branding a "9" into the grips; even in low-visibility situations, a soldier could know what ammunition to load just by taking hold of the pistol. Blade front and tangent rear sights graduated to 500 meters with the three-line Oberndorf address on top of the chamber, "crown/crown/U" commercial and "crown/gothic letter" military proofs on either side, two-line address on the right side of the frame, a New Safety hammer and niter blue small parts. The grips are in the 24-groove configuration with the branded and red-filled "9" on each side. Included with the pistol is a holster stock rig consisting of a brown leather carrier marked "C.HOLSTE&Co/MUNCHEN/1916", a hardwood stock numbered "639" on the mounting iron, and a wood handled bright steel cleaning rod.
