The pistol was produced in .25 ACP|, .32 ACP|, and
Kurz variants, all of which used
blowback as their operating mechanism. Although not expensive, at the time it was of advanced design and high quality construction with relatively few parts, well sealed against dirt. Metal components were
forged or
machined, and assembly in general made no use of
screws, even securing the wooden grips with a spring-loaded metal fastener inside the magazine well, although some examples do incorporate a single screw for that purpose. The hammerless action depended on a spring-loaded
striker to fire the
cartridge. As in early
Colt and
Browning pocket pistols, the Ortgies striker also operated as an ejector as the
slide traveled backwards after discharge. Unusual design features included the
safety and the
magazine. The safety was a lever inset into the back of the grip and, with the gun cocked, forced backward out of the grip into the "safe" position by spring tension from the firing pin upon depression of a button under the slide. Thus, engaging the safety simultaneously reduced tension on the firing pin spring. To disengage the safety, a shooter simply would squeeze the grip, pressing the lever forward and locking it flush with the back of the frame. At least the earlier Ortgies magazines could accommodate both 7.65mm (aka .32 ACP) and Kurz, (aka .380 ACP) ammunition and were interchangeable between pistols of either calibre. One side of the magazine was marked for and featured seven holes showing the positions that cartridges of that size would occupy when loaded; the other side had similar holes and markings for cartridges. Modern replacement magazines are purpose-built for one caliber only. ==Production==
