Due to the lack of a barrel, the revolver's effective range is very limited. Since its component parts can be folded inward towards the cylinder, it is easily concealable inside a pocket. It was common to leave an empty chamber with no cartridge under the hammer, as the weapon has no trigger guard or safety catch. The weapon cannot be aimed accurately because of its lack of front and rear sights and very short barrel. Despite its limited potential, the revolver was effective at extremely close range. For reloading, the cartridge cylinder must be removed, refilled, and replaced.
The revolver also has a design constraint when opening the barrel, by default the barrel points back towards the wearer of the knuckles. For this, the user then has to remove the knuckles, rotate the gun to point forward to the target and then shoot. Certain defense scenarios might not accord the liberty of time to do such an involved maneuver.
A 9×19mm Parabellum revolver of similar design (but no official designation) was allegedly used by British Commandos during World War II, though exact statistics about production numbers and technical details have as yet remained undisclosed to the public.
