Andreas Schwarzlose (best known for his 1907 and 07/12 machine guns) designed this pistol for military and civilian use, and it saw minor commercial success. The blow-forward action was pretty much a developmental dead end, because it made for unusually sharp recoil and was potentially unsafe to handle – the only three commercially available pistols made this way were the Hino, the Schwarzlose, and the Mannlicher 1894 (which was quickly replaced by better Mannlicher designs). The Swiss did tinker a bit with a blow-forward action in their AK-52/53 rifle as well, but this ultimately went nowhere.
