The ČZ handgun models 50 and 70 are available to Western collectors today but were both developed and produced behind the Iron Curtain. In the years since the release of his Cold War Pistols of Czechoslovakia, author James D. Brown has continued his research and amassed significantly more information on this category of arms, especially the Models 50 and 70. These pistols were designed and produced for the Czech police by Česká zbrojovka, better known as "ČZ," one of the oldest and most important firearms manufacturers in the world. This new illustrated reference describes the production history, markings, operation, performance, maintenance, and accessories of the ČZ 50 and ČZ 70.
