The CZ 100 is a semi-automatic handgun, introduced in 1995 by Česká Zbrojovka .

It is identical in most ways, except for adjustable sights, trigger and firing mechanism work, and cleaner machining of the main slide and exterior steel.

It is hammerless DAO (double action only), meaning that the firing system is under no tension unless the trigger is pulled.

It is constructed for one-handed cocking, with a protrusion on the slide behind the ejection port intended for pushing against the edge of a fixed surface.

The tactical rail allows for the attachment of a laser or light, but only proprietary models.
