This pistol is in very good condition with few handling/use marks. The barrel is ported near the muzzle, which is not found on the 9mm version. It comes with 1 magazine, but not its original box. The CZ 100 has a number of important handgun features. It is hammerless DAO (double action only), meaning that the firing system is under no tension unless the trigger is pulled. There is an automatic firing pin safety device. 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 gun uses the usual Browning cam for action. It was the first of CZs weapons to use synthetic materials.
