The CZ999 and the EZ9 are almost identical to the CZ99, however they are redesigned to be more ergonomic. Most parts will interchange between the newer and older designs, but some parts, like the grip panels, will not.
CZ999 Scorpion The CZ999 Scorpion () is an updated variant of the CZ99 with some improvements, such as a slimmer grip and redesigned grip panels, wider slide serrations, a serrated backstrap, standard 3-dot sights, a curved trigger, a square trigger guard and a longer hammer spur. While initially intended for the 9×19mm, there is a variant of the CZ99 chambered in
.40 S&W, primarily for foreign importers, with many of these handguns imported by the US in 1990. Over time though, newer versions of this firearm have been developed: The Zastava CZ999, with DAO and DA/SA selector, as well as the CZ999 Scorpion without this selector. Also features a loaded chamber indicator. Comes in compact model as well.
Zastava EZ Fourth generation CZ99. It is the same as the CZ999, however it has an under-barrel
picatinny rail for mounting lights and accessories and a larger ring hammer. Service- and personal defence gun, single/double action, ambidextrous. The CZ999 and EZ9 do accept standard CZ99 magazines, but they will not accept all CZ99 parts, such as grip panels. Also like the CZ999, the EZ9 exists in two calibers. There are compact versions of both calibers.
KSN Golan Israeli clone of the CZ99, with rights being purchased after Zastava halted production. Though the Golan lacks the CZ99's loaded chamber indicator and has a shorter slide and barrel, different grips, and other minor cosmetic variations from the CZ99, it is virtually identical in internal design, and some parts are interchangeable between the two.
Tressitu TZ99 South African clone of the CZ99. In the early 1990s South African company Tressitu entered into a licensing agreement with Crvena Zastava to produce a licensed copy named the TZ99, offered in both 9×19mm and .40 S&W. The TZ99 was only produced for a short period before the company went out of business in the mid-1990s. A number of TZ99s stored from the dissolution were imported to the US in the mid-2000s. == Adoption ==
