Variants 

• G23: standard model appeared in 1991.
• G23C: the letter C indicates that the weapon is equipped with a compensator which reduces the bearing of the weapon when firing. The compensator is composed of two orifices on the top of the breech (at the front of the weapon) and of holes on the top of the barrel in order to allow the gases produced during the combustion of the powder contained in the barrel to escape.

Evolution

All G23s sold from 1998 on have a carcass fitted with a molded accessory rail and featuring an anatomical grip. In 2010, the fourth generation G23 / G23C appeared with an interchangeable back of butt (3 sizes).
