The cartridge indicator is a rod slidably mounted in a cavity in the breech slide of a firearm to allow checking for the presence of a cartridge in the chamber. The rod has a check end which protrudes out of the breech slide as biased by a spring at the chamber end of the rod in the cavity. The chamber end of the rod has attached a chamber pin which slides in a pin cavity in the breech slide. When the check end is pushed into the breech slide by the user, if the chamber has no cartridge, the chamber pin moves into the chamber and the check end is pushed into the breech slide thereby indicating an empty chamber. If the chamber pin encounters a cartridge, the check end can not be pushed into the breech slide.
