A pistol including a loaded chamber indicator to identify the presence of a cartridge loaded in the firing chamber. The pistol may generally include a barrel, a receiver attached to the barrel thereby defining a barrel-receiver assembly, and a chamber associated with the barrel-receiver assembly. An indicating element is provided which in one embodiment may be pivotally mounted in the barrel-receiver assembly. The indicating element is displaceable in response to contact by the cartridge from a first position which may in one embodiment correspond to an absence of a cartridge loaded in the chamber, to a second position which may in one embodiment correspond to a presence of a cartridge loaded in the chamber. A biasing member, such as a spring, may be provided to bias the indicating element towards the first position. In one embodiment, the indicating element protrudes outwards from the exterior of the pistol in response to contact by the cartridge rim to provide a visual and tactile indication of a loaded chamber condition to a user of the pistol.
