Abstract
A loading indicator for use in a firearm having a barrel including a rear section and a cartridge chamber is disclosed. In one example, the loading indicator includes an elastic shaft disposed within a compartment in the rear section of the barrel and a feeler portion coupled to the elastic shaft, wherein the elastic shaft is loaded to cause the feeler portion to project into the cartridge chamber and wherein the loading of the elastic shaft allows the feeler portion to be displaced when a cartridge is placed into the cartridge chamber. The example implementation further includes an indicator element adjacent the feeler portion and coupled to the elastic shaft, wherein the indicator element projects from the cartridge chamber when the feeler portion is displaced by a cartridge.
