Magazine for a firearm including a self-contained ammunition counting and indicating system

摘要

An ammunition clip or magazine for a firearm including a self-contained system for sensing the amount of ammunition contained within the magazine and visually or audibly indicating that value to the user of the firearm. The counting and indicator system may be configured to display the number of rounds remaining in the magazine itself, or the number of rounds remaining in the firearm overall (the number of ammunition rounds in the magazine plus one round in the chamber of the firearm, if applicable), or it may be configured to simply indicate that the magazine is empty or that the number of rounds remaining in the magazine is below some other predetermined threshold. The magazine may be utilized in conjunction with any suitable firearm without modifying the firearm.
