Modified firearms for firing simulated ammunition
First Claim
1. A handheld firearm for firing simulated ammunition, said firearm comprising a barrel having a cartridge chamber formed at one end thereof, and a pressure safety system adapted for preventing the successful completion of a firing cycle of live ammunition, said safety system comprising a pressure relief port formed through the wall of said chamber and arranged to align with the wall of a live cartridge located in the chamber of said firearm, said port being of sufficient diameter to allow a portion of the wall of a cartridge fired in said chamber to be expelled through said port, and said port communicating with a discharge channel system arranged to divert and disperse gases from a fired cartridge therethrough.

Abstract
The present invention discloses a firearms safety system for adapting conventional handheld firearms to fire non-deadly simulated training ammunition, which system provides a series of gas relief ports and passages to prevent the successful firing of live ammunition in the firearm. The system can be advantageously utilized in modified M16 type military type rifles which have been previously adapted to fire pistol cartridges such as the 9 mm and .40 S&W calibers.
