Firearm safety and security device

A device for locking a firearm that extends through a firearm's muzzle and chamber, wherein said firearm utilizes said chamber for receiving a round of ammunition in axial alignment with a firearm's barrel, said device comprising:

• a) a receiving cartridge with exterior dimensions similar to said round of ammunition for said firearm's chamber, wherein said receiving cartridge will have a tubular forward end contiguous with a recessed tine receiving area for engagement of a locking and unlocking means;
• b) an elongated tubular rod dimensioned to fully occupy said firearm's barrel and extend from said firearm's muzzle into said firearm's chamber, located on said elongated tubular rod will be an adaptor means for permanently coupling said elongated tubular rod to an adapted common use locking means, opposite said elongated tubular rod will be a plurality of reflexive locking detent tines to function as a distal locking means with said recessed detent tine receiving area, each of said reflexive locking detent tines having a bore bar forward shoulder to engage said elongated tubular rod and a large diameter bulge to engage said recessed detent tine receiving area;
• c) an actuating rod axially positioned through said elongated tubular rod and through said adapted common use locking means while having a lock engaging portion positioned inside said adapted common use locking means so as to provide said locking and unlocking means by distal transmission between said adapted common use locking means and said reflexive locking detent tines and;
• d) said adapted common use locking means permanently abutted to said elongated tubular rod, whereby when said device is installed and locked in said firearm it will fully occupy said firearm's chamber and said firearm's barrel so as to prvide a means of assuring that said firearm is not loaded and cannot be loaded until said device is unlocked and removed from said firearm.
