Abstract

A firearm locking mechanism comprising block or body having a conventional pin-tumbler or cylindrical lock mounted generally vertically therein. The block or body is received within the exposed area between the breech and open breech block in a firearm directly above the magazine, with an engagement member connected to the bottom of the lock being received within the top of the magazine and rotated by the lock. The engagement member engages beneath and between the cartridge-retaining surfaces at the top of the magazine to secure the lock and body to the top of the magazine, thereby preventing the breech block from closing or the magazine from being removed. The locking mechanism similarly prevents moving the firing pin assembly into proximity with any cartridge remaining in the barrel or magazine.

A firearm locking mechanism for use with a firearm having a breech and a magazine, said magazine having an end disposed proximate to said breech, said end of said magazine being at least partially exposed when said breech is in an open position, said firearm locking mechanism comprising:

a body, at least a portion of said body being selectively disposed within the breech of the firearm when the breech is in the open position;
a locking mechanism, said locking mechanism being connected to said body and selectively movable between an unlocked position and a locked position;
and
an engagement member, said engagement member being operatively connected to said locking mechanism and disposed such that said engagement member engages the end of the magazine when said body is disposed within the breech of the firearm and said locking mechanism is in said locked position and such that said engagement member does not engage the end of the magazine when said locking mechanism is in said unlocked position,
whereby the body blocks the breech in the open position and prevents the firearm from being discharged and the locking mechanism and engagement member prevent the body from being removed from the breech and the magazine from being removed from the firearm when the locking mechanism is in the locked position.
