Locking magazine

Abstract

A magazine is provided for a firearm. The magazine comprises a locking mechanism. The locking mechanism has a user interface adapted to enable a user to select between a locked condition and an unlocked condition. The locking mechanism has a rotor movable between a first rotational position when the locking mechanism is in the locked condition and a second rotational position when the locking mechanism is in the unlocked condition. The magazine comprises an elongated shaft connected to the rotor. The magazine comprises a block element connected to the elongated shaft. The block element is adapted to move between a first position when the locking mechanism is in the locked condition in which at least one of firearm operation and magazine extraction are prevented, and a second position when the locking mechanism is in the unlocked condition in which firearm operation and magazine extraction are enabled.

         1 . A magazine for a pistol having a magazine well, a slide operable to reciprocate between a forward battery position and a rear loading position, and a barrel with a barrel block movable with respect to the slide between an elevated engaged condition in which the barrel prevents movement of the slide to the rear loading position and a lowered disengaged position in which movement of the slide to the rear loading position is enabled, the magazine comprising:
 an elongated body configured to be closely and removably received in the magazine well;   the elongated body defining an ammunition passage configured to receive a supply of ammunition;   the elongated body having feed lips at an upper end configured to retain the supply of ammunition;   a restriction facility connected to the elongated body and having a locked condition and an unlocked condition;   a follower within the ammunition passage;   the locking mechanism being below the follower;   the locking mechanism having a user interface operable to enable a user to select between the locked condition and the unlocked condition;   a block element operably connected to the locking mechanism; and   the block element operable to move between a first position when the locking mechanism is in the locked condition in which movement of a firearm trigger is prevented, and a second position when the locking mechanism is in the unlocked condition in which movement of the trigger is enabled.
