Locking magazine

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 locking mechanism 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.

2. The magazine according to claim 1 wherein the block element is operable to prevent extraction of the lock from the magazine well when the locking mechanism is in the locked condition.

3. The magazine according to claim 1 wherein 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 second rotational position different than the first rotational position.

4. The magazine according to claim 1 including an elongated shaft having a first end connected to the locking mechanism and an opposed second end connected to the block element.

5. The magazine according to claim 4 , wherein the elongated shaft is a straight element.

6. The magazine according to claim 4 , wherein the elongated shaft is a cylindrical element.

7. The magazine according to claim 4 , wherein the elongated shaft has a circular cross section.

8. The magazine according to claim 4 , wherein the opposed second end of the elongated shaft is proximate an upper end of the elongated body.

9. The magazine according to claim 4 , wherein the opposed second end of the elongated shaft is closer to an upper end of the elongated body than to a lower end of the elongated body.

10. The magazine according to claim 4 , wherein the elongated body defines a shaft passage receiving the elongated shaft.

11. The magazine according to claim 4 , wherein the elongated body has opposed sidewalls, a front wall, and a rear wall, and wherein the elongated shaft is proximate to one of the opposed sidewalls and to the front wall.

12. The magazine according to claim 4 , wherein the elongated body has opposed sidewalls, a front wall, and a rear wall, and wherein the elongated shaft is proximate to the rear wall.

13. The magazine according to claim 4 , wherein the elongated body has an exterior profile adapted to be closely received in a firearm magazine well, and wherein the block element is within the exterior profile to enable extraction of the lock when in the second position and protrudes from the exterior profile to prevent extraction of the lock when in the first position.

14. The magazine according to claim 4 , wherein the block element is an elongated element extending away from the elongated shaft.

15. The magazine according to claim 4 , wherein the block element is a planar element having a major surface flush with an external surface of the elongated body when the block element is in the second position.

16. The magazine according to claim 4 , wherein the block element extends laterally from the elongated shaft.

17. The magazine according to claim 4 , wherein the block element extends radially from the elongated shaft.

18. The magazine according to claim 4 , wherein the block element extends transversely from the elongated shaft.

19. The magazine according to claim 4 , wherein the block element extends perpendicularly from the elongated shaft.

20. The magazine according to claim 4 , wherein the block element defines a block passage receiving the elongated shaft.
