## Claims

### Claim 1

A magazine for a firearm having a frame defining a magazine well and having a trigger having a range of motion between a forward released position and a rearward discharge position, the magazine comprising:
a body adapted to be closely and removably received in the magazine well; and
a locking element connected to the body;
the locking element being movable between a retracted position and an extended position;
wherein the locking element has a protrusion adapted to enable movement of the trigger to the rearward discharge position and to enable extraction of the magazine from the magazine well when in the retracted position; and
wherein the protrusion faces the trigger and prevents movement of the trigger to the rearward discharge position and to prevent extraction of the magazine from the magazine well when in the extended position.
