A magazine safety for a firearm comprise a sleeve (40) that is slidably received within a recessed pocket formed in the magazine well and urged downward into the pocket by a spring. The sleeve has an upper blocking projection (44) that engages a notch (22) in the trigger bar (20) of the firearm to prevent lateral movement of the trigger bar and a lower engaging projection that extends into the magazine (72) well and engages the magazine once it is fully inserted, thereby lifting the sleeve and its blocking projection free of the notch of the trigger bar. When not lifted by the magazine against the urging of the spring (60), the blocking projection prevents movement of the trigger bar. Since the trigger bar is incapable of movement, the firearm cannot be fired until a magazine is inserted.
