Abstract

Abstract A firearm safety apparatus and method of using same are disclosed. The apparatus comprises a sleeve formed of a flexible plastic material capable of being flexed from a normal position to a flexed position to surroundingly receive an associated firearm and spring urged lever means for locking the hammer of the associated firearm in the uncocked position. The sleeve has front and rear ends, the rear end being open to receive the associated firearm and the front end having an aperture to receive the barrel of the associated firearm. The spring urged lever means includes a lever arm rotatably mounted within the sleeve by a pivot pin. In the operative position, a spring urges the end portion of the lever arm downwardly to engage the hammer of the associated firearm, thereby locking the hammer in the uncocked position.
