ABSTRACT:
A lock for a firearm is operable to engage and disengage a draw bar or trigger bar of the firearm, which connects the trigger to the hammer. The lock includes a lock member which, in the locked position, operatively engages the draw bar to move the draw bar out of engagement with the hammer. The firearm is thereby rendered inoperative. The lock member, in the unlocked position, permits the draw bar to engage the hammer in the usual manner to permit operation of the firearm. The lock member can be provided as part of a lock assembly which can be readily installed in the firearm, and in a construction which is resistant to tampering.
