Rotary action firearm safety assembly operable with finger on the trigger

This invention provides a readily accessible easily manipulatable improved safety assembly for a firearm that can be easily retrofit on many existing firearms without special modification or adaption. By providing rotary action from a finger actuated safety lever operable with a trigger finger maintained adjacent the trigger, a rifle or shotgun may be easily moved without awkwardness from safe to fire condition in a moment of excitement when game or a moving target appears with less chance of awkwardness or an aborted shot. The safety assembly provides in a lateral bore through the trigger guard cage adjacent to and rearward of the pivoted trigger a rotatable barrel like member blocking rearward trigger motion in one detented position and permitting the trigger to move and release the firing pin in a second detented position where a receptacle cavity in the barrel mates with a trigger extension finger and lets the trigger pivot. A rotating lever is thus placed in a position where it can be actuated by a middle finger with the trigger finger in place and the firearm being readied for a shot.
