BACKGROUND  
       [0001]     1. Field of Invention  
         [0002]     This invention relates to firearms and more particularly to an Adjustable and Removable Trigger assembly for improved firearm safety and storage.  
         [0003]     2. Description of Related Art  
         [0004]     In the past firearm manufacturers used various adjustable trigger designs and external locks for gun safety. Firearms have used various adjustable trigger designs for sometime, but the mechanisms have always relied on an additional external trigger lock to achieve both adjustable and secure functionality.  
         [0005]     Browning, Beretta, and other firearms manufacturers have used various adjustable trigger designs utilizing set screws to lock the trigger shoe in position.  
         [0006]     These trigger locks are generally bulky, two-piece clam shell designs that come into the trigger area from both sides of the trigger guard and engage the lock thereby blocking the trigger from access and use. In displaying the gun the trigger lock is very utilitarian and detracts from the aesthetics of the gun, but does serve its role of preventing unauthorized use of the firearm.

       DETAILED DESCRIPTION OF THE INVENTION  
       [0024]     The main parts of the Adjustable and Removable Trigger are illustrated in  FIG. 1 &#39;s perspective view. These parts are  1  the Trigger housing, the Removable assembly comprised of  2 A the Removable trigger base,  2 B the Ball lock access hole,  2 C the Trigger shoe, and  2 D the two Adjustment set screws.  
         [0025]     The functionality of this invention is more fully illustrated in  FIG. 2 &#39;s cut-away view of the Adjustable &amp; Removable Trigger,  FIG. 3A  is an exploded view of the Adjustable and Removable Trigger parts and  FIG. 3B  is an illustration of the Removable Assembly. The Removable assembly  2  is comprised of the Removable Trigger Base  2 A, the Trigger Shoe  2 C, and the two Adjustment set screws  2 D. The Removable assembly  2  can be adjusted by loosening the two Adjustment set screws  2 D and moving the Trigger shoe  2 C to the desired position and then tightening the Adjustment set screws  2 D to fix the position. This adjustment can be made with the Removable assembly in or out of the gun.  
         [0026]     The Removable assembly  2  inserts into the Trigger housing pocket for the Removable assembly  1 A and snaps into position by momentarily raising the Ball lock ball  3 C and once the Removable assembly is seated in the pocket the form of the Removable trigger base  2 A allows the Ball lock ball  3 C under pressure from the Ball lock spring  3 B to reposition so that the Ball lock ball  3 C locks the Removable trigger base  2 A into position along with the whole Removable assembly  2 .  
         [0027]     Detachment of the Removable assembly  2  is accomplished by inserting the same L-shaped Allen wrench used to tighten the Adjustment set screws  2 D into the Ball lock access hole  2 B and passing through the Trigger housing hole for access to release the ball lock  1 B and pushing up the Ball lock ball  3 C while rotating the Removable assembly  2  down and out.  
         [0028]     The ball lock parts are located in the Trigger housing  1 . The Ball lock ball  3 C is located in the Trigger housing hole for the ball lock spring &amp; ball  1 C. It is held there under light tension by the Ball lock spring  3 B which is held in the hole by the Ball lock set screw  3 A which threads into the Trigger housing threaded hole for said screw  1 D.  
         [0029]     Adjustment, removal and placement of the Removable assembly is effortless, an effective deterrent to unauthorized use of the firearm and does not detract from the gun&#39;s aesthetics.
