1. Field of Invention
This invention relates to firearms and more particularly to an Adjustable and Removable Trigger assembly for improved firearm safety and storage.
2. Description of Related Art
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.
Browning, Beretta, and other firearms manufacturers have used various adjustable trigger designs utilizing set screws to lock the trigger shoe in position.
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.
FIG. 1 is a perspective view of the Adjustable and Removable Trigger. This illustrates the major components of the invention and highlights the Ball lock access hole 2B that gives access to release the Ball lock when one wishes to remove the trigger assembly from the gun.
FIG. 2 is a cut-away view of the Adjustable and Removable Trigger. This illustration shows how the Ball Lock parts hold the Removable assembly in place on the firearm. The separate view of the Trigger Housing without any parts details the various holes and pockets for components.
FIG. 3 is an exploded view of the Adjustable and Removable Trigger parts. The Removable Assembly is shown to illustrate the full assembly that removes from the gun when the Ball Lock is released.

The main parts of the Adjustable and Removable Trigger are illustrated in FIG. 1's perspective view. These parts are 1 the Trigger housing, the Removable assembly comprised of 2A the Removable trigger base, 2B the Ball lock access hole, 2C the Trigger shoe, and 2D the two Adjustment set screws.
The functionality of this invention is more fully illustrated in FIG. 2's cut-away view of the Adjustable & 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 2A, the Trigger Shoe 2C, and the two Adjustment set screws 2D. The Removable assembly 2 can be adjusted by loosening the two Adjustment set screws 2D and moving the Trigger shoe 2C to the desired position and then tightening the Adjustment set screws 2D to fix the position. This adjustment can be made with the Removable assembly in or out of the gun.
The Removable assembly 2 inserts into the Trigger housing pocket for the Removable assembly 1A and snaps into position by momentarily raising the Ball lock ball 3C and once the Removable assembly is seated in the pocket the form of the Removable trigger base 2A allows the Ball lock ball 3C under pressure from the Ball lock spring 3B to reposition so that the Ball lock ball 3C locks the Removable trigger base 2A into position along with the whole Removable assembly 2.
Detachment of the Removable assembly 2 is accomplished by inserting the same L-shaped Allen wrench used to tighten the Adjustment set screws 2D into the Ball lock access hole 2B and passing through the Trigger housing hole for access to release the ball lock 1B and pushing up the Ball lock ball 3C while rotating the Removable assembly 2 down and out.
The ball lock parts are located in the Trigger housing 1. The Ball lock ball 3C is located in the Trigger housing hole for the ball lock spring & ball 1C. It is held there under light tension by the Ball lock spring 3B which is held in the hole by the Ball lock set screw 3A which threads into the Trigger housing threaded hole for said screw 1D.
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's aesthetics.
