Abstract
A handheld training pistol specifically designed to train the user to anticipate the transition from double-action to single-action experienced when shooting most semi-automatic pistols. The training pistol includes a blocking bar (19) that prevents full forward movement of the reset mechanism, causing the training pistol to simulate a single-action trigger pull. The training pistol further includes a decocking system that allows the user to transition the training pistol back to the double-action or starting position. The training pistol is made of some type of brightly colored plastic with weighted inserts to provide a realistic training device.
Description




BACKGROUND




1. Field of Invention




This invention relates to safer firearms training, specifically for shooters to develop the correct muscle memory to anticipate the transition from double-action to single-action experienced when shooting most semi-automatic firearms.




2. Description of Prior Art




As long as there have been firearms, shooters have been searching the best way to increase their accuracy in using them. For Law Enforcement Officers, their lives could depend on their ability to quickly hit their target with speed and accuracy. The simplest and most cost effective method has always been to “Dry-fire,” or practice shooting with an unloaded gun. The user simply chooses a suitable target, holds the firearm in a standard shooting position, lines up the front and rear sights, and practices pulling the trigger while keeping the sights fixed on the previously chosen target. This helps develop the correct hand and eye coordination, as well as the muscle memory to correctly pull the trigger smoothly rearward while keeping the sights fixed on the target. All of this greatly benefits the shooter when actually loading and firing the weapon.




Among the problems related to dry firing is the damage it does to the firing pin on expensive firearms. Continually pulling the trigger and allowing the firing pin to slam into an empty chamber will eventually cause it to malfunction when the shooter needs it most.




Another problem when dry-firing using an unloaded semi-automatic pistol, is that the pistol will not reset the itself into single-action after the first trigger pull, the way it does when a bullet is fired from it. It remains in double-action after each trigger pull, causing the user to develop the incorrect muscle memory. The user will become used to a complete release of the trigger each time. When the user then actually fires his loaded semi-automatic pistol, the pistol resets into single-action, or “cocks” itself after the first trigger pull as it loads the next bullet into the chamber. The shooter who has dry fired repeatedly in double-action and developed the incorrect muscle memory will pull too far and too hard against very little resistance, causing the gun barrel to move and the sights to become misaligned. The bullet will then miss it's target.




Based upon the patent search and research conducted, there is no other product or invention, patented or otherwise, that has been developed to allow shooters to safely dry fire without the use of an actual unloaded firearm. There has more certainly been no other product that allows the user to build the correct muscle memory to anticipate the trigger transition from double-action to single-action when firing a semi-automatic handgun.




SUMMARY




The present invention is a handheld training pistol that will simulate the trigger transition from double-action to single-action, experienced when firing an actual semi-automatic pistol.




Objects and Advantages




In addition to the objects and advantages previously described, several objects and advantages are:




(a) to provide safe, inexpensive shooting training that can be conducting in the user's own home. The present invention fires no projectile so there is no danger of damage or injury to anyone;




(b) to allow dry firing without the inherent dangers of unloading and reloading firearms in the home;




(c) to cause the user to develop the muscle memory to anticipate the transition from double-action to single-action;




(d) to save the user the danger and cost of using live ammunition, while allowing for quality shooting training;




(e) to allow the user to stop damaging expensive firearms in order to improve shooting accuracy;




While the present invention is made to be the basic size and shape of a standard six-inch semi-automatic pistol, it is constructed from a brightly colored plastic to prevent it from ever being mistaken for an actual firearm This is an important aspect of the invention as it further provides the safest firearms training possible.




The invention further contains two cavities, which will be filled with lead, or some other heavy material in order to provide the user with the approximate weight of an average firearm. Again this is done to provide the safest, most realistic training possible.

DESCRIPTION—FIGS.


1


THROUGH


11






The majority of this handheld training pistol is constructed of brightly colored plastic except when otherwise noted, such as the lead inserts, rubber band


26


, ball chain


23


or springs


3


,


24


,


25


. Molded into the right side housing


1


(

FIGS. 1-2

) are the majority of accessories needed to complete assembly. Along the forward or barrel section and in the lower or grip section are rectangular cavities


2


that will contain lead or some other high density material, to add weight to the training pistol which will provide a realistic feel.




The trigger


17


to the pistol is inserted along the trigger grooves


11


and trigger guide


8


. This combination will keep the trigger


17


in place as it is pulled rearward against the forward pressure caused by the main spring


24


and return spring


25


. The snapper


18


is affixed to the top of the trigger


17


by means of the rubber band


26


. The rubber band


26


is first hooked over the trigger post


27


, then pushed through the rubber band hole


28


in the snapper


18


, and again hooked over the trigger post


27


in the opposite direction (FIG.


7


). This will keep moderate pressure between the snapper


18


and trigger


17


causing the pistol to reset itself after each trigger pull.




The main spring


24


is affixed to the right side housing


1


on the main spring post


12


located above the front of the trigger grooves


11


. The opposite end of the main spring


24


is attached to the front of the snapper


18


. This will cause the snapper


18


to move forward each time it moves upward on the snapper ramp


7


sufficiently enough to lose contact with the trigger


17


. The length of the main spring


24


is sufficient that when it is completely constricted, the trigger


17


will be able to move forward past the rear of the snapper


18


allowing the snapper to move downward and rest the pistol.




The trigger


17


is caused to move forward by the return spring


25


. The return spring


25


is affixed to the right side housing


1


at the return spring post


13


located under the rear of the trigger grooves


11


. The return spring


25


will cause continuous moderate pressure on the trigger


17


, even as the blocking bar


19


interrupts the pressure from the main spring


24


.




The blocking bar


19


is a lever located just above the snapper


18


, which is attached to the right and left side housing


1


at the blocking bar mounting lug


4


and rotates slightly as it is forced downward by means of a torsion spring


3


connected to the torsion spring ledge


29


on the rear of the blocking bar


19


. This rotational movement is depicted in

FIGS. 8 and 9

, as clockwise. The blocking bar


19


can be rotated upward or counterclockwise by means of rotating the decocker


21


counterclockwise thereby pulling the ball chain


23


downward, conversely providing lift to the blocking bar


19


(FIG.


10


).





FIG. 8

illustrates the training pistol in the staring or double-action position. As the trigger


17


on the training pistol is pulled rearward, the connection between the trigger


17


and the snapper


18


will cause the snapper


18


to glide rearward, and the main spring


24


to expand. The snapper


18


will continue to glide rearward as it makes contact with the snapper ramp


7


and begins to slide upward and rearward along same. At one point, however, the snapper ramp


7


will cause the snapper


18


to rise sufficiently to cause it to lose contact with the rear portion of the trigger


17


. It is at this point that the main spring


24


will constrict and pull the snapper


18


forward, releasing the trigger resistance caused by the main spring


24


and giving the user the sensation that a shot has been fired. It is then that the blocking bar


19


, which is under slight but constant clockwise pressure from the torsion spring


3


that contacts with both the blocking bar


19


and right side housing


1


(

FIGS. 1

,


1




a


, and


8


), will rotate downward into the notch molded into the top of the snapper


18


, preventing it from full forward movement (FIG.


9


). Since the trigger


17


is free to move completely forward, but when moving rearward will not encounter the resistance provided by the snapper


18


and main spring


24


until the trigger pull is nearly complete, this position provides the user with the sensation of a single-action or “cocked” pistol The training pistol will reset itself in this position after each successive trigger pull until the blocking bar


19


is pulled upward allowing the main spring


24


to fully constrict and pull the snapper


18


to it's most forward position (FIG.


10


). In order to accomplish this, the decocker


21


must be utilized.




There is a rectangular slot molded throughout the center of the decocker


21


. The left and right decocking levers


20


,


22


are pushed into their respective decocking lever holes


16


molded into the left and right housing cavities


1


and are then inserted into these slots (FIG.


5


). These decocking levers


20


,


22


allow the user to rotate the decocker


21


downward and upward from the outside of the left and right housing cavity


1


. The decocker


21


is connected to the blocking bar


19


by means of a ball chain


23


inserted through small holes molded into each of them (FIG.


6


). This ball chain


23


is then looped over the ball chain post


10


molded into both the left and right side housings


1


shown in

FIGS. 8-10

. This will cause the ball chain


23


to lift the blocking bar


19


as the decocker


21


is rotated downward. As the blocking bar


19


is pulled upward, it will lose contact with the notch on the top of the snapper


18


, and the pressure from the main spring


24


will pull the snapper


18


forward and reset the training pistol in its original or double-action position. The user would then rotate one of the decocking levers


20


,


22


, and therefore the decocker


21


, back upward, releasing the upward pull on the ball chain


23


, and allowing the torsion spring


1


to rotate the blocking bar


19


downward finally resting on top of the flat portion of the snapper


18


. This would complete the transition back to the starting or double-action position.




Molded into the right side housing below and rearward of the ball chain post


10


, there is a small flat ledge known as the blocking bar stop


9


. This is to prevent the blocking bar


19


from causing too much downward pressure on the snapper


18


and preventing it from rising sufficiently to lose contact with the trigger


17


. If this occurs, the training pistol will not give the user the sensation that the pistol has been fired.




Once the interior components have been installed, the left side housing is placed symmetrically against the right side housing


1


. The left decocking lever


22


is inserted through the decocking lever hole


16


and into the rectangular slot in the decocker


21


.




The left side housing is then secured to the right side housing


1


by inserting screws or some type of fastener through the three mounting lugs molded into the left side housing and into the corresponding front, grip, and blocking bar mounting lugs


4


,


5


,


6


molded into the right side housing


1


.
