  • This invention relates to firearms. More particularly this invention relates to training ammunition magazines for semi-automatic pistols that permit dry fire training with the semi-automatic pistol. Even more particularly, this invention relates to training ammunition magazines that are of the single stack variety. BACKGROUND OF THE INVENTION AND DESCRIPTION OF RELATED ART
  • Live firing is the best way to practice drawing and firing a pistol. Practice process builds muscle memory, and helps the shooter develop proper techniques of delivery and complete weapon control. There are a variety of drawbacks to live fire training practice. Using ammunition is an ongoing expense, and measures have to be taken to practice with safety. This may include, without limitation, traveling to/from a firing range; providing/purchasing/maintaining safety equipment for the shooter and possibly others; and allotting special time in the schedule for the practice session.
  • Dry fire practice is a possible substitute for live fire practice, but is more widely recognized and accepted as an addition to, and supplement to, live fire practice. Dry firing is a practice technique that also builds muscle memory and a technique whereby a pistol, is drawn, aimed, and fired but without using live ammunition. This enables the practice of firing a pistol to proceed smoothly and accurately without all of the negatives of live fire practice. Because no live ammunition is used, there is no ongoing expense, there is no need to use safety equipment, a special shooting environment is not necessary, and practicing can be accomplished in much less time and in locations (such as a home environment) where it is more likely a firearm may be used in an unexpected emergency situation, such as a home invasion, burglary, robbery and the like.
  • Dry firing also allows the shooter to practice in the actual environment where the pistol may need to be used for protection such as in the home. With complete safety, actual shooting scenarios can be practiced in and around the home.
  • Practicing at the range can also be improved.
  • live fire is practiced at the range, the novice shooter usually has to spend a significant amount of time and expend a lot of ammunition getting accustomed to the report and recoil of the pistol.
  • some dry fire practicing can be done. The novice shooter can become accustomed to the trigger feel before having to deal with the recoil and the report of live firing.
  • a major negative factor occurs with most methods of dry firing because when a semi-automatic pistol is live fired, the “firing” resets the pistol’s firing pin and the pistol is ready to be fired again (repeatedly) until the magazine is empty. The shooter's hands remain in the firing position, and just the trigger finger and the trigger are employed.
  • the shooter With known dry fire practice, after the first activation of the trigger releasing the firing pin, the shooter must remove a hand from the pistol and ratchet the slide back in order to reset the firing pin. The pistol is then ready for another trigger activation. This must be done each time, and every time, a shot is simulated. Doing this, teaches improper muscle memory because it is not even remotely close to what happens during actual live fire. When people are in real shooting situations, they need to be able to depend on simply acting upon how they have practiced. Anything else could be deadly.
  • Some known dry fire training systems incorporate computer graphics into the training scenario.
  • Other known systems attempt to replicate the pistol’s recoil.
  • Still other use laser marking of "shots”, and still others project images onto a screen, etc.
  • Negative aspects of these known devices/systems include, but are not limited to, they are training intensive; they are expensive; they do not allow a user to practice with their own pistol; they have extensive “learning curves”; they all allow the firing pin of the pistol to be damaged by the repetitive un-cushioned release responsive to pulling the trigger, may require practice in a specific location (such as in front of a computer monitor) and none of the devices reset the firing pin after each successive trigger pull to allow simulation of the next shot.
  • Double stack pistols are wide enough (side-to-side dimensions of the pistol hand grip) for the ammunition to position itself in an alternating staggered array inside the ammunition magazine. This staggered positioning allows for more bullets to be in the magazine, but, also, necessitates that the pistol hand grip be wide enough to accommodate this wider magazine. This results in a thicker, more bulky and heavier pistol.
  • the present invention is a dry fire training device for use with a semi-automatic pistol having a magazine compartment defined in the semi-automatic pistol’s hand grip.
  • the magazine compartment is sized and configured to carry a single stack ammunition magazine which has a smaller side-to-side dimension because ammunition cartridges are arranged, and positionally retained in vertical stacked alignment, with one ammunition cartridge stacked substantially exactly on top of the ammunition cartridge immediately adjacent below, without any lateral offset.
  • single stack magazines may be criticized for an inability to accommodate (contain) a greater quantity of ammunition cartridges
  • single stack magazines have the benefit of being smaller and more compact, which allows the semi-automatic pistol, which is configured to utilize single stack magazines, to be smaller, more compact, lighter in weight, easier to handle/manipulate, and more easily concealed.
  • semi-automatic pistols may be favored by users who are smaller in stature, or those who need to limit the amount of weight they carry, such as members of the armed forces and undercover law enforcement officers.
  • Semi-automatic pistols have a trigger mechanism.
  • the trigger mechanism When the trigger mechanism is actuated by pulling the pistol's trigger, the pistol’s firing pin is released from a “cocked position” spacedly rearwardly of an ammunition cartridge, and the firing pin responsively moves rapidly forwardly to forcefully impact the ammunition cartridge, causing the ammunition cartridge to “fire”.
  • the release of the firing pin generates both an audible sound and a tactile “sensation” that are substantially simultaneous and which are difficult to accurately replicate.
  • the solution is to place the detente reed in an enlargement below the pistol's magazine well and make the enlargement wide enough and long enough to accommodate the detente reed.
  • the enlargement is oriented horizontally to look like a normal magazine extension which is used for a rest for the pinky finger.
  • the present invention resolves this unmet and continuing need,

Abstract

Le tir réel d'un pistolet semi-automatique, remet en place le percuteur, et le pistolet semi-automatique est prêt à tirer à nouveau. Avec la pratique du tir à sec, le tireur retire une main du pistolet et des rochets, la glissière remettant en place le percuteur pour simuler chaque tir. La présente invention concerne un chargeur de munitions simulé qui fournit un entraînement musculaire réaliste en dupliquant l'action de la gâchette d'un tir réel normal, la sensation et le son de la libération du percuteur, et la remise en place de la gâchette pour des activations de gâchette supplémentaires. Il n'y a aucune interaction avec le percuteur, et aucune modification du pistolet n'est nécessaire. Ce dispositif d'entraînement au tir à sec est suffisamment étroit pour être utilisé dans des pistolets à douille simple.
