Description

CROSS-REFERENCE TO RELATED APPLICATION(S)

This application is related to and claims priority from U.S. provisional application No. 62/118,680 filed on Feb. 20, 2015 entitled “Loaded Magazine Simulator”. The 62/118,680 application is hereby incorporated by reference in its entirety

FIELD OF THE INVENTION

The present invention relates to firearm training systems and methods and, more particularly, to devices for simulating a loaded magazine for a firearm.

BACKGROUND OF THE INVENTION

A magazine is a device for storing ammunition for a firearm and for feeding ammunition to a fully automatic or semi-automatic firearm. The magazine can be detachable from the firearm or integral to the firearm. The magazine can move ammunition rounds stored in the magazine into a position where they can be loaded into a chamber by the action of the firearm.
Firearm training requires a safe and efficient way to practice dry fire, malfunction clearing and emergency reloads. For dry fire drills with the magazine in place, an operator needs to rack the slide to reset the action without the slide or the bolt locking back. For malfunction clearing drills with the magazine in place, the operator needs to a) rack the slide to reset the action, and b) simulate loading a round into the chamber, without the slide or the bolt locking back.
One approach to the drills described above is to use one or more dummy rounds. A dummy round is a device that can be loaded in a conventional fully automatic or semi-automatic weapon, and configured in the same way as a standard round of live ammunition. The dummy is typically loaded, chambered and ejected from the firearm in the standard way.
A disadvantage of using dummy rounds is that the rounds must be loaded before dry firing and the ejected rounds must be retrieved after dry firing. In addition, there is a possibility that an operator can load and fire a live round by mistake. It is desirable that the operator can practice the drills without using dummy rounds and with no possibility of inadvertently loading a live round.
Another approach to the drills described above is to replace a loaded magazine in a gun having a magazine chamber with an inert magazine, the inert magazine resembling the loaded magazine in its size, shape and weight.
Yet another approach to the drills described above is to use a device that can be loaded in a magazine that allows the slide to operate without being locked back by the follower. When loaded, the device can position the follower such that the follower is unable to engage the slide stop. The device can have a low profile which allows the slide to pass over it without the device being ejected from the magazine.
One disadvantage of existing devices is that they can rotate in the magazine, thereby obstructing the slide.
Another disadvantage is that only one device can be loaded into the magazine at a time. It is desirable that a firearm training device simulate the weight of a loaded magazine.

SUMMARY OF THE INVENTION

A loaded magazine simulator includes: a channel wherein the channel is defined by a first top edge and a second top edge; a bottom feature; a lip; and at least one lower edge. The channel is configured to allow a slide of a firearm to move without causing the loaded magazine simulator, which is configured to be loaded into a magazine, to be ejected from the firearm.
In some embodiments, the lower edge is configured to prevent the loaded magazine simulator from rotating and/or to orient the loaded magazine simulator in the magazine.
In some embodiments the loaded magazine simulator is configured to stack with a second loaded magazine simulator in a magazine.
In some embodiments the weight, length, and/or height of the loaded magazine simulator is substantially equivalent to that of the live round the loaded magazine simulator is configured to replace.
In some embodiments the lip is configured to aid in removing the loaded magazine simulator from the magazine.
The loaded magazine simulator can be made of a variety of materials including zinc.

Construction of the Loaded Magazine Simulator

The loaded magazine simulators 100, 200, and/or 300 can be made of various sufficiently durable materials. The material can be selected to be hard enough not to fail under use, yet softer than the material used to construct the magazine and the firearm. When made from material selected accordingly to the latter criterion, the loaded magazine simulator will be less likely to cause damage to the magazine or the firearm. Ideally, the material should be selected such that the loaded magazine simulator is sufficiently heavy to simulate the weight of a live round.
One suitable material for the loaded magazine simulator is a soft, non-ferrous metal. In one embodiment, the loaded magazine simulator is made of zinc.
Other suitable materials can include:

- Plastic (including suitable acrylic, hard rubber or epoxy)
- Tin or tin alloy (such as pewter)
- Zinc or zinc alloy
- Copper or copper alloy
- Lead or lead alloy

In another embodiment, the loaded magazine simulator can include a plastic shell with a heavy core or ballast. The heavy core can include a sufficiently heavy material (such as the materials listed above). In some embodiments, ballast material can be added or removed, or otherwise changed, for example to simulate the weight of a live round.
In one embodiment, the loaded magazine simulator can be manufactured by casting, that is, by pouring molten metal or a liquid resin into a mold. In other embodiments, the loaded magazine simulator can be manufactured by machining, forging, printing or any other suitable manufacturing process.
Operation of a Firearm with the Loaded Magazine Simulator
In certain embodiments, for dry practice (dry fire), a chamber plug, such as the one described below, or another object that substantially obstructs the chamber so that a live round cannot be chambered and is intended to remain in the chamber while the slide or bolt moves through its normal range, can be inserted into the barrel from the ejection port or chamber end.
For dry practice (dry fire), a magazine containing one or more loaded magazine simulators can be loaded into the firearm. The operator can fully rack the slide to reset the action (trigger) without the slide or bolt locking back or the loaded magazine simulator being ejected from the firearm.
For practicing type 1 and type 2 malfunction clearing, a magazine containing one or more loaded magazine simulators can be loaded into the firearm. The operator can fully rack the slide to reset the action (trigger) and can simulate loading a round into the chamber without the slide or bolt locking back or the loaded magazine simulator from being ejected from the firearm.
For practicing type 3 malfunction clearing, the operator can insert a magazine containing one or more loaded magazine simulators into the firearm, and then fully rack the slide to simulate loading a round into the chamber without the slide or bolt locking back or the loaded magazine simulator being ejected from the firearm.
For practicing emergency reloads, the operator can a) release the slide and b) to simulate loading a round into the chamber.

Preparing a Firearm for Practice Using the Loaded Magazine Simulator

FIG. 5 is a flow chart illustrating method 500 for preparing an unloaded firearm for firearm practice by loading one or more loaded magazine simulators, such as the loaded magazine simulator of FIG. 1A.
At 510, a loaded magazine simulator (such as the loaded magazine simulator of FIG. 1A) is loaded into a magazine. In certain embodiments a chamber plug is inserted into the barrel of the firearm.
At 520, an operator of the firearm decides whether to load another loaded magazine simulator into the magazine. If yes, then method 500 proceeds to 510. If no, then method 500 proceeds to 530.
At 530, the operator loads the magazine comprising one or more loaded magazine simulators into the unloaded firearm.
At 540, the operator begins firearm practice with the loaded firearm comprising the magazine and one or more magazine simulators.

Benefits of the Loaded Magazine Simulator

The loaded magazine simulator can be loaded into a magazine in the same way as a live round. One or more loaded magazine simulators can be loaded into an empty magazine. The number of loaded magazine simulators loaded into an empty magazine can be selected to simulate the weight of a magazine containing live rounds.
A firearm empty of live rounds and loaded with a magazine containing one or more loaded magazine simulators can behave in a similar manner as a firearm loaded with a magazine containing live rounds, with the following exceptions: a) the firearm will not fire, b) the loaded magazine simulator will not be loaded into the chamber, and c) the loaded magazine simulator will not be ejected when the slide or bolt is manipulated.
As described with reference to FIGS. 1 through 3, the loaded magazine simulator can be configured not to rotate sufficiently in the magazine to cause the loaded magazine simulator to come out the top of the magazine. The loaded magazine simulator can be configured to be loaded or unloaded in the same way as a live round. The loaded magazine simulator can be configured to remain in the firearm during a practice session, and not be ejected during operation of the firearm as described above.
The apparatus and methods described above can be applied in a variety of situations related to firearms training and practice including, but not limited to, the following:

- Firearms instruction and training
- Dry fire practice
- Malfunction practice
- Reloading practice

While particular elements, embodiments and applications of the present invention have been shown and described, it will be understood, that the invention is not limited thereto since modifications can be made by those skilled in the art without departing from the scope of the present disclosure, particularly in light of the foregoing teachings.
