Abstract

A weighted body adapted for insertion into an existing gun magazine shell approximates the weight and/or density of live ammunition cartridges. The size and shape of the body allows for insertion down and into the slot at the top on the magazine, pressing down on the spring, with a sliding retainer stop or other feature to maintain the weight in position, filling or partially filling the internal volume of the magazine with the weight. The integral slide retainer stop attached at the top of the device is then moved or slid by the operator into a position that locks the weight into the magazine so it cannot pop back out due to spring pressure and will not interfere with other workings of the gun slide or receiver. A plurality of color-coded stops may be provided for use with the same or different weighted bodies corresponding to different calibers of ammunition.

Dependent claims

An article for simulating the weight of ammunition adapted for insertion into an existing gun magazine having an outer shell with a top opening for inserting the ammunition against a follower and an internal spring disposed within the magazine shell, and wherein the existing gun magazine is adapted for insertion into the bottom of gun handle, the article comprising:

a weighted body with a top, a bottom a length, front and back surfaces and opposing side surfaces;
wherein the weighted body is dimensioned for insertion into the existing magazine shell through the top opening thereof, thereby compressing the follower against the spring within the existing magazine shell;
wherein the top of the weighted body includes a device to maintain the body within the existing magazine shell once inserted;
wherein the device used to maintain the body within the existing magazine shell is a retainer stop that moves from front to back on the top of the weighted body;
and
wherein the weighted body contains no ammunition but has a predetermined weight corresponding to the weight of the ammunition adapted for insertion into the same existing magazine shell.
