Description

FIELD OF THE DISCLOSURE

The present disclosure relates to a firearm magazine, and more particularly, a firearm magazine for storing and dispensing cartridges. The housing of the magazine comprises a transparent or translucent outermore shell molded over the entire outer face of the housing, enable to cover all of the cartridge indicators, including slots and/or holes.

BACKGROUND OF THE DISCLOSURE

Generally, firearms, such as pistol, are used with a magazine to feed cartridges to the weapon. The magazine generally comprises a housing to contain and guide the cartridges, wherein the housing comprises a plurality of bullet indicators, such as slots or through holes formed on the housing to allow the user to recognize how many bullets remaining within the housing. However, the dust, the dirt, or the pollutant may easily pass through the bullet indicators, such that the cartridges are easy to be jammed inside the housing.

In order to solve the above-mentioned problem, the housing of the magazine may be made of transparent or translucent material, such as transparent or translucent polymer without having any bullet indicators, including slots or through holes, forming on the housing, so as to facilitate the user observing how many bullets remaining. However, the transparent or translucent polymer material may also allow the enemy to observe the bullets remaining in the housing; moreover, the light reflection generated over the transparent or translucent polymer material may expose the user's shooting location. In such way, it may be dangerous for using the transparent or translucent housing in the battlefield.

In addition, one of the problems associated with the prior art is that polymeric materials exhibit creep at room temperature or human-survivable weather temperatures, where the magazine will usually be stored. Creep in polymeric firearm magazines is particularly exacerbated at the guiding lips of the magazines, because the guiding lips are under constant stress from the follower, spring assembly, and cartridges pressing against the guiding lips. The guiding lips experience a constant stress while the cartridges are loading and/or unloading therethrough. This constant stress causes the gap between the feed lips in a polymeric magazine to widen over time, resulting in a magazine that does not properly constrain the cartridges and/or feed reliably.

Therefore, there may exist a desire to develop a magazine for firearm having not also a strong, rigid, durable, high-safety operation structure, but also provide the user to recognize the amount of the cartridges remaining within the magazine.
