Abstract: A magazine for firearms is provided with either a double or single row of cartridges. The magazine is particularly for use with automatic or semi-automatic pistols. The magazine includes a magazine housing for ammunition having a magazine housing bottom. A follower and spring are provided within the magazine housing for moving the cartridges upward away from the bottom. The follower is provided with a curved upper edge with a radius larger than the radius of the cartridges or ammunition. This curved upper edge connects with a curved top tapered edge of the follower to form an inclined upper side. The base of the follower has an inclined surface and a cavity for receiving coils of the spring. A wall of the cavity and the inclined side meet at an edge of the inclined surface at a beveled region. The magazine spring has an upper taper part that fits snugly into the cavity or notch of the follower when the magazine is fully loaded with ammunition.

Abstract: This invention refers to a magazine for firearms, including a chamber (11) with two lips (14) that are elasticized by at least one slit (15) in each side wall of the chamber to enable the insertion of each round of ammunition through a temporary divarication of the lips, obtained by resting the ammunition on them and exercising a pressure in the same direction to counteract the thrust of the spring on the elevating mechanism.
