Core construction and components

Made by Promag and offered in various model options, this 7 round replacement magazine is specifically compatible with the Beretta 21A Bobcat. The body is heat treated steel for corrosion resistance and dimensional stability under repeated use. The follower is an injected molded component designed to maintain consistent cartridge alignment, while the mag spring is formed from music wire to provide predictable spring rate and long service life. It’s assembled in the USA, which matters to shooters who prefer domestic manufacturing standards.

Why these features matter

Heat treated steel bodies resist wear from loading and holstering, reducing the chance of deformation that can cause feeding issues. An injected molded follower offers low-friction movement and better tolerance control than improvised followers, which helps reduce jams. Music wire springs keep tension over thousands of cycles—important for defensive magazines that may sit in a pistol for extended periods but must function perfectly when needed.

Fit, function, and value

Fit is straightforward: designed as a direct replacement or spare for the Beretta 21A Bobcat platform. At a price of $18.89, this magazine provides a cost-effective way to increase reload speed and redundancy without sacrificing reliability. Whether you keep one as a spare in a range bag or rotate several for carry, the Promag construction gives confidence in repeated operation.
