This is the 30-round drum magazine for the Smith & Wesson M&P Shield Plus, manufactured by Promag.

The high-grade steel and polymer used in this Shield Plus drum magazine allow it to endure many detrimental environmental factors, such as extreme heat and moisture.

Rather than use a steel body, Promag’s DuPont Zytel-based polymer shaves off a good amount of weight, allowing this magazine to be a lighter alternative to others of its kind.
