This is a ProMag® STEEL 7-round magazine for Beretta® 21 Bobcat™ pistols in .22 LR.
These heat-treated steel magazines come with a handy reloading button and a baseplate & follower made from ultra-durable DuPont Zytel polymer. From their iconic styling to the flip-up barrel, Beretta’s smaller handguns are easy to recognize & fun to shoot. And over the years, Mec-Gar has steadily evolved their magazine’s design to improve function and reliability. All ProMag magazines come with a lifetime replacement guarantee, so you’ll always have a working mag on hand—no matter what.
