Description
This Mec-Gar magazine fits the Beretta 21 Bobcat and holds 7 rounds of .22 LR ammunition. The blued carbon steel tube is heat-treated for strength while maintaining the dimensions needed for smooth feeding into your pistol. You'll get a high-impact polymer follower that keeps rounds aligned and a high-tensile music wire spring that's built to last through regular use.
Mec-Gar's Italian Engineering for the Bobcat 21
Mec-Gar has been manufacturing firearm magazines since 1965 and supplies factory magazines to major firearms companies, including Beretta. That means this magazine uses the same construction methods and materials as the factory Beretta version, just without the markup. The steel construction with a removable metal butt plate gives you a flush-fit design that won't snag during draws, while the built-in loading tab makes it easier to seat rounds without finger fatigue.
Tested Reliability in the Field
Owners of the 21 Bobcat have reported that upgrading to a fresh Mec-Gar magazine can eliminate feeding problems that plagued older or worn factory mags. The dimensional tolerances are tight enough to ensure rounds feed smoothly without getting hung up, which matters with .22 LR since rimfire ammo can be finicky. If your Bobcat has been giving you trouble with jams or failures to feed, swapping in this magazine often resolves the issue entirely.
Good for Range Work and Casual Shooting
Whether you're running through a box of .22s at the range or keeping a spare mag in your pocket for plinking, this magazine will serve you well. The 7-round capacity keeps the Bobcat compact while giving you a full reload's worth of ammunition. The blued finish resists corrosion, so your mag will keep working whether you're shooting indoors or in outdoor conditions.

Frequently Asked Questions
Will this magazine work with both Beretta 21 and 21A Bobcat models?
Yes, this magazine is compatible with both Beretta 21 and 21A Bobcat pistols. All current production magazines work with both pre-2013 and 2017+ Bobcat production runs, so regardless of when your pistol was made, this Mec-Gar magazine will fit and function properly.
What makes Mec-Gar magazines better than aftermarket alternatives?
Mec-Gar manufactures the OEM factory magazines for Beretta, so this magazine is functionally identical to the factory version. The difference is in the build quality and fit. Users consistently report that Mec-Gar magazines eliminate feeding problems that cheaper aftermarket brands struggle with, especially with rimfire ammunition.
Can I use this magazine for .25 ACP instead of .22 LR?
No, this magazine is caliber-specific and designed only for .22 LR ammunition. Mec-Gar makes separate 9-round magazines for the Bobcat in .25 ACP, which have different internal dimensions to safely feed that larger cartridge.
Is the floorplate removable for cleaning?
Yes, the metal floorplate is removable, allowing you to easily disassemble the magazine for cleaning and maintenance. This makes it simple to keep the magazine in good working order or to replace internal springs and followers if needed down the road.
