Description
This ProMag magazine is built to feed your Beretta 21A Bobcat reliably. The heat-treated steel body provides solid construction that'll handle regular use at the range or for backup carry. The follower and base plate are molded from a proprietary DuPont Zytel polymer, while the spring is formed from heat-treated music wire—the kind of robust design ProMag puts into their magazines.
The 7-round capacity matches what your Bobcat was designed to hold, keeping the gun balanced and concealable while giving you a solid amount of ammunition. A flat steel base plate helps with quick magazine changes and works well for deep concealment carry. If you pay attention to how you load it and run it through a few cycles before serious use, it'll function smoothly feeding those little .22 LR rounds.
Made in the USA, this is a straightforward spare or replacement magazine. ProMag backs these with a lifetime manufacturer warranty against defects, so you're covered.

Frequently Asked Questions
Will this ProMag magazine work with my Beretta 21A Bobcat?
Yes, this BER04 magazine is specifically designed as a direct-fit replacement for the Beretta 21A Bobcat in .22 LR. The 7-round capacity matches the factory specification for this model.
Is it normal for a new magazine to be stiff?
New magazines can come with stiff springs that make loading to full capacity difficult at first. Run the magazine in and out of your pistol a few times, load and unload it with snap caps or dummy rounds, and the spring will break in. A little light gun oil during this process helps smooth things along.
Can I use this as a spare magazine for the range?
Absolutely. This is a reliable spare or replacement magazine for training and recreational shooting. It's also compact enough to carry as a backup if you choose to do so.
What's included in the box?
You get the magazine itself. The detachable base plate is removable for easy cleaning and maintenance, which is useful when you want to keep things running smoothly.
What kind of ammunition works best in this magazine?
This magazine feeds standard .22 LR ammunition. The Bobcat platform runs best with high-velocity loads like CCI Mini Mags or Stingers, especially when you're new to the gun or haven't fully broken in your magazine yet.
Is ProMag a reliable brand?
ProMag is one of the leading handgun magazine manufacturers in the world. Their magazines use high-carbon heat-treated steel bodies and precision-wound springs. All ProMag magazines are backed by a 100-percent manufacturer's warranty against defects.
