    Good mag for my Bobcat

    Been running this mag in my Beretta 21A for about a month now and its been pretty reliable at the range. I put maybe 200 rounds through it so far with only a couple of hiccups on the last round not feeding right but thats pretty normal for 22lr honestly. The fit is nice and snug in the gun, no wobble at all which is what I was worried about with an aftermarket mag. Would buy another one to keep as a spare.

    Fits the Beretta 21A perfectly with no wobble
    Good price compared to factory mags

    Fits My Bobcat Like a Glove

    Been carrying my Beretta 21A for a while now and the original mag was starting to show some wear so I grabbed this Mec-Gar to replace it and honestly I couldnt be happier, drops in smooth and locks up solid every single time. Loaded it up with 7 rounds of Federal high velocity and ran through it at the range without a single hiccup which is more than I can say for some of the cheap aftermarket stuff I tried before. The flush fit floorplate sits perfectly against the grip, doesnt stick out or snag on anything which is HUGE for a carry gun this small. Only tiny gripe is the blued finish can show fingerprints pretty quick but thats really just me being picky, a quick wipe with an oily cloth and youre good.

    Feeds reliably with quality 22LR ammo
    Flush floorplate sits perfectly flush with the grip

    Blued finish shows fingerprints and oils easily
    Only 7 rounds but thats just the gun design not the mag

    I purchased this to replace the original magazine in my Beretta 21A, which had become rather worn after many years of use. The fit was proper and it fed rounds cleanly through a couple of range sessions, though the floorplate sat just slightly proud of the grip on my particular pistol. Overall I am quite satisfied with it, and my retriever seems to appreciate that I am spending more time at the bench than walking him on range days.

    Factory-correct fit and feeding

    I ordered the Mec-Gar Beretta 21 Magazine and was impressed by how quickly it arrived. The magazine fits perfectly and works just as well as the factory mags. The site kept me updated on the order status, which was very helpful.

    Highly recommend!

    These magazines are spot-on replicas of the OEM mags that came with my gun every detail matches, from fit to function! They fed flawlessly with modern .22 LR, though I did hit a snag with some 60-year-old heirloom ammo from my grandfather (no surprise there). Once I switched to fresher rounds, everything ran like clockwork.

    Matches factory mags in fit, feed, and reliability with modern ammunition.
