    Good, quality magazine

    This is now my favorite, go to magazine for my Px4. Almost the same exact footprint as the Beretta 20 rounders, but seems to be of a higher quality. Which is kind of weird, all things considered. 100% recommend this magazine over the Beretta 20's, which I also own a few of. Nicer quality, holds an additional round and has the 21 round shot count on the back. The bright green follower basically advertises carbon, but I guess that's a good thing? Helps you make sure to keep your magazine clean.
