    Are 22-round .40S&W Magazines original factory equipment?

    Several years ago, I came across what appeared to be Glock-manufactured .40 S&W magazines which held 22 cartridges. Not being one to thumb my nose at higher-capacity options (especially when they appeared to be original factory equipment (complete with Glock’s imprimatur), I naturally purchased a pair.

    These 22-round magazines were a trifle longer than the 17-round (15+2) magazines that I already owned, and they protruded over 2 inches beyond the base of my Glock 23’s grip. Since they were meant to be carried as reloads, however, I didn’t mind their extra length one bit.

    What really disappointed me was that both of these new 22-round magazines failed to work properly with my Glock 23.

    Every time I loaded them to full capacity and took them to the range with me, they would fail to cough up their full complement of cartridges. At some point during the firing string, the .40 S&W cartridges would always nose-dive inside those magazines, resulting in a failure to feed in every instance. It didn’t matter what sort of .40 S&W ammunition I used, either. The malfunction manifested itself with full metal jackets and with every brand of hollow points I tried.

    I have no idea whether this is a common occurrence with these 22-round magazines, or if I simply obtained a bad pair. I have not had the chance to test these extended magazines with a full-size Glock 22, to determine whether they work properly with the larger gun. At this point I'm even starting to question if Glock actually manufactured them at all, or if they were the work of some clever shyster.

    Suffice it to say that they have never worked properly with my Model 23, and I would never dream of carrying extra ammunition in these magazines, as reloads for defensive carry. I happen to believe that every piece of carry equipment needs to deliver 100% performance every time, and magazines are no exception.

    These two magazines have since been locked away, until I find the time to take them apart and hopefully, find out why they behave so badly.

    Can anyone tell me if Glock actually released these 22-round .40S&W magazines?

    Yes, Glock does make these magazines. Can you verify if your magazines have the Glock logo ? link to OEM mag for sale/clik here

    Yes. They have the Glock logo, which is why I purchased them.

    Looks like I got a pair of lemons, then!

    Glock is rather uptight about magazines, give them a call - the number is at the bottom of their website. Good chance they will repair or replace if you send in.
