A lot of folks are under the impression that GLOCK magazines are plastic. And even those who know there’s a stainless steel body hiding inside the plastic overmold haven’t actually seen what it looks like. So…wonder no more.

  1. I still prefer the early, non fully lined versions.
    With ~10 rounds or more the mag would drop slightly but remain in the gun, with less than 10 rounds they would drop completely out.

  2. hmmmm all these years I thought that the lips were just painted silver.

    next thing your going to tell me is they wont pass through a metal detector undetected.

    • Nope, only a Glock 7 will make it through a metal detector without a hiccup.

  3. The original ones were meant to be polymer with steel lined feed lips. They wouldn’t drop free, so they made them full metal lined. Unfortunately, that means that Glock is stuck with a fat mag while all other handguns have thinner mags. Modern aftermarket mags have full polymer bodies and can still drop free.

    • “Unfortunately, that means that Glock is stuck with a fat mag while all other handguns have thinner mags.”

      I concur. I don’t see the benefit to it. It makes them thicker and stickier in the frame. I’ve seen a ton of comments on here and elsewhere about other guns, like the CZ P-10 C for instance, saying something like, “it would be better if it used GLOCK mags.” Well, sure, GLOCK mags are reliable but a reliable, non-plastic-wrapped mag that’s thinner, lighter, and inserts and drops more easily is even better!

      • While I don’t like how fat Glock mags are and how difficult it is to get the floor plate out, it’s hard to deny its market share. I wouldn’t buy a 5.56 semi auto that didn’t take AR mags, so all of my 9mm pistols only take Glock mags. That means they’re only Glocks. There are numerous aftermarket mags that are good, and OEM mags are cheap and plentiful. I only wish the market standardized on Beretta 92, CZ-75, or Hi Power mags.

      • This.

        Glock mags aren’t the best, but because of popularity it has become the de facto standard. And so everyone is demanding new guns be compatible with glock mags.

        Maybe the trend would change if the runners up would agree on another standard, like all non iPhones agreed on micro usb.

        I’m thinking a good candidate would be sig p320 mags since they were recently adopted by the army.

      • I’d rather have CZ P-10 C type, or for that matter, most other types of mags. The base plate work on a GLOCK mag is not amusing.

        • It may be thin, but the grip is still quite angular compared to the other polymer options that use a steel mag.

  4. Now I have a tear falling down my cheek as a perfectly good G20 mag is headed for the land fill…

    • Nah, they saw the need to fully steel line a polymer mag that flexed enough when fully loaded that it wouldn’t drop free.

      • Yup. Basically early Glock’s were not actually “perfect” but instead of refining the magazine design to accommodate the thinner metal one , Glock decided to jury rig the existing design

  5. Jeremy, are you going to get a 9×25 Dillon barrel for that G20 and run some Underwood ammo through it and a ballistic vest or two? 😉 Alternatively, Uwood just came out with a 100 grain xtreme defender load for 10mm at 1800 fps!

    • Actually, I did that two weeks ago. Gotta edit up all the video but I shot a bunch of rounds at a IIIA vest, a IIIA Kevlar plate thing, and a III+ steel body armor plate. 9×25 Dillon included!

  6. I love glock mags- no rust on the mag bodies from IWB carry. Same reason I love the plastic mag release. Had both of these items rust on M&P Shield.

  7. what happens when you open up a glock mag?

    nothing special. the exact same feeling i get when i handle one.

  8. I love Glock mags. For one thing, they always work. I have some old 10 round G21 mags from the Clinton era that have been used for USPSA matches, loaded and emptied hundreds of times, dropped in the dirt, and never fail. And unlike XD mags with the sharp feed lips, they don’t hurt your fingers to load six or eight times each at the range, and they don’t chew up the elastic retainers in my soft pistol cases.

    In short, they work every time with no drama, just like Glock pistols.

  9. Glock Schlock. My Steyr magazines are still made of steel.

    Sadly they don’t have the second cutout so it will lock up if you flip the mag release over for a lefty but they promised me they’ll start shipping those when they run out of the originals. /s

  10. Why doesn’t Glock make flush magazines like the ones on 1911’s? That base plate looks like a tumor or a growth on the bottom of the gun! I’m trying to figure out a way to weld a metal piece to the bottom of the Stainless part of the magazine. So when it’s inserted it will be flush with the frame. Let me know if anyone an idea of how to do it Thanks Jay
