What Makes This Glock OEM 13-Round Magazine the Right Choice?
When you’re running a G26, you’ve chosen a tool for its concealability and the legendary Glock reliability baked into a small frame. The trade-off is capacity. This factory 13-round magazine solves that problem without introducing a new one. It’s not an aftermarket part hoping to work; it’s the exact same magazine body and spring assembly Glock builds for their larger 9mm models, engineered from the start to lock into your G26. That means zero guesswork on feed reliability or holster fit. You get a known quantity that performs exactly as the factory intended.
Key Features of the Glock OEM G26 13-Round Magazine
- Factory OEM Construction: This is not a “compatible” magazine. It is manufactured by Glock to their specifications, using their tooling and quality control. The polymer, steel liner, and spring are all genuine Glock components.
- 13+1 Round Capacity: Effectively doubles your on-board ammunition compared to the standard 10-round G26 magazine, turning your subcompact into a much more capable primary or backup firearm.
- Drop-Free Guarantee: The magazine is machined and molded to the exact tolerances required for a positive, drop-free release from the G26 magazine well every time.
- Full Interchangeability: This magazine is compatible with all 9mm Glock double-stack pistols (G17, G19, G34, etc.). It also functions as a spare magazine for those larger frames.
- Proven Reliability: It utilizes the same feed lip geometry, follower design, and spring tension as every other OEM Glock 9mm magazine. There’s no break-in period and no reliability lottery.

The Glock OEM magazine sits in the sweet spot: proven reliability at a fair price.
Pros and Cons of the Glock OEM G26 13-Round Magazine
Pros:
- ✅ Guaranteed Reliability: It’s a Glock part in a Glock. The feed cycle is proven across decades of use.
- ✅ Perfect Holster Fit: Because it’s the factory-specified extended magazine, it won’t interfere with holsters designed for the G26 with a 13-round mag.
- ✅ No Break-In Required: Load it and run it. The spring is correctly tensioned from the factory.
- ✅ Increases Utility: Transforms your easily-concealed G26 into a more capable home defense or duty backup option.
- ✅ Maintains Resale Value: Factory magazines are always preferred and expected when selling a firearm.
Cons:
- ❌ Increases Print for Concealment: The extended baseplate will print more than the flush-fit 10-round magazine. For deep concealment, stick with the standard mag.
- ❌ No Fancy Baseplate: It’s a simple, functional polymer baseplate. If you want a weighted, aluminum, or custom-colored baseplate, you’ll need to purchase one separately.
Who Should Buy the Glock OEM 13-Round Magazine?
Buy it if: You own a Glock 26 and want a factory-original magazine for increased capacity. This is ideal for home defense configuration, as a duty backup magazine, for range training to reduce reload frequency, or if you simply want the assurance of OEM parts in your firearm. It’s also the best choice for new G26 owners looking to build out their magazine inventory with reliable components.
Skip it if: Your sole purpose for the G26 is ultra-deep concealment where the shorter magazine is non-negotiable. Also, if you are restricted to 10-round capacities by local law, this magazine is not for you. For those seeking maximum capacity in a smaller package, a Glock 19 magazine with a sleeve might be a better fit, though it will be longer.
Frequently Asked Questions
Is this a genuine Glock magazine?
Yes. This is a factory-original equipment manufacturer (OEM) magazine produced by Glock GmbH in Austria. It is not an aftermarket or “compatible” magazine.
Will this magazine fit my Glock 26 Gen 5?
Absolutely. This Glock OEM 13-round magazine is compatible with all generations of the Glock 26, from Gen 1 through the current Gen 5. The magazine well dimensions have remained consistent.
Does it come with a finger extension?
It comes with the standard Glock polymer extended baseplate, which provides a full grip for most hands. This is not the same as the optional “pinky extension” sold for the 10-round magazine; it is the standard baseplate for the 13 and 15-round Glock 9mm magazines.
Can I use this in a Glock 19 or Glock 17?
Yes. This magazine is fully interchangeable with all 9mm double-stack Glock pistols. It will function perfectly in a G19, G17, G34, etc. In a larger frame, it simply sits flush or slightly recessed in the magazine well.
How many rounds does it actually hold?
It is designed and rated for 13 rounds. As with any new magazine, the spring may be very stiff initially. Using a magazine loader is recommended for the first several loadings to ensure you can fully load it to capacity.

I don’t write reviews often but glockswitchstore.com deserves one. The Glock OEM 13-Round Magazine G26 9mm is exactly what I was looking for. Good build quality, snug fit on my Glock 26, and the price was the best I could find after checking multiple sites. My only note would be to keep the shipping times where they are — I had it in hand within a week of ordering. Will be a repeat customer.

Bought this as part of a larger build project. glockswitchstore.com had the best price by a decent margin and shipping was fast. The Glock OEM 13-Round Magazine G26 9mm itself is well-made — No wobble at all. Overall this is exactly what I needed. Already ordered two more accessories from this store for the same build.
