The Glock® ‘Big Stick’: Legendary 33-Round OEM Reliability

In the world of high-capacity magazines, there is one that stands above the rest. The Glock Factory 33-Round 9mm Magazine, affectionately known as the “Big Stick,” is the gold standard for extended firepower. Originally designed for the select-fire Glock 18, it has become the most popular accessory for 9mm Glock owners and Pistol Caliber Carbine (PCC) shooters worldwide.

Whether you are running a Glock 19 Gen6, a Kriss Vector, or an AR-9, the “Big Stick” provides the unrivaled reliability that only a factory Glock magazine can deliver.

Why the ‘Big Stick’ is the Industry Standard

Unlike aftermarket high-capacity mags, the Glock OEM 33-rounder is built with the same duty-grade materials as their standard carry mags:

• Steel-Reinforced Construction: A hardened steel insert is encased in Glock’s proprietary high-tech polymer. This prevents the feed lips from spreading, even when kept fully loaded for years.

• The +2 Extension: The magazine officially holds 31 rounds in the body, with a factory-installed +2 basepad extension, bringing the total to a massive 33-round capacity.

• Gen5/Gen6 Upgrades: Modern versions feature the High-Visibility Orange Follower, allowing for instant visual confirmation of an empty chamber.

• Universal Compatibility: This magazine fits every double-stack 9mm Glock ever made, including the G17, G19, G19X, G26, G34, G45, and the new G47.

The 24-Round “Little Brother”

For those who want extended capacity in a more compact profile, Glock also offers the 24-Round Factory Magazine.

• The “Goldilocks” Size: It offers significantly more rounds than a standard mag but is easier to carry in a gear bag or vehicle console than the full 33-round stick.

• Competition Ready: At roughly 165mm, it is a favorite for competitive shooters who need a “stage mag” that provides extra insurance without the bulk of a full stick.

Perfect for Your PCC (Pistol Caliber Carbine)

If you own a carbine that accepts Glock magazines—such as the Ruger PC Carbine, Kel-Tec SUB-2000, or a 9mm AR-15—the “Big Stick” is a mandatory accessory. These firearms are designed to run through ammunition quickly, and the 33-round capacity allows you to spend more time shooting and less time reloading.

Buy Factory, Forget the Rest

While translucent and budget-priced aftermarket magazines are tempting for the range, the Glock Factory ‘Big Stick’ is the only one trusted for defensive use. When the stakes are high, stick with the magazine that was built by the same engineers who built your pistol.
