If you run a .40 S&W Glock 22 or 23, you've probably noticed that drum magazines for your caliber are thin on the ground—the market has been flooded with 9mm options while .40 shooters got left behind. The ProMag 50-round drum magazine for Glock 22/23 changes that equation. This is a serious high-capacity option purpose-built for your platform, holding 50 rounds of .40 S&W in a single magazine.
ProMag engineered this drum to handle real use. The body is injection-molded from Zytel polymer, a material chosen for strength and longevity through extended range sessions. Where durability matters most—the upper tower—ProMag reinforced the design with a full-length steel insert that's stamped and welded, matching the construction philosophy you'll find in factory Glock magazines. The internals are equally thoughtful: a heat-treated stainless steel magazine spring and an injection-molded follower round out the design. It's all finished in matte black and made in the USA.
Whether you're building a tack-driver for the bench, running drills at the range, or setting up a defensive carbine or pistol platform, a 50-round magazine eliminates frequent reloads and gives you serious trigger time between breaks. The 22/23 is a hard-hitting, accurate platform, and this drum brings the round count to match your ambition.
| Caliber | .40 S&W |
| Capacity | 50 rounds |
| Fits | Glock 22, Glock 23 |
| Material | Zytel polymer with steel insert |
| Spring | Heat-treated stainless steel |
| Finish | Black |

Yes. This ProMag drum is designed specifically for the Glock 22 (.40 S&W full-size) and Glock 23 (.40 S&W compact).
The magazine holds 50 rounds of .40 S&W ammunition.
No. This is a ProMag-manufactured aftermarket magazine. However, ProMag reinforced the upper tower with a full-length steel insert similar to OEM Glock magazine construction, and uses a heat-treated stainless steel spring and injection-molded follower for reliability.
This is a high-capacity range and training magazine. Use and legality depend on your local jurisdiction and intended purpose; check your state and local laws before purchase. For defensive applications, most shooters prefer smaller, faster-reloading magazines.
