Drum Mag 50rd 9mm G19/G17

G19/17 50rd Drum Mag Overview

The 50rd Drum Mag holds 50 rounds of 9mm in a compact drum configuration that fits all double-stack Glock pistols. Load it up, lock it in, and you have serious capacity for range days, competition stages, or home defense setups. The drum feeds reliably and drops free when empty.

The body is glass-filled polymer with hardened steel reinforcement where it matters. Inside, a heat-treated chrome silicon wire spring handles the tension needed to push 50 rounds through the feed system. A ratcheting load assist lever makes loading manageable since stuffing 50 rounds by hand would get tedious fast.

Why Choose a 50-Round Drum

Maximum Capacity, Minimum Reloads
Fifty rounds is nearly three times what a standard G17 magazine holds. For range sessions where you want to shoot more and reload less, or competition stages where round count matters, the drum keeps you in the fight longer.

Works Beyond Pistols
This drum fits any platform that accepts Glock double-stack 9mm magazines. That includes pistol caliber carbines like the Kel-Tec Sub 2000, AR9 builds, and other Glock-mag compatible PCCs. The extra capacity makes even more sense in a carbine where you’re shooting faster and want fewer mag changes.

Load Assist Lever
The ratcheting load assist lets you wind in rounds without destroying your thumbs. Essential when you’re loading 50 rounds at a time. The mechanism is built into the drum body for easy access.

Steel-Reinforced Construction
The polymer body is glass-filled for impact resistance, with steel inserts at critical stress points. The combination keeps weight manageable while maintaining durability where the magazine takes the most abuse.

Compatibility

This drum magazine fits all double-stack 9mm Glocks from Gen 1 through Gen 5. That includes the Glock 17, 17L, 18, 19, 19X, 26, 34, 45, and 47. It also works in 3D printed frames built for double-stack Glock magazines, such as the DD17.2, DD19.2, and DD26.2.

The drum is also compatible with most pistol caliber carbines that accept Glock magazines. Function in PCCs is generally reliable, though the manufacturer notes that fit and function in carbines is not guaranteed since there are many different PCC designs on the market.

Not compatible with single-stack Glocks like the G43, G43X, or G48.
