50 Schuss mit SCHMEISSER S50 MLE

With the S50 MLE magazine adapter, SCHMEISSER is presenting an innovative solution at SHOT Show 2026 for anyone looking for maximum magazine capacity without the disadvantages of classic drum magazines. The adapter expands an original GLOCK® 17 magazine (9 mm Luger) to 50 rounds, yet remains surprisingly compact and easy to handle.

Technical concept: Four rows instead of a drum

At the heart of the design is a patented 4-row stacking system that arranges the cartridges in four rows. This gives the S50 MLE a capacity of 50 rounds in a size that is more comparable to an extended straight magazine than a bulky drum. This reduces weight, simplifies handling, and ensures familiar magazine guidance.

Installation without a gunsmith

The adapter is mounted on an original GLOCK® 17 magazine with few tools and without permanent modification. A special disassembly tool is included. The installation is reversible—the magazine can be restored to its original condition at any time. It is important to observe the safety instructions, as all springs are under high tension.

Materials, inspection, and suitability for everyday use

Made of glass fiber-reinforced polymer, the S50 MLE is designed for high resilience and low weight. Side windows allow for quick visual inspection of the fill level. Magazine loaders are recommended for loading. In addition to the included SCHMEISSER loader, MagLula UpLULA® and MagPump™ are also compatible.

Compatibility and instructions for use

SCHMEISSER expressly recommends the use of original GLOCK® 17 magazines and high-quality 9 mm ammunition in brass casings to ensure reliable feeding. The adapter is designed for weapons that accept GLOCK® 17 magazines. Cleaning is recommended after approximately 1,000 rounds.

Conclusion: The SCHMEISSER S50 MLE is a technically sophisticated alternative to drum magazines: high capacity, slim design, and easy handling. Developed and manufactured in Germany, the system is aimed at sport shooters, authorities, and users who want to combine maximum fire readiness with a classic magazine layout.
