Important Notice

Frequently Asked Questions (FAQ)

How can I prevent gas leaks?

Regularly lubricate the seals with silicone oil and avoid storing the magazine completely empty. It is best to keep a small amount of gas inside during storage.

Can I use stronger gas for higher performance?

While Red Gas can theoretically be used in cold weather due to lower gas expansion, it is not recommended. Stronger gases increase wear and may damage both the magazine seals and internal pistol components.

Will it fit other Glock and G-Series pistols?

The magazine is primarily compatible with UMAREX / VFC (Elite Force) pistols. Compatibility with other manufacturers (WE, Tokyo Marui, VORSK) cannot be guaranteed and may result in feeding or fitment issues.
