Frequently Asked Questions

Will this magazine work with all Taurus GX4 variants?

This ProMag drum magazine is specifically designed to fit the Taurus GX4 chambered in 9mm. It is not compatible with other Taurus models or different calibers. If you're unsure whether your specific GX4 variant is supported, we recommend confirming the model designation on your firearm before purchasing.

Is this magazine legal to purchase and use in California?

Yes — this magazine is California-compliant, blocked to a 10-round capacity as required by state law. While the drum body is designed to hold 50 rounds, it has been permanently restricted to 10 rounds to meet California's magazine capacity regulations. Always verify compliance with your local laws before purchase.

How reliable is the feeding on a drum-style magazine compared to a standard box magazine?

ProMag engineered this drum magazine with a heat-treated stainless steel spring and a precision injection-molded follower to ensure consistent round presentation and reliable feeding. While drum magazines can require a short break-in period, ProMag's quality control and lifetime guarantee reflect their confidence in long-term performance under normal range conditions.
