Frequently Asked Questions

Which Ruger P Series pistols is this magazine compatible with?

This ProMag drum magazine is designed to fit Ruger P Series 9mm pistols, including popular models such as the Ruger P85, P89, P93, and P95. Always verify compatibility with your specific model before purchasing, as minor variations between generations can affect fit and function.

Why does this magazine have a 50-round drum body but only a 10-round capacity?

California law restricts magazine capacity to 10 rounds for handguns. This magazine uses the full 50-round drum housing for its structure and aesthetics, but is blocked and configured at the factory to feed only 10 rounds, making it fully compliant for purchase and use in California.

How does the ProMag drum magazine perform compared to factory Ruger magazines?

ProMag engineers the upper tower with a full-length steel internal insert that mirrors the construction of factory magazines, providing reliable feeding and a secure fit. The stainless steel spring and precision-molded follower further support consistent performance. As with any aftermarket magazine, we recommend testing with your preferred ammunition at the range to confirm reliable function in your specific firearm.
