Frequently Asked Questions

Is this magazine permanently blocked to 10 rounds, and is it legal in California?

Yes. This ProMag magazine is factory-blocked to a maximum of 10 rounds, making it fully compliant with California's magazine capacity restrictions. The block is a permanent modification to the 17-round body, so it cannot be readily converted to accept more than 10 rounds. Always verify current local regulations, as laws can change.

Will this magazine fit all S&W M&P 9mm pistols, including the M&P 2.0?

This magazine is designed to be compatible with the standard Smith & Wesson M&P 9mm platform. Compatibility with M&P 2.0 and compact variants may vary — we recommend confirming your specific model number before purchasing, or contacting our store team at Goodland Guns for guidance.

How does the quality of a ProMag magazine compare to OEM S&W magazines?

ProMag magazines are manufactured in the USA using steel construction and precision heat-treated chrome silicon wire springs — components designed to meet or exceed standard reliability benchmarks. While OEM magazines are always a safe baseline choice, ProMag's lifetime warranty and consistent quality control process make them a trusted aftermarket option for range use and everyday carry training.
