Frequently Asked Questions
Is this magazine legal to purchase and use in California?
Yes. Although this magazine features a 50-round drum body, it is blocked and pinned to a 10-round capacity, making it fully compliant with California's magazine capacity restrictions. It is sold here specifically as a California-compliant product. Always verify your local ordinances, as some cities or counties may have additional restrictions.
Will this drum magazine fit all P320 variants, including the Compact and Carry models?
This ProMag drum magazine is designed to fit the Sig Sauer P320 chambered in 9mm. Compatibility may vary between P320 frame sizes — it is primarily intended for full-size P320 models. We recommend verifying fitment with your specific P320 variant before purchasing, as grip module differences between Compact, Carry, and Full-Size frames can affect seating and function.
How reliable is the ProMag P320 drum magazine for range use?
ProMag magazines are manufactured in the USA and undergo multi-step quality control checks at every stage of assembly. The heat-treated stainless steel spring and injection-molded follower are engineered to minimize feed failures and maintain consistent round presentation. While aftermarket magazines may require a break-in period of 50–100 rounds, users generally report dependable performance for range and training sessions.
