Frequently Asked Questions
Is this magazine legal to purchase and use in California?
Yes. This ProMag drum magazine is blocked to a 10-round capacity, making it compliant with California's magazine capacity restrictions. The drum body is designed to hold 50 rounds, but it has been permanently restricted so that no more than 10 rounds can be loaded, meeting state law requirements at the time of sale.
Will this magazine fit other Smith & Wesson SD-series pistols, such as the SD40?
This magazine is specifically designed and chambered for the S&W SD9 in 9mm. It is not compatible with the SD40, which is chambered in .40 S&W and uses a different magazine specification. Always verify caliber and model compatibility before purchasing a replacement or aftermarket magazine.
How reliable is the ProMag SD9 drum magazine for feeding and cycling?
ProMag engineers this drum magazine with a stamped and welded steel upper tower insert — mirroring the construction of factory magazines — along with a precision-molded follower and heat-treated stainless steel spring. These features work together to promote consistent feeding and reliable cycling. As with any aftermarket magazine, it's recommended to break it in with a few range sessions to ensure smooth operation with your specific firearm.
