Frequently Asked Questions
Will this drum magazine fit my Ruger Security-9 without any modifications?
Yes. This ProMag drum magazine is specifically designed to fit the Ruger Security-9 chambered in 9mm and drops in using the pistol's standard magazine well — no modifications required. It feeds from a blue steel upper tower that interfaces directly with the Security-9's feed ramp for reliable operation.
Why does a 50-round drum body only hold 10 rounds?
This magazine is configured for California compliance and other jurisdictions that restrict magazine capacity to 10 rounds. The drum uses the full 50-round body but is blocked and pinned to hold only 10 rounds of 9mm ammunition, making it legal for sale and use in restricted states while retaining the drum's distinctive profile.
How reliable is the ProMag drum magazine for range use?
ProMag drums are manufactured in the USA with precision-wound, heat-treated chrome silicon springs and injection-molded followers to promote consistent feeding. Every magazine undergoes quality checks during assembly, and the entire lineup is backed by a lifetime guarantee against manufacturer defects — making them a dependable choice for regular range sessions.
