The ProMag Magazine for Sig Sauer P938 9mm is a steel-built aftermarket option designed to extend your carry gun's on-range utility. The P938 is compact and purpose-built for concealed carry, but its factory magazine capacity limits how long you can shoot before reloading. ProMag's steel magazines come in both 6-round and 10-round configurations, giving you flexibility for practice sessions, competition, or everyday carry depending on your needs and local laws.
Built from heat-treated carbon steel with a durable black-oxide finish, these magazines are engineered to resist corrosion and handle the demands of regular use. The internals—a heat-treated chrome-silicon spring and injection-molded follower—are designed for reliable feeding and long-term durability. ProMag manufactures these magazines domestically, and they're purpose-designed for 9mm Luger ammunition only, ensuring proper fit and function in your P938.
If you're a P938 owner who puts rounds downrange regularly, having a spare magazine or two with higher capacity gives you more time between reloads and makes practice more efficient. The all-steel construction means these magazines will handle the rigors of the range without the wear concerns that sometimes plague thinner-walled alternatives.

Frequently Asked Questions
Will this ProMag magazine work in my Sig Sauer P938?
Yes, this magazine is specifically designed for the Sig Sauer P938 9mm. However, make sure you select the capacity option you need—6-round or 10-round—and verify compliance with your local carry laws if you're choosing the higher-capacity version.
What's the difference between the 6-round and 10-round capacity?
Both are available for your P938. The 6-round matches the standard factory capacity, while the 10-round extends your shooting time between reloads, making it popular for range practice. Choose based on your intended use and any legal restrictions in your area.
What ammunition does this magazine accept?
This ProMag magazine is designed exclusively for 9mm Luger ammunition. Do not attempt to use it with other calibers.
How durable is the black-oxide finish?
The black-oxide treatment is applied to protect the heat-treated carbon steel body against corrosion and premature wear from regular use. It's a proven finish for steel magazines, though routine cleaning and maintenance will extend its life.
