The ProMag Sig Sauer P938 9mm Luger steel blue magazine is a purpose-built upgrade for P938 owners who want reliable, high-capacity alternatives to factory mags. If you carry a P938 for personal defense or shoot it regularly at the range, you know that factory magazine capacity can feel limiting during extended training sessions or when you'd simply prefer more rounds on hand. ProMag's steel construction addresses that gap with durable aftermarket magazines engineered specifically for the P938 platform.
Built from heat-treated carbon steel with a black-oxide finish, these magazines resist corrosion and wear—important when you're rotating them through regular carry or range use. The internal spring is formed from heat-treated chrome-silicon wire, paired with an injection-molded follower for smooth, reliable feeding. ProMag manufactures these magazines in the USA, combining domestic production with proven materials science to deliver the dependability your P938 demands.
Available in both 6-round and 10-round capacities, the ProMag steel blue magazine lets you choose the configuration that fits your carry setup and training regimen. The 6-round keeps the compact profile P938 owners value; the 10-round significantly extends your round count for range days or extended drills. Either way, you're getting a robust alternative to factory magazines at a price that makes it easy to stock spares.
