Key features and fit

This PROMAG SIG P938 magazine is purpose-built for the Sig P938 and accepts six 9mm rounds, matching the compact nature of the pistol. For shooters who prefer the ballistics and manageable recoil of 9mm, this mag provides a straightforward way to keep an extra load on-hand without adding bulk. The product carries a clear price point at $19.99, making it an affordable backup or training spare for everyday carry owners.

Why the 9mm capacity matters

Nine-millimeter ammunition combines effective terminal performance with controllable recoil in a small-frame pistol. A six-round magazine for the P938 keeps the pistol’s slim profile while offering a full reload option that mirrors the pistol’s original capacity. For range work, having identical-capacity spares simplifies drill setup and reduces variables when practicing draw-and-reload drills.

PROMAG SIG P938 is listed to fit the Sig P938—confirm fitment with your specific model before purchase.
