Promag P938: Reliable Concealed Carry 9mm Magazine Solution

Concealed carry is a balance between preparedness and practicality. For many shooters the magazine is one of the simplest upgrades that directly impacts reliability, reload speed, and how comfortably a handgun carries every day. A thoughtfully chosen spare magazine should be predictable in fit, durable in function, and wallet-friendly so you can carry confidence without breaking the bank.

PROMAG SIG P938

When you’re running a subcompact like the Sig P938, magazines designed specifically for that platform matter. The PROMAG SIG P938 is built to fit a Sig P938 firearm and will hold up to six 9mm rounds. At a price point of $17.99, this magazine offers a direct, economical path to having an extra loaded magazine on hand for training or carry rotation. Shop this product here: Shop this product.

Why this magazine matters for concealed carry

The Sig P938 is a popular choice among concealed carriers due to its compact footprint and comfortable ergonomics. A dedicated magazine that fits that platform ensures feeding geometry and spring tension are matched to the pistol’s magazine well. The PROMAG SIG P938 is explicitly designated to fit the Sig P938 and holds six 9mm rounds, which aligns with the pistol’s design and intended use as a short-barreled defensive handgun.

Design and fit

Promag’s replacement magazine follows the dimensions and catch geometry required by the P938. That matters because even minor differences in magazine dimensions can cause failure to lock properly, misfeeds, or difficulty in seating the magazine quickly during a reload. This magazine’s six-round 9mm capacity matches the firearm’s original intent: compactness and concealability without dramatic increases to grip length or printing under a jacket.

Why six rounds of 9mm?

The six-round capacity is a practical compromise. For subcompact pistols, adding more rounds often requires extended baseplates that affect concealment and carry comfort. A six-round 9mm magazine keeps the gun short and easy to hide while leveraging the ballistic and handling advantages of the 9mm cartridge—manageable recoil, widespread ammo availability, and modern defensive bullet performance.

Performance considerations

Performance in the field comes down to consistent feeding, spring tension over time, and drop-free reliability during reloads. While aftermarket magazines can vary, choosing one explicitly matched to the Sig P938 reduces guesswork. For everyday carry and range days, having an extra PROMAG SIG P938 magazine loaded and rotated into service every few months keeps springs healthy and reliability predictable.

Training and carry routines

We recommend treating aftermarket magazines the same as factory magazines: run them in the gun, check for fit and lockup, and include them in dry-fire and live-fire drills. That familiarity reduces surprises if you ever need to change magazines under stress. For a compact defensive setup, carry one in the gun and one as a spare in an easily accessible pocket or pouch.

Durability and maintenance

Magazine maintenance is straightforward: keep the body free of debris, periodically disassemble if designed to do so, and inspect the spring and follower for wear. Given the low price point of $17.99, turning magazines over every few years or replacing them after heavy use is cost-effective. The PROMAG SIG P938’s design emphasizes compatibility; routine cleaning and proper storage will keep it serviceable for many carry cycles.
