When selecting a spare magazine for concealed carry or home defense, reliability and compatibility are non-negotiable. A compact pistol like the Sig P938 demands magazines that seat cleanly, lock up consistently, and maintain a reliable stack under everyday conditions.
PROMAG SIG P938 is a drop-in replacement magazine designed specifically to fit the Sig P938 platform and hold up to ten 9mm rounds.

Compatibility and materials
The magazine is engineered to drop into the Sig P938 with minimal break-in. Promag’s focus on fitment reduces feeding issues common with poorly matched aftermarket magazines. While the P938 is traditionally chambered for .380 or 9mm depending on model, this specific offering supports a 9mm loadout — an attractive choice for users seeking the wider availability and terminal performance of 9mm in a subcompact package.

Tactical considerations
For personal security use, a reliable ten-round magazine increases rounds on tap without significantly altering concealability. The advantages of 9mm — controllability, magazine capacity, and ammunition selection — make this magazine a practical option for everyday carry or as a ready spare for home defense. Promag’s reputation for producing aftermarket components means these magazines are built with serviceability in mind, and “Various” models allow shooters to choose baseplate or follower options that suit their reload and carry preferences.
