Description
The ProMag SIG20 is a 6-round replacement magazine built for the Sig Sauer P938 pistol. Chambered in 9mm Luger, this standard-capacity detachable mag is constructed from heat-treated steel with a black oxide (blued) finish and features an injection-molded follower for reliable feeding.
Designed as a direct-fit spare, the SIG20 drops into the P938’s magazine well with TIG-welded seams for strength and durability. It’s a practical addition to any P938 owner’s rotation for training, backup, or reload duty.
