Note: These are Sig's original P938 7rd magazines (MAG-938-9-7) and will not work in the P938 Legion.

The correct part number for Sig's new P938 Legion magazine is MAG-938-9-7-LEGION.

The extended magazine protrudes approx two thirds of an inch below the magazine well and has an X-Grip adapter to allow for a better grip on the pistol.
