Frequently Asked Questions

Will this magazine fit all SIG Sauer P320 variants?

This ProMag magazine is designed to be compatible with the SIG Sauer P320 chambered in 9mm. It is engineered to fit standard P320 frames, including full-size and carry configurations. If you own a compact or subcompact P320, we recommend verifying fitment before purchase, as grip frame compatibility can vary with the modular P320 platform.

Why does this magazine have a 32-round body but only hold 10 rounds?

California law restricts magazine capacity to 10 rounds. This magazine uses a full-size 32-round body that has been permanently blocked to hold a maximum of 10 rounds, keeping you legally compliant while maintaining the ergonomic feel and full grip length of a standard-capacity magazine. The blocking is a permanent alteration — this is not a standard magazine modified in the field.

How does the ProMag lifetime guarantee work?

ProMag stands behind every magazine they manufacture with a lifetime guarantee against defects in materials and workmanship. If your magazine fails due to a manufacturing defect at any point during its lifespan, ProMag will repair or replace it at no cost to you. Normal wear and tear, modifications, or damage from improper use are not covered under the warranty.
