Frequently Asked Questions

How is this magazine blocked to 10 rounds if the body holds 21?

ETS and compliant retailers permanently block the magazine internals so it cannot accept more than 10 rounds, while retaining the full 21-round external body. This gives P320 owners a natural grip length and familiar ergonomics without violating California's magazine capacity restrictions.

Will this magazine work with all SIG P320 variants?

This ETS magazine is designed to be compatible with the SIG Sauer P320 full-size and carry models chambered in 9mm. It is recommended to verify fitment with your specific P320 configuration, particularly compact or subcompact variants, before purchasing.

Is it safe to store this magazine fully loaded for extended periods?

Yes. ETS magazines are engineered with a rigid polymer construction specifically formulated to resist creep, meaning the feed lips and body will not spread or deform even when stored fully loaded for long periods of time. The material also resists degradation from temperature extremes, oils, and common solvents.
