Who This Is For
This extended magazine plate is ideal for SIG P320 owners who want more rounds on tap without switching to a larger pistol platform — whether you're running USPSA/IDPA stages, training at the range, or building a home-defense setup where every round counts. It's also a smart upgrade for duty and competition shooters who demand reliable, consistent feeding from a reinforced base pad.

Frequently Asked Questions
Which SIG P320 magazines is this extension compatible with?
The Strike Industries EMP is designed specifically for SIG SAUER P320 double-stack 9mm magazines. It is not intended for .40 S&W or .357 SIG variants of the P320, so always confirm your magazine's caliber before installation. If you're unsure, check the markings on the base of your existing magazine or consult your P320's owner manual.
Is California's standard-capacity magazine law relevant to this product?
Yes — because this extension increases magazine capacity, California residents should be aware of state restrictions on magazines that hold more than 10 rounds. If your base P320 magazine is already at or near the 10-round limit, adding this +5 extension would result in a magazine that exceeds California's legal capacity. Always ensure your total loaded capacity complies with applicable state law before use.
How difficult is it to install the extended magazine plate on my P320 magazine?
Installation is straightforward and requires no special tools. You'll depress the existing base pad retention button, slide off the factory floor plate, transfer the spring and follower to the new Strike Industries extension body, and lock it in place with the included steel plate. Most users complete the swap in under five minutes. Strike Industries also provides installation instructions in the package.
