Strike Industries EMPP320 Enhanced Magazine Plate +5rd Extension for Sig P320, 9mm Luger, Black Polymer

The Strike Industries EMPP320 Enhanced Magazine Plate is a +5-round extension designed to boost the capacity of your Sig P320 9mm magazines. If you run a P320 for duty, competition, or serious practice, adding five rounds per magazine means fewer reloads downrange and more rounds on target. Strike Industries engineered this plate with a focus on real-world use: a slow-drag, snag-free design that plays well with holsters and gear, plus a steel locking mechanism that keeps the extension locked in place during heavy use.

Built from black polymer, the EMPP320 maintains the aggressive, unified look that defines Strike's P320 ecosystem. This isn't a bulky add-on—it's a purpose-built extension that sits flush with your pistol's proportions. Whether you're stocking mags for a carbine course, competition circuit, or duty carry, the extra capacity makes a real difference without the weight penalty of a completely new magazine.

Strike Industries has built a reputation for smart, no-nonsense upgrades that shooters actually use. The EMPP320 follows that formula: solve a genuine problem (limited factory capacity), engineer it cleanly, and deliver a product that fits how shooters actually work. The included steel locking plate ensures your extension stays put through thousands of rounds and countless reloads.

Frequently Asked Questions

Will this extension work with my Sig P320 holster?

The EMPP320 is designed with a snag-free profile that pairs well with standard P320 gear. That said, holster fit can vary by model and manufacturer—if your rig was cut tight to the original magazine dimensions, you may need to verify clearance or swap to a holster rated for extended mags.

What's included with the extension?

The EMPP320 comes with the polymer extension plate and a steel locking plate that secures it to your magazine.

Can I use this for duty or serious carry?

Yes. The steel locking mechanism is engineered to hold under the demands of daily carry, training, and duty use. The snag-free design means it won't catch on your draw or on other gear.

How many rounds does this add to my P320 mags?

The EMPP320 adds 5 rounds to each magazine it's installed on.
