Strike Industries EMPMPS Enhanced Polymer Magazine Plate for S&W M&P Shield – Adds 2 Rounds (9mm Luger) / 1 Round (.40 S&W) – Black Finish & Extra Grip

The Strike Industries EMPMPS Enhanced Polymer Magazine Plate for S&W M&P Shield is a purpose-built capacity extender that gives your compact carry gun more rounds on tap and a more comfortable grip. If you run a Shield in 9mm, this plate adds two rounds to your magazine; .40 S&W users gain one. It's the kind of practical upgrade that makes a real difference during training or when counting on your pistol for defense.

Strike Industries engineered the EMPMPS to feel like it belongs on an M&P Shield—the molded polymer surface matches the gun's texture and ergonomics, and the extended grip surface follows the Shield's contours rather than looking like an afterthought bolted on. Even with the added capacity, the plate sits low enough that it doesn't ruin the concealability that makes the Shield attractive in the first place. The impact-resistant polymer construction won't add unnecessary weight or bulk.

What sets this extension apart from budget alternatives is the included steel locking plate. Instead of a simple friction fit, the hook design on the lock plate provides solid mechanical retention—especially important when you've got a full magazine under spring pressure. Installation is straightforward: the steel plate threads on with a single set screw. Just remember the warning in the manual: once that screw is flush with the back of the body, stop tightening. Over-torquing can damage the extension itself.

The EMPMPS works with both standard 7-round (9mm) and 6-round (.40) factory magazines, and it's also compatible with extended-length factory magazines—though on those larger-capacity mags you'll see a visible gap between the plate and grip, and the factory spacer may need slight modification to sit flush. Not compatible with the Shield Plus. Everything you need comes in the box: the magazine plate, steel locking plate, and mounting screw.

Frequently Asked Questions

Will this work with my standard factory Shield magazine?

Yes. The EMPMPS is designed for the standard 7-round 9mm and 6-round .40 S&W M&P Shield magazines. It's also compatible with extended-length factory magazines, though you'll see a gap between the plate and grip on those larger-capacity mags.

Is this compatible with the Shield Plus?

No. The EMPMPS is not compatible with the M&P Shield Plus. It's made specifically for the standard M&P Shield.

What's included in the package?

You get the magazine plate extension, a steel locking plate with hook design for extra retention security, and the mounting screw needed for installation.

How tight should I install the set screw?

Tighten until the screw is flush with the back of the EMP body, then stop. Do not over-tighten beyond that point—over-torquing can damage the extension. If you're unsure about the proper installation, contact Strike Industries customer support or consult a local gunsmith.
