Sig Sauer 8900029 P320 Grip Module Carry (Medium Grip Module) 9mm Luger/40 S&W/357 Sig, Black Polymer, Fits P320 (Manual Safety)

The Sig Sauer P320 Grip Module Carry in medium size gives you the foundation for a truly modular handgun. This black polymer grip frame is purpose-built for the P320 platform and accepts 9mm Luger, .40 S&W, and .357 SIG slide and barrel assemblies—swap uppers without changing your trigger or grip familiarity. If you carry or shoot a P320 and want the flexibility to run different calibers on the same platform, or if you're building out your P320 ecosystem, a quality grip module is where that modularity begins.

The medium size hits the sweet spot for shooters with average hand geometry—not too compact for control, not oversized for easy concealment. The integrated manual safety (rather than a trigger-actuated variant) is essential if your platform or training demands it. Black polymer construction keeps weight down while delivering the durability Sig's known for in duty and personal-defense applications.

This is a genuine Sig OEM part, not an aftermarket clone. When you're swapping caliber-specific uppers on your P320, you're working with a grip module engineered by the same team that designed the gun. Drop in your choice of upper assembly, and you've got a fresh gun without buying a whole new frame.

Frequently Asked Questions

Will this grip module work with all P320 uppers?

This grip module is designed to work with P320 slide and barrel assemblies chambered in 9mm Luger, .40 S&W, and .357 SIG. It will not function with other platforms or caliber-specific upper assemblies outside those three.

Does this come with a manual safety?

Yes. This grip module has an integrated manual safety, which is a critical safety feature for shooters who require or prefer it. If you need a trigger-safety variant instead, you'll want a different grip module model.

What's the difference between small, medium, and large P320 grip modules?

P320 grip modules come in small, medium, and large sizes to accommodate different hand sizes and preferences. Medium is designed for shooters with average hand geometry and is the most common fit. If you're unsure, hand-fit the medium at a range or counter before purchasing.

Is this an OEM Sig part?

Yes. This is a genuine Sig Sauer OEM component (part number 8900029) manufactured by Sig, not an aftermarket or third-party grip frame.
