SIG P320 Grip Module X-Series Large, 9mm/40/357

SIG P320 Grip Module X-Series Large

This grip module assembly allows you to convert your existing P320 firing control unit into a full-size X-Series pistol. It's the modular platform that makes the P320 system so versatile.

Key Features

• Caliber Compatibility: Works with 9mm Luger, .40 S&W, and .357 Sig when paired with appropriate slides and barrels
• Size: Large module designed for full-size P320 frames (4.70" slide length)
• Material: Durable black polymer construction
• Modular Design: Simply install your P320 firing control unit to complete the conversion

What You Need to Know

This grip module does not include an extended magwell or internal weight. You'll need to source the appropriate slide and barrel assembly for your desired caliber separately.

Magazine Compatibility: Use magazines with the SIG Mark baseplate. This module is not compatible with magazines bearing "SIG SAUER" text on the baseplate.

The Modular Advantage

The P320's modular design means you can customize your pistol to suit different purposes—from duty carry to competition—by swapping grip modules, slides, and barrels. This grip module is a key component in that system.
