Sig Sauer 8901482 Black Polymer Fits P320/M17/M18

The Sig Sauer 8901482 is a black polymer grip module designed to work with your P320, M17, or M18 platform. If you're running a P320 with a manual safety firing control unit, this module lets you swap calibers and configurations without replacing your entire platform. It's the modular approach that makes the P320 system so versatile—change grips, change calibers, keep what works.

This grip module accepts 9mm Luger, .40 S&W, or .357 SIG caliber setups, so long as you pair it with the matching slide and barrel for your chosen cartridge. That modularity is core to the P320 ecosystem: your trigger group stays consistent, your ergonomics adapt to your mission, and your platform grows with you. Whether you're building a carry gun, a duty rig, or a range toy, this module gives you the foundation to do it.

Built from black polymer, it's durable enough for serious use and light enough that it won't slow you down. The module is straightforward to install—if you've done any P320 work before, you'll have this sorted in minutes. It's a no-nonsense part that does exactly what it's supposed to do: give your firing control unit a proper home in a new caliber or size configuration.
