Superior Engineering, Tactical Performance

The SIG P320 line has made waves in the firearms world, serving as the foundation for the U.S. Army’s M17 and M18 service pistols. This suppressor-ready, extended-capacity model builds on that proven performance with enhancements aimed at tactical and competition shooters alike. The threaded 4.6” barrel makes it easy to attach your favorite suppressor or compensator, reducing muzzle blast and recoil for a smoother shooting experience.

The Moss Green slide finish adds corrosion resistance and tactical appeal, contrasting beautifully with the Gray X-series polymer grip module. This X-series frame offers improved ergonomics, enhanced undercut, and aggressive texturing for superior control in high-stress situations or extended range sessions.

Modularity and Customization

One of the defining features of the SIG P320 series is its modular fire control unit (FCU), which legally constitutes the firearm. This means the user can easily swap grip modules, slides, and barrels to transform the P320 into a full-size, carry, compact, or even subcompact variant—all using the same serialized FCU.

Whether you’re looking to reduce the footprint for concealment or increase the frame size for a duty role, the P320’s modular design supports nearly limitless customization. You can also upgrade with custom grip textures, aftermarket triggers, or red dot optics to create a platform that fits your exact needs.

Suppressor-Ready Performance

Suppressor compatibility is becoming an essential feature for professionals and enthusiasts alike. With its threaded barrel (½x28 threads), this SIG P320 model is ready out-of-the-box for sound suppression. The thread protector ensures that the barrel threads are shielded when not in use. When paired with a suppressor, this firearm reduces sound signature, improves muzzle control, and enables stealth shooting in tactical environments.

Advanced Optics Compatibility

This P320 is optic-ready, making it easy to mount reflex sights such as the SIG ROMEO1 PRO, Trijicon RMR, Holosun, or Leupold DeltaPoint Pro. With today’s shooters moving toward red dot optics for faster target acquisition, the ability to quickly co-witness or mount your preferred sight system makes this handgun adaptable for every use case—from duty to competition to home defense.

Combined with the X-RAY3 day/night sights, shooters have enhanced visibility in all lighting conditions, ensuring fast and confident target engagement even without a red dot.

High-Capacity Firepower

With its 21-round steel magazine, the SIG P320 TWO-TONE offers more than enough firepower to handle defensive situations, competition scenarios, or extended range time without frequent reloads. The extended capacity is especially useful for tactical roles, home defense, and those who prefer more rounds before reloading.

Extra magazines are widely available and easy to find, with options ranging from 17-round standard mags to 21- and 30-round extended options for duty or tactical setups.

Ergonomics and Control

This version of the P320 utilizes the X-Series grip module, which is optimized for improved control, recoil management, and shooter comfort. Its aggressive grip texture provides a secure hold in wet, muddy, or gloved conditions. The beavertail and high undercut trigger guard allow for a high grip angle and reduced muzzle flip—ideal for fast follow-up shots.

The trigger on the SIG P320 is a standout feature: crisp, flat-faced, and consistent, with a short reset that promotes faster shooting with improved accuracy. The internal striker-fired system offers reliability with fewer moving parts than traditional hammer-fired pistols.
