Sig Sauer P320 Black Flat Trigger, 90° Break, Fits Sig P320

The Sig Sauer P320 Black Flat Trigger is a direct replacement trigger designed specifically for the Sig P320 platform. If you're running a P320 and want a cleaner, more predictable break than the factory setup, this flat-faced trigger delivers a 90-degree break that many shooters prefer for both precision work and defensive use. It's a straightforward upgrade that can improve your control and consistency without requiring gunsmithing or permanent modifications.

Sig Sauer manufactures this trigger to the same exacting standards as the original P320 parts, so you're getting the reliability and fit you'd expect from the factory. The flat face gives you a consistent, centered contact point with your trigger finger, which translates to more repeatable trigger breaks—especially useful if you're working on accuracy at the range or want a more refined feel for carry. Installation is a straightforward swap; no special tools or expertise required if you're comfortable with basic P320 maintenance.

Whether you're tuning a competition gun, refreshing a well-worn duty P320, or simply upgrading your carry piece, this trigger gives you an easy way to personalize your pistol's action. The black finish matches the standard P320 aesthetic, so it won't stand out visually—just performs better where it counts.

Frequently Asked Questions

Will this trigger work on my Sig P320?

Yes—this trigger is engineered as a direct replacement for the Sig P320. As long as you're running a standard P320 (any caliber or frame size in the P320 platform), this trigger will fit and function.

What's the difference between a flat trigger and a curved one?

A flat trigger face gives you a larger, flatter contact surface with your finger, which many shooters find more natural and easier to control for precision shooting. The 90-degree break angle on this trigger is also a common preference for shooters who want a crisp, predictable action.

Do I need a gunsmith to install this trigger?

No. The P320 is modular and user-friendly; trigger replacement requires only basic familiarity with P320 disassembly. If you've ever cleaned your P320, you can swap this trigger yourself. That said, if you're not comfortable working on your own gun, a gunsmith can do the job quickly.
