The Grayguns P320 Competition Trigger System for the SIG Sauer® P320 is a drop-in, enhanced trigger package with competition sear for your P320 that reduces trigger weight to about 4 pounds while preserving all mechanical safety values. Shoot with a straight face (P320ST), or go with the curved-face (P320CT) design.

Specifically designed for guns that have gone through SIG’s Voluntary Upgrade Program.

Our triggers are externally comparable in appearance to the factory part.

Our SIG Sauer P320CT or P320ST Competition Trigger System can now be installed by an armorer, gunsmith or skilled individual who is familiar with the P320 fire control unit. The kit is specifically designed for guns that have gone through SIG’s Voluntary Upgrade Program. The kit includes the following elements:

  • Your choice of straight (P320ST) or curved (P320CT)
  • Precision-ground Grayguns custom sear, polished and finished in hard nickel PTFE. Specifically designed for competition or range use only.
  • Grayguns competition sear springs
  • Grayguns competition trigger bar spring
  • Over-travel stop tube
  • Micro-polished, extended safety lever pin

The Grayguns P320 Competition Trigger System yields superior trigger pull results while supporting the voluntary upgrade’s enhanced reliability and rough handling performance qualities. It yields a trigger pull weight of approximately 3.5 to 5 pounds. The kit with included competition sear is designed exclusively for competition or range use only.

Fit Guide

Fits all variations within the P320 (upgraded) system. Including all sizes, TACOPS Carry, X-VTAC, X-Carry, X-Five and RX versions.


This product was previously referenced as the P320 competition kit including our Practical Enhanced Leverage Trigger (PELT).


These parts are intended for installation by a qualified armourer or gunsmith. In some cases professional fitting will be required by a trained, qualified armorer/gunsmith who is very familiar with the pistol’s action. This is due to the varying tolerances present in all mass-produced firearms. Although kits fit with no issues in a great majority of pistols, Grayguns is unable to guarantee perfect functionality in every instance. Grayguns does offer installation services for all parts kits we offer.

Turns the 320 game up. Love the feel of this trigger. Still has a bit more creep than I'd hoped though.

Awesome trigger
I purchased this kit because I wasn’t quite happy with the factory trigger in my P320 X-Carry. It arrived quickly, which is always an extra star for any place I order from. Installation difficulty level I’d put at a 7 out of 10, and most of that is due to my over-sized sausage fingers. I don’t have a trigger weight gauge, but boy did it lighten up the trigger! Smooth as well making putting follow up shots on target much faster. It does have a little creep to it, which I’m not quite sure if it was intentional or not. But all and all I am happy with my purchase.

Amazing Trigger
I was looking for something that would drastically change the pull weight and with this I found it. Short take up and reset and pull weight is extremely low. I would recommend this product to anyone with a p320.

Short take-up and reset with a lighter trigger.  This trigger is well worth the money!
