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)

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.

A Game Changer
Put this kit in a M17. The trigger in that gun is now as good as the one in my X5 Legion.

best 320 trigger setup period
was very easy to install and will give you a 1911ish trigger pull on your 320.Highly recommend but its a good idea to have a lot of trigger training so as not to have a mishap.Not for the amatuer or just gun enthusiast.

Sig m17
Incredible !! The trigger pull on my M17 is now lighter than the one on my Legion. Definately recommend it for competition guns. Too light for carry.

Nice improvement
I wish I could give 4 1/2 stars but not allowed. Trigger is vastly betterbetter in every regard except one. From the wall to the break there is an unacceptable amount of mushy feel then clean break. Total weight dropped about 3 lbs but the distance from wall to break actually increased. I'd  gladly pay $50 more for this kit if this was substantially improved. Was it worth $134 which included shipping? Absolutely. I would rather pay $185 for a kit without the statedissue. Would recommend but do recognize that it could be improved.
