The Grayguns Adjustable 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 as low as 4 pounds while preserving all mechanical safety values. Includes our adjustable straight trigger or hybrid (Slight Curve) with built-in over-travel adjustment.

Specifically designed for P320s with current fire control unit components, or those who have gone through SIG’s Voluntary Upgrade Program. This system is for competition or range use only.

The new Grayguns P320 Adjustable Competition Trigger System delivers the unequalled smooth feel and hot performance of our custom action work in a cleverly engineered drop-in kit.  

Paired with Bruce Gray’s exclusive trigger design, this is the most advanced drop in competition system available for all post/Voluntary Upgrade P320 models.

The P320 Competition Adjustable Trigger System is intended for installation by an armorer, gunsmith or skilled individual who is familiar with the P320 fire control unit. 

The kit includes the following exclusive Grayguns elements:

  • Our newly designed straight trigger with built in over-travel adjustment
  • Precision-ground custom sear, polished and finished in hard nickel PTFE. Specifically designed for competition or range use only.

  • Micro-polished, extended safety lever pin

Fit Guide

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


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. Note – The safety lever spring is no longer needed in the P320, and is not included in the kit.

Simply an excellent trigger
We first prove the Apex trigger. That do not operate as advertised. The only thing they have good is the short travel. Now we change to the Grayguns Comp. Trigger and it was simply excellent and operate as advertised. Trigger pull go from 5.25 to 3.5 pounds with a short travel. Finally, the service of Shooter Connection was precise. Receive the trigger on 3 days to P.R.. Thanks.

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.
