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.
  • Grayguns original competition sear springs
  • Intermediate competition sear springs
  • Original soft competition trigger bar spring
  • New snappy-reset trigger bar spring 
  • Micro-polished, extended safety lever pin

  • Adjustable over-travel, stops at optimum trigger face angle

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.

Great trigger kit
Great trigger kit that came with competition and intermediate  spring sets. Easy to install and clean break at just over 3 lbs with a nice short rest. Definitely made the right choice going with the Grayguns trigger for my 320 X-Five!!

I wish I could say I loved it
I had the stock trigger for a P320 X5 Legion installed and had shot probably 4k+ rounds through it. It was a fine trigger but I caved to the hype and purchased the Grayguns comp. trigger. I've shot it twice now and I can honestly say I don't feel a difference. Is it lighter? Maybe? Crisper? I don't think so. It's okay I guess. Maybe I'll appreciate more as I shoot it more. Maybe it will "break in" and get better. Maybe...

Trigger Happy
Excellent product & excellent service. I have dealt with Shooters Connection in the past & find them extremely reliable & professional...i have no hesitation in dealing with them in the future. I have fitted these triggers to both my P320 x 5 Legion & my P320 x 5 and are more than happy with the product & results

Competition trigger
Reduced gritty pull with Legion trigger and dropped trigger pull from 3.5 to 2.5 lbs., very delicate but great feel.
