P320 Adjustable Straight Trigger System – Competition
The Grayguns Adjustable Straight 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, 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 Straight 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 straight trigger design, this is the most advanced drop in competition system available for all post/Voluntary Upgrade P320 models.

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.
