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.

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!!

Part of the Adjustable Trigger Kit
The trigger came as part of the Grayguns trigger system & as stated in my review of the kit it makes the world of difference to the SOG P320 x 5 standard trigger. Awesome bit of kit & awesome service from Shooters Connection to go with it...AAA
