P320 trigger

The P320 Adjustable Trigger – in either straight or hybrid design – can be installed by most owners (see below), a SIG armorer or gunsmith. If you prefer Grayguns to install your trigger, we offer this service.

Installation includes additional internal polishing as necessary, armorer’s inspection, sight regulation and test firing by our gunsmiths. Of course, you have the option to add-on finishing, sights or our custom FAT guide rod as appropriate.

Triggers are specifically designed for guns that have gone through SIG Sauer’s Voluntary Upgrade Program.

All of our work can be completed on any P320 variant, including the X-Five.

About this Specific Installation Service

With our P320 Adjustable Trigger design, we have found customers who install the trigger themselves – or have it installed locally by a SIG armorer or gunsmith – get results similar to having a Grayguns technician complete the install.

That said, many customers do prefer the trigger to be installed by our team, so we have brought back this option.
