Product Overview

This trigger kit is designed for use with the stock internals and stock triggers of the P320® to maintain full safety and reliability and is compatible with all P320® variants (M17, M18, X series, including manual safety variants). Included in this kit is everything necessary to tune all key aspects of trigger performance: pretravel (distance from start to wall), sear engagement (wall/break feel and wall to break/reset distance), overtravel (amount of extra travel after the break), pull weight, and reset strength. In line with the P320 design, this kit is modular and each aspect can be addressed independently to achieve desired results. Using all parts provided in this kit, pull weight is reduced by up to 1#, total travel can be reduced by half, pretravel is light and smooth into a hard defined wall, wall to break/reset distance is reduced by less than half compared to the stock trigger, and the reset is quick and pronounced producing unparalleled performance and feel. See video below for trigger performance overview.

This kit includes an optional pretravel stop to reduce take up to the wall, our patent pending Sear Control Springs to minimise sear movement at the wall and also provide sear engagement adjustment if desired to reduce wall to break distance, an optional polished striker to provide the cleanest break feel, overtravel stop springs to minimize overtravel, an increased power trigger spring for an aggressive reset, and a reduced power striker safety spring for pull weight reduction and smoother pretravel. The stainless steel pretravel stop is fixed and set to provide to maximum allowable pretravel reduction while maintaining full striker safety margin (use only with the "576" marked trigger bar which is present in most guns purchased within the last few years, also available on the website if needed). The user desired wall/break feel can be achieved by installing 1 of the 3 provided Sear Control Springs. Overtravel is adjusted for the tolerances of your gun by installing 1 of the 3 provided overtravel stop springs. This complete kit can be installed and margin checked for safety and reliability in as little as 10 min by a knowledgeable gunsmith. See installation video below for detailed installation and margin inspection procedures. 

In stock and ships within 1 to 2 business days. Installation service is also available for $100 plus shipping costs through a local FFL that we have trained and certifed. Installation service is purchased independant of the website and a kit can also be purchased at the same time if preffered. Turn around time for installation is 2 to 3 business days once recieved. Contact us via email at to set up an installation.

Disclaimer: This kit should be installed by a certified and knowledgeable gunsmith. Due to tolerance variations between guns, safety and reliability margins should be inspected during installation and periodically thereafter during maintenance. Striker safety margin should be inspected to verify greater than 1/16 inch pretravel is present before the striker safety is defeated. Engagement of the sear to striker should be inspected to verify greater than 80% coverage of the sear interfacing surface. Although it is unlikely one or more Sear Control Springs provided in this kit will result in less than 80% sear coverage, a Sear Control Spring that provides greater than 80% coverage should be used in order to maintain full reliability. Tactical Trigger, LLC assumes no liability for installation or use of this product.

    P320 x5 trigger

    Posted by Mario on 25th Oct 2021

    Super impressed with the trigger. I hate the mushy "rolling break" of most striker guns including the x5 legion. Tactical is the 1st company with drop in parts that achieve a very crisp wall/break and very short reset. My X5 clocks in sightly under 3lbs now. A few gray guns x5 triggers I've handled are a tad lighter on the pull weight but very mushy and long reset

    This kit delivers on it's promises, lower pre-travel, lower reset, lower over travel, and lower pull weight! Highly recommended!!
