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. 

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.

    320 trigger kit

    Posted by James Anderson on 9th Apr 2024

    I have been working on 320’s for 4-5 years now. This is by far the best kit to get a proper trigger reset. It’s not even close. Great, great, great product. It’s pretty easy for me to install. However, I wouldn’t let a novice do it without help. You guys are doing a great job. Thanks!

    So far so good

    Posted by Juan Cruz on 2nd Jan 2024

    I ordered the full kit including polished striker to keep the factory one as a spare. Install was pretty straight forward and accomplished everything in maybe 15-20mins despite working on my first FCU. everything installed was for the "competition feel" and it has changed the mushy feel of the trigger, reduced pull weight (nothing crazy), reduced take up and over-travel. So far dry firing it is great and the extra power return spring is a must imo. I've yet to live fire it but so far so good.

    P 365 Tactical Trigger kit

    Posted by David Giglia on 7th Dec 2022

    I've been shooting striker fired pistols for years. I have had many and the only thing that I've never liked is their trigger. That spongy rolling release of the striker is pretty consistent in all striker fired guns (SFG's) some worse then others. I just bought a new sig Sauer pistol and although the trigger was one of the better ones It still had that spongy multiple wall trigger. Enter the Tactical trigger. Bought it, installed it and I now have a trigger that is as close to a 1911 trigger as I have ever experienced. Guys I'm telling you It is AMAZING. If you have a typical SF trigger get this Kit. You will not be disappointed. Customer service is the best.If you have any problems installing it just call the number on the WEB site. You will speak directly to the guy who designed and created this kit. He knows his stuff and will walk you through getting it installed. Best striker fired trigger you'll ever have!

    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
