You won’t need any special tools to replace your factory components with the Sig P320 trigger kit. The Sig P320 Apex trigger is available with either a flat or curved trigger shoe to suit the shooter’s taste. Whether you choose the curved version or the Apex Flat Advanced trigger for Sig P320 you can expect to instantly improve the performance of your Sig with the installation of this kit. The Apex Flat Advanced trigger for Sig P320 is designed to reduce overall travel as well as the length of reset in your Sig P320. In most models, trigger pull weight will see a 30% reduction. X-Series owners will not see reduced trigger pull but will enjoy the benefits of reduced reset and overall travel.

What’s Sig P320 Apex Trigger Mean to the Shooter?

Reduced travel and length of reset allows the shooter to recover from each shot faster and more effectively. These improvements combined with quality trigger break and enhanced feel will bring the shooter better accuracy from first shot through repeated follow-ups. While the Sig P320 Apex trigger upgrade kit improves feel and responsiveness, it doesn’t sacrifice safety. The drop safety function of the Sig P320 remains as effective as it was from the factory.

  • Awesome & Easy

    Posted by Scott on 27th Apr 2020

    I purchased 2 of these. One was for a P320 X-Carry and the other was for an X-Five legion. I was hesitant because I originally saw the other review. After reading the review and seeing his complaint I noticed it clearly says does not work with manual safety in the description. Don’t let people who don’t know what they are doing influence your decision on this product. I watched the factory YouTube video about 5 times and it was super easy. Trigger is crisp and eliminates much of the slop. Super pleased with the product!!!!!

  • Will not work with Safety Switches

    Posted by Noah Forbes on 22nd Sep 2019

    If you have a Sig with a safety selection switch, you cannot use the bar. It will not seat long enough in the sear housing and it will not loop around the safety selector. And without the bar, you cannot utilize the travel limit bushing, making the only usable part the trigger. I do not believe this is written in the description anywhere on this page.
