Most Helpful Positive Review greatly improves trigger feel
I typically avoid third party after market triggers on pistols. However, this upgrade is direct from sig sauer. Same trigger found on the X series and I believe it’s basically same as the legion series 226. Improves trigger pull and it’s an OEM part. I had the apex trigger previously. It was fine. T...

flat trigger for Sig Sauer P320

When you shoot, you feel a little recoil in your finger, but it's very comfortable and you can shoot

works as designed

by Mike V, Verified Owner from FL, United States Written on May 22, 2025
Great trigger upgrade. Fairly easy to install without tools. Followed a youtube video and got it installed in under 20 min. It definitely shortens the reset, and i love the feel of the flat face.
Almost went with an aftermarket trigger, but i figured stock is best. Plus you cant beat OP's pricing and fast delivery :)
Pros:
  • EASY INSTALL
  • stock parts
Cons:
  • not adjustable
Would recommend: Yes

Sig Sauer P320 flat triger

by Illya Lakusta, Verified Owner from NJ, United States Written on April 13, 2024
It fits very well for the sig P320, it looks comfortable and feels more comfortable to descend. As a result, accuracy increases when shooting, I recommend it. Installation instructions can be found on YouTube

p320 Flat trigger

by doccnf, Verified Owner from PA, United States Written on February 4, 2024
As always, Optics planet provides great products and good-to-great prices with timely delivery. This purchase was no exception. I have purchased most of my upgrade products and maintenance parts for the p320 through Optics Planet and will continue to do so. I prefer the flat trigger to the standard curved for the p320. The press seems easier and straighter and the break seems cleaner with the flat vs curved trigger.

go with oem parts

by JB, Verified Owner from RI, United States Written on March 25, 2021
Great flat trigger to upgrade your sig p320. Always go with OEM parts when possible. Improves trigger pull. Very easy to install...just a bit of wrestling with the trigger spring. If you remove the fire control unit, you can install this. Highly recommend.
