Our New P320 Trigger Bar Kits

So, somewhere around the exact same time everything blew up on the internet about dropping the P320, or hitting it with a hammer [which by-the-way is NOT a legit test of the system’s vulnerability to discharge due to impact], Apex had an all new product ready to go.

Yup, we were all set to release our patent pending Apex Forward Set Trigger Bar for the P320. That is until all hell broke loose. Because we’re Apex, and we’re kinda the guys (and gals) that do legitimate testing on our products, we put this new trigger bar on hold until Sig announced their safety upgrades and we had a chance to test those upgrades with our trigger bar.

As you probably know, we redesigned our three P320 triggers to work in the new upgraded version of the P320. The result of that effort is shown below. You will note that the Flat-Faced Action Enhancement Trigger actually decreased the pull weight by approximately 18%. Yeah, that surprised us, too.

Keep in mind that this testing was done on digital trigger scan device which maps out what takes place during the entire trigger pull. And the results above are from a brand new P320 in a stock configuration with a measured trigger pull weight of 8.0 lbs. Your results will likely vary depending on factory tolerances and how well broken in your pistol is.

Back To That New Trigger Bar

The Forward Set Trigger Bar project began in early fall of 2016 when our first prototype was done. By the time last year’s NRA Show took place we had a revised prototype in a display gun to share with P320 fans stopping by our booth, letting them know we were on track for a summer release.

And then Sig-gate happened (everything gets a “gate” these days).

After we got our hands on a couple factory upgraded P320 models we began testing the trigger bar in the stock pistol as well as with the three new versions of our own P320 triggers. It took a little time to dial everything in based on the changes we saw in the upgraded P320’s stock trigger performance, but we are finally ready to release these new kits.

The chart below outlines how the Forward Set Trigger Bar Kit performs with each Apex trigger. For those of you who already own one of these new triggers, you will be able to purchase the Apex Forward Set Trigger Bar Kit (Part# 112-041) to pair with your Apex trigger.

You can also use the Sig Sauer factory curved trigger with the Apex Forward Set Trigger Bar Kit for a 20% reduction in overall trigger travel and about a 10% reduction in trigger pull weight. HOWEVER, our kit has not been tested with any other aftermarket parts and we do NOT recommend their use with anything but the Sig factory curved and new Apex triggers. Also, to be clear, these kits are specifically for use in the Sig P320 with the full complement of factory safety upgrades offered through Sig’s voluntary safety upgrade.

If you do not have an Apex trigger in your P320 and you want to upgrade with both Apex products, we have combined them into three kits. They are

Part# 112-030  –  Apex Forward Set Trigger Bar Kit w/ Flat-Faced Action Enhancement Trigger

Part# 112-031  –  Apex Forward Set Trigger Bar Kit w/ Flat Advanced Trigger

Part# 112-032  –  Apex Forward Set Trigger Bar Kit w/ Curved Advanced Trigger

Well, there you go. Four new Apex products for P320 owners to upgrade their pistol. Installation is fairly straight forward, as you would expect, and our install video is being edited now. We hope to have that up on YouTube shortly.

These new products will be available for Pre-Order on Monday, February 12 and will begin shipping on Monday, February 19. And, as always, Apex’s customer service team is happy to assist you should you have questions about which kit to order or problems during installation.

    021 flat trigger fit for new trigger bar?

  2. paul - February 6, 2018 @ 12:10 pm

    No, these kits are for use in the factory upgraded P320 models and for use with our new triggers. The older versions, including the 112-021, are no longer available.

  3. David H - February 6, 2018 @ 12:43 pm

    Will these work with non upgraded P320’s? I have both original versions of the Apex flat trigger and the Sig flat trigger which I am still deciding which I shoot the best with. I love the trigger pull as-is but I’d love to feel these improvements!

    Thanks and keep up the good work!!

  4. paul - February 6, 2018 @ 12:53 pm

    Our new Trigger Bar Kits, and our three updated Triggers, are specifically for use in the factory upgraded versions of the P320 pistol.

  5. Larry - February 6, 2018 @ 1:16 pm

    Will this work with the sig straight trigger in the new p320 x carry or would I have to buy the apex trigger to go with it?

  6. Michael B. - February 6, 2018 @ 1:20 pm

    How much are the trigger bars going to cost?

  7. paul - February 6, 2018 @ 1:26 pm

    It works with the factory curved trigger but we have not tested it with the Sig factory version of the flat trigger. Once we do we’ll be able to update the you.

  8. paul - February 6, 2018 @ 1:27 pm

    112-041 $79.95
    112-030 $119.95
    112-031 $124.95
    112-032 $124.95

  9. Javier G. - February 7, 2018 @ 2:19 pm

    I recently purchased, thanks to your amazing exchange program, two new Flat Advanced triggers. I am very interested in your new trigger bar, however, I can not find any videos either showing how it works or how to install it, specially since you have added two new parts in the form of the spring and the small black buffer. Please, put out some videos with real instructions so we can discern whether or not this a viable option for our guns. Thank you.

  10. paul - February 12, 2018 @ 11:41 am

    The installation video is being edited right now.

  11. Dave - February 14, 2018 @ 5:41 pm

    With the product name, it sounds like this lengthens the distance from grip to the trigger face. Is that the case?

  12. paul - February 17, 2018 @ 12:39 pm

    It does not other than change the curved face of the trigger to a flat face. There is that smaller bit of length. But the trigger mechanism is not overall set forward in the trigger guard. That is not what the “Forward Set” refers to in the name of the trigger bar.

  13. David White - February 20, 2018 @ 4:23 pm

    I previously purchased the advanced flat face trigger and was somewhat disappointed because it did not break crisply. Just today I received and installed the forward set trigger bar kit with the advanced trigger and am very pleased with the now crisp trigger. I did measure the trigger pull at 5.5 lb. This pull weight was very consistent. I am very pleased with these purchases!

  14. paul - February 22, 2018 @ 11:51 am

    Glad you like the new trigger bar kit. But just for clarity, the trigger itself is not designed to change the characteristics of the break.

  15. This guy - April 3, 2018 @ 12:41 pm

    Will the forward set trigger bar work with the safety version of the 320?

  16. paul - May 16, 2018 @ 9:13 am

    From our website: “Not for use in Thumb Safety models of the P320.”

  17. Mariusz - August 23, 2018 @ 2:38 pm

    So, do I need to first have my 320 sent to Sig for the upgrade before I get the trigger bar?

  18. paul - September 19, 2018 @ 8:36 pm

    Yes, the trigger kits for the P320 are designed for the upgraded models.

  19. Jared - October 1, 2018 @ 2:09 pm

    So I bought the sig p320 m17 does this come with the upgrade and if so what “should” I buy for a new trigger and how much would a flat trigger cost. (For everything)

  20. paul - October 4, 2018 @ 8:06 am

    The M17 was released after the factory’s voluntary upgrade took place so there should be zero issues with running one of our kits triggers in that model. Which option you go with in terms of a kit trigger is up to you but the most popular option is the 112-031 which has our Forward Set Trigger Bar and the Flat Advanced Trigger. MSRP is $124.95. Our kits with the trigger bar will NOT function correctly in the M17 models with a thumb safety.

  21. tim whitehouse - November 19, 2018 @ 10:55 am

    i bought my p320 used at cabelas earlier this year. how can i tell if it has been upgraded?

  22. paul - November 19, 2018 @ 10:59 am

    To get absolute confirmation we recommend contacting Sig’s customer service and provide them with the pistol’s serial number. They should be able to confirm whether or not it’s upgraded.

  23. Carlos - December 5, 2018 @ 3:57 pm

    Does the Part# 112-032 – Apex Forward Set Trigger Bar Kit w/ Curved Advanced Trigger be used in the P320 subcompact?

  24. John Crouch - December 5, 2018 @ 7:02 pm

    Is there any plans for a trigger bar for the old non upgraded units ?
    I have 2 of the old 112-020 flat triggers.

  25. paul - December 10, 2018 @ 2:29 pm

    None whatsoever. We strongly advise having your pistol upgraded with the added safety features from Sig Sauer.

  26. paul - December 10, 2018 @ 2:30 pm

    No, our trigger bar will not function in the subcompact grip module due to tighter internal dimensions. You cna run the triggers though.

  27. Ben - December 20, 2018 @ 5:58 pm

    Will your trigger bar work with the xcarry flat trigger?

  28. Alexander - December 22, 2018 @ 4:51 am

    Are you working on a version of your kit for the manual safety M17 pistols?

  29. Mike T - December 23, 2018 @ 6:17 am

    I purchased the Apex flat trigger and loved it on my 320 before the voluntary recall and after getting the gun fixed by Sig, I can’t use that trigger. So will the bar kit allow me to use the old Apex trigger? If not, do you have any kind of upgrade program for previous customers?

  30. paul - December 24, 2018 @ 2:00 pm

    See the notice here:

    Contact Apex Customer Service, we are offering free replacements of our original triggers for the P320.

  31. Craig Broadway - January 4, 2019 @ 7:36 pm

    I am a new Sig P320 owner who purchased the gun with the factory upgraded trigger.
    I reside in Toronto, Canada. I want to purchase a Flat Face Trigger with the Apex Forward Trigger Bar Kit. I will only be shooting this gun at the range as we cannot legally conceal carry. Can you advise whether part # 112-025 or 112-26 paired with either 112-030 or 112-031…which would be the best combo. The main question is whether you ship to Canada.
    Thank you for your time in answering my questions.
    Best Regards,

  32. scott - January 8, 2019 @ 6:17 am

    We are unable to ship to Canada. You would have to go through Brownells or find a shop up there that carries them from an exporter.

    If you go with one of the advancing triggers, you will see a reduction of nearly 2 lbs from the stock trigger pull. If you add our trigger bar, that bar will decrease leverage and bring the trigger pull weight back up by nearly 1 lb, but will shorten the trigger stroke movement to fire. It’s sort of a give an take.

  33. B.sosa - January 23, 2019 @ 4:36 pm

    Can this be used with the M17, equipped with manual safety?. A lot of the responses on here are kinda confusing wether it works or not.

  34. scott - January 28, 2019 @ 7:42 am

    No, our trigger bar does not work with the thumb safety models.

  35. Scott - February 1, 2019 @ 11:48 pm

    Do the combo kits, specifically the 112-031 work in the .45acp compact and/or carry Fire Control Assemblies?
    Thanks for your time!

  36. scott - February 4, 2019 @ 12:07 pm

    Yes it does.

  37. paul - February 19, 2019 @ 11:53 am

    Not at this time.

  38. Robert N. - March 2, 2019 @ 9:57 pm

    Are you guys working on a trigger bar for the M17 Models with the thumb safety? I’ve recently purchased one and the trigger is unacceptable..

  39. paul - March 5, 2019 @ 11:12 am

    No, not at this time.

  40. Matt - March 25, 2019 @ 11:03 pm

    anything for the M17 manual safety ? I’m looking for some upgrades. any recommendations

  41. scott - March 26, 2019 @ 7:36 am

    We don’t offer a trigger bar, but we can offer you the Flat or Curved Advancing Triggers, either will reduce pull weight by roughly 2 lbs.

  42. Artur Gomes - March 29, 2019 @ 3:44 pm


    You deliver in Brazil?


  43. scott - March 29, 2019 @ 4:11 pm

    No, I’m sorry we do not. You can try ordering through Brownells.com

  44. James Mcmillan - April 15, 2019 @ 2:03 am

    Will these work with the .45acp versions??

  45. scott - April 15, 2019 @ 8:48 am

    Yes it will.

  46. Smark - May 27, 2019 @ 9:19 am

    From our website: “Not for use in Thumb Safety models of the P320.”
    Not at this time.
    No, our trigger bar does not work with the thumb safety models.
    No, not at this time.
    We don’t offer a trigger bar, but we can offer you the Flat or Curved Advancing Triggers, either will reduce pull weight by roughly 2 lbs.

    Any work for for the M17 manual safety yet?

  47. scott - May 28, 2019 @ 9:20 am

    Nothing to report yet. We have it on the list, but there are a lot of products ahead of it.

  48. Collin Thomas - July 10, 2019 @ 6:22 pm

    Just purchased a p320 full size with night sights. It does not have a safety. Are you saying this trigger only works on the x-series and m17?

  49. scott - July 11, 2019 @ 5:59 am

    Not at all, our trigger bar does not work on models “with” a thumb safety.
