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.

    As far as we know at this point, BUT we have not been able to test all the newer variants.

    Good evening,
    The performance enhancements of your triggers and trigger bar are well documented with the P320 / X5. Do any of your triggers or the trigger bar offer any performance upgrades to the P320 Legion? My goal is to reduce travel and trigger rest while maintaining pull weight from the stock P320 X5 legion.

    Thank you

  3. paul - September 3, 2019 @ 1:39 pm

    We have not tested the P320 Legion with our trigger bar so we cannot confirm how it will perform.

  4. Dan Piatt - September 14, 2019 @ 3:13 pm

    Do you make a trigger upgrade for a SIG 320 M17 with manual safety?

  5. paul - September 16, 2019 @ 9:51 am

    No we do not have a kit with trigger bar that will function properly in the thumb safety models, like the M17. Our trigger bodies alone will work in the thumb safety models.

  6. David Flanders - September 20, 2019 @ 3:01 pm

    Do you have a trigger bar for the x5 legion. I am looking to reduce take up and reset and possibly a little lighter pull.

  7. paul - September 20, 2019 @ 3:06 pm

    Not at the present. We are looking at the new pistol and trying to confirm proper fit and function with our kit.

    Hi, ive been curious since the release of the trigger bar. I have an black xfive, And i like the style of the trigger and the pull weight is great. But the pre travel isnt great and the reset if awful. If i only upgarde the trigger bar what will happen. Will it all so push the trigger forward more? Does it shorten the reset? Lastly willbit still break at 90°? Thank you!

  9. Justin - September 28, 2019 @ 2:26 am

    Has this been tested for compatibility on the X-Carry?

  10. scott - September 30, 2019 @ 7:14 am

    Our trigger bar moves the break point further forward. If you install our bar with the factory trigger, you will wind up with a heavier pull but a super short length of pull. This is why we strongly recommend one of our Advancing triggers be paired with the trigger bar.

    Yes, the reset is shorter with our trigger bar due to our over travel being shorter.

    We setup the triggers to break as close to 90 deg as possible, but over travel to the opposite angle as the trigger sits at it’s rest position.

  11. scott - September 30, 2019 @ 7:15 am

    Yes and as far as we’ve tested, all works as intended.

    The stock trigger pull on my 2018 Sig p320 x5 measures at 4.5 pounds. I like the design of my current trigger so which kit will improve the trigger pull and keep the same configuration that I have now. Please advise. Thanks

    Do you offer a trigger bar and trigger for non-upgraded Sig 320’s?

  15. scott - November 18, 2019 @ 5:39 am

    We do support the non-updated P320 platform for liability reasons. Sorry.

  16. scott - November 18, 2019 @ 5:42 am

    Which X5 do you have? If you have the Legion, we have something in the works.

    If you’re running a Non-Legion, one of our Advancing triggers would be your best bet if you want the pull weight lower.

    If you want to reduce the overall trigger movement to fire(pull length), our trigger bar will reduce the trigger pull by roughly 35% of it’s overall distance, but it will up the pull weight by nearly 1 lb.

    Just had an Apex 112-032 trigger kit installed in my P320 Compact and I noticed that the over travel stop and over travel stop spring were installed in reverse. Does that make any difference which comes first ?

  18. scott - November 22, 2019 @ 6:49 am

    The only thing it could cause is the spring to rub against the disassembly lever and potentially mess up the spring, but it shouldn’t be an issue.
