New Apex Advanced Trigger For P320 Reduces Trigger Pull By 2 Pounds

The new Apex advanced trigger promises to drop approximately two pounds from the factory trigger pull with only a trigger replacement. We previously tested the flat trigger on my P320 Compact and found it to be pretty good with the exception fo the finish used on the trigger itself. It was a bit on the slick side for serious use in hot conditions with a rather slippery trigger face.

The new trigger is offered in both flat and curved flavors, both versions offering the same 2-pound reduction in pull weight. The trigger is a direct drop-in replacement for the factory trigger and required no tools to install. Apex says that the new trigger doesn’t change anything in regards to the drop safety and will work with any caliber or size of P320.

I must admit I would love a chance to check the new trigger out since I liked the original so much. This new advanced version looks like it could really liven up my Sig P320.

Features and Specifications:
– Reduces trigger pull weight by approximately 2 lbs.
– Direct drop-in replacement of factory trigger
– Maintains factory drop safety values
– Works with Sig Sauer P320 model pistols in 9mm, .357SIG, .40S&W and .45ACP
– Flat or Curved option
– Easy, no tool installation
– Apex Part #: 112-021 (Flat), 112-022 (Curved)
– MSRP: $49.95

The new trigger will ship to dealers and distributors on March 28 and will carry an MSRP of $49.95. You can learn more about the trigger over at Apex’s website.

    And INSTANTLY voids all warranties and completely relieves Sig of ANY liability connected with the pistol because when you alter any factory new firearm you assume all liability.

      My $450 pistol is no longer covered under warranty. What will I do!?

          You could only possibly be sued if you had a negligent discharge and hurt someone, not because you used it defensively.

          • iksnilol

            You were modifying your gun to kill more effectively. You were basically looking for someone to kill.

          • David H

            So any new sights and I would get sued into oblivion. You are incredibly wrong my friend. You modify your gun so you can shoot more accurately.

          • iksnilol

            Sweet Jesus, I was poking fun at Massad Ayoob saying everything will be used against you in prosecution.

    • Will

      Good point, nobody is going to want to mod their polymer, striker-fired guns. What was Apex thinking?

    • Audie Bakerson

      That would kinda defeat the point of the P320 if true…

    • DonDrapersAcidTrip

      “when you alter any factory new firearm you assume all liability.”

      thanks dad

    • M1911

      I’ve modified almost all of my handguns in one way or another — trigger jobs, different sites, connectors, etc.

      As for liability, I can’t see any likely situation in which the manufacturer would have liability that would be of much importance. The situations where liability would be important aren’t ones where the manufacturer would be at fault.

      P320 X6! P320 Viking! I’ll save my euros!

      • AFAIK all P320 production is state side. So the crazy German X guns likely won’t be happening with the 320.

        • K-Gunner

          They already announced and showed a P320 X Five at SHOT 2017. Sure it’s not the same thing as the P226 X Six but Sig is trying to give the P320 that treatment.

          • When I said crazy German X guns I figured everyone realized I was talking about the Viking and the other absurd European collectable guns that are popular over there.

          • K-Gunner

            Yeah there are some crazy versions that nobody wants here. I would love an X6 though. A Sig rep at SHOT told me that they’re going to make the X6 again but Stateside.

        • Anonymoose

          Don’t be a drag. 🙁

    • Dw

      So wrong and yet somuch yes

  • Just say’n

    I really like the P320 trigger just the way it is. SIG did a great job, no need for “improvement” in this case. And why would anyone want to significantly reduce the factory-adequate trigger pull on a striker-fired pistol anyway? Sounds like a recipe for disaster.

    • Jack

      Nobody’s ever done anything else to any other perfectly serviceable firearm that was bone stock from the factory. It’s crazy to think people might want to mod their stock gun. Just saying.

    • Stuki Moi

      In low recoiling guns, the greatest practical shooters on the planet, generally see measurable benefits in split times at a given accuracy from lighter, shorter triggers. For the rest of us, dorking around with “problems” as already conclusively “solved” as the striker fire trigger one, is just falling prey to apex (quite literally in this case 🙂 ) fallacy.

    • Dr. Longfellow Buchenrad

      Apart from competition use I would agree about the weight reduction, but while I do find the factory Sig trigger to be adequate, even nice sometimes, generally speaking, improvement is always better when it doesnt compromise safety. This seems like a nice mod if youre building a race gun, but Im sure a few will still find their way on to defensive pistols…

    • John

      Apex became famous for their Smith and Wesson M&P triggers, which reportedly turned the gun from an ok pistol into a competition-worthy defense pistol.

      So when Apex releases a trigger for a gun, people pay attention.

      • Nicks87

        Yes, almost a necessary item on the M&P but the 320 has a way better factory trigger than the Smith. But it’s your money.

  • Nicks87

    Do we really need a 3lbs trigger pull on a defensive pistol? Competitions? Sure. But probably not on something you carry everyday.

    • Joe

      The P320 feels lighter than you think (I think due to the trigger shape), but most are in the 7-8 lb range.

      • Nicks87

        You might be right the few that Ive picked up at gun stores felt like 5lbs or so.

        • nova3930

          I finally got a trigger pull guage and measured mine. It was a hair over 7lbs on my my compact and FS….

    • Stuki Moi

      One of the most strongly held superstitions of Gun Culture 2.0 is that lighter is always better for triggers. Without reservation, since Tactical People yell “Keep your finger out of the trigger guard until you’re on target!!”

      It’s up there with “The shortest reset is always best,” and “all terminal ballistic properties of a round of ammo, can be 100% determined by measuring resting diameter and penetration depth after its shot into a block of gelatin.”

      • Your rights lighter =/= better, but a better trigger pull is better. I would rather have a good clean breaking 6lb trigger pull than a crappy 4.5lb trigger pull.

  • b0x3r0ck

    And it begins now that the p320 is the new army of choice handgun the aftermarket support starts to pickup. In a few more years we all going to be like “Glock who why would I buy that”.

    • Bigbigpoopi

      Not until they make 30+ round mags that are $20-30

      • Lee M Attinger

        lol!!! 30+ round mags.

    • Stuki Moi

      Space efficiency will still remain king for many civilians. To a much greater extent than even for contemporary soldiers.

      • The size differences are minimal, and for a better trigger and ergonomics it is worth it.

        • DonDrapersAcidTrip

          A glock feels fine and doesn’t have a two foot tall slide

          • 2 foot high slide? Seriously, other than Glock virtually all the striker guns have similar slide profiles and bore axis. And again it is like a fraction of an inch.

    • No one

      So did everyone buy Beretta 92s and make the P226 go extinct after it smashed it in army trials by this logic?

  • Bradley

    Good trigger pull sucks. Everyone knows that.

  • Geoff Timm

    Now let me get this straight, you buy a SIG 320 for the trigger, then try to make it lighter? Geoff Who notes there are Duty triggers and target triggers.

    • M1911

      I bought 1911s for their trigger pull. And I had a trigger job performed on each and every one. For some, that just involved tuning of the existing parts. For others, that involved replacing parts – trigger, connector, hammer, etc.

      Some of those guns were primarily competition guns. Some were primarily for carry.
