Another Sig P320 Drop Test Failure? New Video Surfaces Of An Informal Test

When we learned that Dallas Police Department had removed the Sig Sauer P320 from the approved list due to a drop safety concern, the news had been accompanied by the video above that shows another P320 drop test failure. Unfortunately, the video was removed from YouTube before we were able to post it with the information that was gathered from both Sig and Dallas Police as to the reason behind the P320 being pulled off the street.

Thankfully someone emailed me a copy of the video that was removed from YouTube so that we can share it with you. I have uploaded it to my personal channel, but if anyone knows where the video originated from, please email me at so I can share their upload and get more information about the test.

I can’t speculate as to the condition of the pistol in the video other than it appears to be stock from the little we can see in the video. Now it is entirely possible that it has been modified internally but with the video Omaha Outdoors released today showing the P320 failing their own drop test it may well still bear stock internals.

It appears that a primed GECO 9mm case was placed into the chamber of the full-size P320 and then a magazine that has some number of rounds is inserted into the mag well, we do not know exactly how many were in the magazine though. The person conducting the test then holds the pistol at their eye height and drops it with the pistol pointed at the ground in a 45-degree direction. On what the video lists as the third drop, the trigger appears to move rearward and the pistol discharges.

Even though multiple sources have deemed the Sig Sauer P320 safe the existence of two separate videos showing the P320 filing drop tests calls that into question.There is always the possibility that both videos were faked in some manner, but my curiosity is at an all time high. I want to know what is going on just as much as all of you.

In a quest for answers, some P320 owners on social media have even taken the drop testing into their own hands and have shared their result.

TFB asks that you DO NOT attempt to perform your own drop testing in the interest of safety. 

These people that performed their own drop test are reporting that they have seen similar results to the Omaha Outdoors video with varying degrees of success. Some reporting a 100% failure rate with their pistols and others reporting it only occurring about half the time. Since the P320 trigger varies from gun to gun, it may well depend on your particular example as to if you will see a failure if the pistol is dropped in the manner outlined in the Omaha Outdoors. We can’t really say for certain at this point.

Does this mean that the P320 hasn’t been drop tested in this manner yet? Not as far as we can tell.

In a comment thread found in a Facebook group called Primary & Secondary about Dallas Police Department pulling the P320 from the approved list, the Omaha Outdoors video was posted and was discussed at length. In that conversation, one of the members of the group posted the testing protocol for the ANSI.SAAMI Z299.5 testing as well as the TOP protocol outlined by the U.S. Army Developmental Test Command. I have posted those below for you to take a closer look at or you can read the test protocols in their entirety at the links above.

We know that the P320 has been drop tested by a number of agencies and testing authorities such as SAAMI and the DoD. One could assume that the P320 has been subjected to both test protocols and has passed, so why are we seeing failures now? I wish that we could answer that but unfortunately, we just don’t know right now.

Am I ready to say that the P320 is unsafe? No. I will be unloading mine and putting it in the safe until I know more about what failures caused both the Omaha Outdoors pistols and the one in the video above to fire when dropped. The last thing I need is to have a P320 fall out of my briefcase and shoot my junk clean off.

As we said earlier today in the post about the P320 discharging when Omaha Outdoors dropped it, we will update you as soon as we learn more from Sig Sauer in regards to the P320.

    If this were a HiPoint or Taurus people would be demanding a recall ASAP. Sig fanboys flame on!

      • Dougscamo

        But not shot by dropping it….grabbing the trigger while drawing is another story….

        • Anonymoose

          I’d like to see some Glock drop tests with loaded chambers. Massachusetts won’t certify them for public sale, even with the crazy heavy triggers in them, so there must be some problem.

          • m-dasher

            MA doesnt certify A LOT of guns……its has no bearing on the actual safety of the firearm.

          • Giolli Joker

            We saw some Glock drop tests after Zev (AFAIK) touched up the trigger group… the owner almost got a new nostril thanks to that.
            Standard Glocks were ok.

          • Patrick R. – Senior Writer

            I just checked their approved firearms roster and see Gen 4 Glocks on it …. You sure they aren’t approved?


          • cwp

            It’s not that simple. In order to be sold in MA, a handgun has to be on the roster, AND it has to meet the “consumer protection” requirements in 940 CMR 16. If you meet only one or the other — no soup for you!

            I don’t remember what specifically it is in 940 CMR 16 that Glocks don’t have, but whatever it is, FFLs here do not sell them except to LEOs. You can still get them — I have a Gen4 G19 which I got new — but the process is so stupidly convoluted I’m actually embarrassed to describe it.

          • M1911

            The AG doesn’t like the Glock’s chamber-loaded indicator.

          • Matt from marxachusetts

            theres the approved roster list thats on the state website you saw, then there is th AGs list of handguns that have the blessing to be sold to civilians under the guise of public safety ect, that list is not public and with all the trouble the state has given to glock over the years glock gave up trying to appease the AG, not too long ago the p320 became mass compliant but it has a manual safety. walk into a gun store in mass and you will see its pretty pathetic,the selection of “compliant” handguns is pretty slim compared to most states. ohh and the same AG changed her interpretation of what a “copy cat” assault weapon is so now the featureless semi auto rifles that have been ok to sell in mass for over 20 years cannot be sold to civilians anymore.

          • JohnnyCuredents

            The Massachusetts AG is a left-wing lunatic and pervert who thinks old men in panties should be able to use women’s bathrooms (fairly recent news item; look it up). I wouldn’t trust her to mind my dog, let alone make any kind of judgement about firearms.

          • john huscio

            Massachusetts is a liberal shithole like california. They mandate the same kind of wacky stupidity when it comes to guns, id hardly use them as a baseline for firearm saftey

          • Echo5Charlie

            Back in the day the slide assembly would dislodge off the rails, but Glock has mostly fixed that I believe.

          • JohnnyCuredents

            And when was the last time you heard the phrase “Sig leg”? I never have, myself, but I’ve seen and heard “Glock leg” even from novice shooters. I guess in its way, that make’s Gaston’s product “famous.”

          • Dougscamo

            Somewhere on this blog in the past 24 hours, Sig leg has come up. Too many dropped Sig posts to keep up with to remember…

          • JohnnyCuredents

            Curious, isn’t it, how Sig beats the Austrian wunderpistole company and, suddenly, stories abound of faulty Sigs, stories no one ever heard before. Looks as though Democrats aren’t the only practitioners of fake news reportage in this world.

          • m-dasher

            well thats generally what happen when the army literally adopts a brand new pistol on the market.

            but Sig is issuing a voluntary recall for the pistols…….so there must be Truth to the stories………i hardly doubt Glock is on some major smear campaign.

          • M1911

            You don’t understand the process in MA. This is a political issue, not a technical one.

      • ozzallos .

        I just can’t stop watching him spontaneously combust.

    • JohnnyCuredents

      It it were either of those brands, no on would even notice. If there is a problem, it’s news simply because many of us are well acquainted with the quality of Sigs from our personal experience. We don’t have a peculiar ax to grind as some owners of a European brand clearly do.

    • A.WChuck

      I like Sig, but this needs a recall. Another video on Youtube shows repeated failures with a brand new p320. The failure seems to easily duplicated.

  • George

    Trigger should have gone the other way if it’s trigger inertia…

    How heavy is the transfer bar or equivalent? Not familiar with 320 internal components…

    • ColonelColt

      The fire control group design on the P320 is honestly really fiddly. A lot of it looks like it was designed to get around other people’s patents and they located the trigger-deactivated striker block IN the striker housing… Which has a little spring that’s been breaking or flying off on people. So Sig told them to stop taking their slide apart period.

    • Joel

      Root cause appears not yet definitively determined.

  • PersonCommenting

    Patrick have you tested yours yet?

    • Patrick R. – Senior Writer

      Not yet. I have plans to test it depending on I learn in a conversation with someone who knows these guns inside and out later this week. Sadly it wont be until next week that I can get to it due to travel arrangements.

      • Dan

        Oh you haven’t tested yours? Hmm weird. Because in the Dallas PD recall post you said this.

        “Patrick R. – Senior Writer  Sliced Veggie5 days ago

        I spent about an hour doing that earlier, couldn’t get the primed case to fire”

        So….Did you forget you spent an hour dropping your gun?

        • Patrick R. – Senior Writer

          I spent some time dropping it in the garage, yes. I haven’t spent time to set up a test where I can provide data and video to back up that data. A proper test isn’t the same thing as me dropping it on a garage floor for an hour trying to figure out what might have happened.

          You sure do spend a lot of time following me around. Kinda a lame hobby isn’t it?

          • Steven Calvaresi

            I did the same thing with my Glock 17C (kitted out with ALG 6sm mount, optic, light, suppressor, and ZEV fulcrum trigger) after I heard about the glock issue with ZEV triggers. (yes, I’m not right in the head, but my guns aren’t safe queens either). Even with the extra weight, ZEV trigger, and hitting a hard (not rubber) surface, I couldn’t get it to go off. #teamglock all the way

  • Anonymoose

    I have to wonder if they’ve done any drop testing with the thumb safety models that were adopted as the XM17 and XM18, but I’m not sure SIG is even selling those to anyone besides the military at the moment. If the thumb safety blocks the sear, then that probably gave them a pass in military testing. Also, we have to be honest and recognize that all of Glock’s “dropped out of a plane/helicopter” tests were only to show that the gun wouldn’t break after falling that far, not for drop safety, and were always done with an unloaded chamber. Even Larry Vickers put his G17 in Condition 3 before tossing it out of an aircraft, and advocated that military users carry in Condition 3, which I’m sure is the norm for British, Austrian, and other countries’ armed forces.

    • The ones with safties they say will never be sold to the public.

    • CapeMorgan

      According to the article, the drop test protocol does indicate that the safety needs to be on…and use a rubber mat , so it would appear that the XM models passed. Although, the ‘rubber mat surface’ part of the test seems less than a real world test.

      • neoritter

        b part 3 – Drop the weapons on a clean, level, concrete surface.

        • CapeMorgan

          So it passed the ANSI test without the safety on, but to pass the Army test it needs the safety engaged?.

          • neoritter

            Not sure, the ANSI test doesn’t say whether the safety is in the safe position or not. The Army test indicates safety in the safe position and it drops the gun on concrete.

            Here’s the ANSI stuff above what’s given in the article:
            “5.1. Applies to: Rifles, Shotguns and Handguns 5.1.1. This test simulates the abusive dropping of the firearm. 5.1.2. With the firearm in the “Safe Carrying” condition, the firearm shall be capable of passing the below test criteria for drop testing from a height of four (4) feet (1.22 m) onto a 85±5 Durometer (Shore A) rubber mat, one (1) inch thick (2.54 cm), backed by concrete. The mat and concrete shall be large enough so that when the gun is dropped it will fall and come to rest without interference within the perimeter of the mat. The drop height shall be measured from the surface of the rubber mat to the center of gravity of the firearm. The center of gravity shall be determined to an accuracy of ± one (1) inch (2.54 cm) by any recognized method for finding the center of gravity of an irregular shaped object. The firearm shall be re-cocked and reset in the “Safe Carrying” condition after each drop or a separate firearm may be used for each drop. As an alternative to free dropping, other methods may be substituted if they provide equivalent impact characteristics. 5.2. Criterion – The firearm shall not fire a chambered empty primed case of its designated cartridge when tested in accordance with this procedure. In a multi-chambered gun the primed case(s) shall be inserted in the chamber(s) directly in front of the firing pin(s). Parts breakage or other damage resulting from drop testing does not constitute failure as long as the empty primed case does not fire and the firearm can be unloaded safely after each drop. ”

            “Safe Carrying” condition is the wording they use. I guess that means safety engaged?

    • Echo5Charlie

      If the M17 passes the drop test with the safety on – great. If it fails with the safety off, well, that’s an issue.

      Sidenote – a rubber mat is a bit of BS. I wouldn’t be surprised if this is how the P320 limped through the half-assed testing by Big Army.

      • neoritter

        The rubber mat from the ANSI guidelines appears to be a durometer.

      • David Rice

        An 85-90 durometer reading isn’t particularly soft: think of a 1-in. thick mat made of a cured two-part epoxy resin resting on concrete.

  • Haulin’ Oats

    In the Omaha Outdoors video he tried many brands of live ammo. How are they doing these drop tests standing next to the gun with live ammo without shooting themselves?

    • Orion Quach

      Because the chambered round is a blank if you would read lol

      • Patrick R. – Senior Writer

        If YOU would read you would have known that they used a primed case, not a blank.

        • Giolli Joker

          That is technically different but functionally the same: no bullet, no danger.

          • Patrick R. – Senior Writer

            There is far more danger with a blank than many people think. Personally, I wouldn’t conduct a drop test with a blank, only a primed case.

          • MB

            Blanks are dangerous if you hold a 44 Magnum loaded with blanks to your temple and pull the trigger like actor John Eric Hexum did 30+ years ago, blowing a 1/2 piece of his skull through his brain and out the other side. Other than that blanks are fairly safe….

          • Giolli Joker

            Blanks at very short distance may indeed be dangerous (a bored actor managed to get himself killed with one).
            At that distance I would not want to forget my safety glasses, but other than that I don’t see that much of a risk.
            A primed case may be cheaper as well.

          • Patrick R. – Senior Writer

            Cheaper and more readily available. They are a lot less loud too.

        • Orion Quach

          What’s the diffence between a primed case and a blank?

          Edit : I see the second comment now

    • Patrick R. – Senior Writer

      Primed case. They pull the bullet and powder and use just the primed case.

      • SGT Fish

        had a fellow soldier in Afghanistan almost lose his eye from just a primed case. not very safe either! an inch higher and he would have more than a scar on his cheek

    A Stamford police officer has sued gunmaker Sig Sauer over injuries he suffered when his holstered P320 pistol discharged and hit him in the leg after he dropped it in a parking lot.

    According to the complaint filed Aug. 4 in the U.S. District Court for the District of Connecticut, officer Vincent Sheperis dropped his holstered department-issued handgun while loading equipment into the back of his car in January. The gun fired when it hit the pavement, and the bullet entered beneath his left knee and lodged to the side “with the round protruding from his leg.”

    Sheperis, a 34-year-old member of the department’s Special Response Team, underwent multiple surgeries and is back on light duty, although more surgeries may be required, according to his attorney, Jeffrey Bagnell of Westport.

    Sheperis is seeking at least $6 million in punitive and compensatory damages, and is demanding Sig Sauer recall the pistol or include a warning that the gun is not “drop safe” when a round is chambered.

    “For it to just go off—it’s kind of horrifying, really,” Bagnell said.

    The Stamford Police Department said it’s shelved all P320s it issued to its officers because of the incident.

    The suit comes amid ongoing reports that the P320 is prone to accidental discharge when dropped. The Dallas Police Department in Texas suspended use of the P320 due to safety concerns, according to a spokeswoman there.

    “We have not currently had any issues with the Sig Sauer P320 handgun,” according to a statement provided by public information officer Melinda Gutierrez. “The use of the Sig Sauer P320 handgun has been temporarily suspended due to safety precautions. The departmental Firearms Training Center staff is currently working with Sig Sauer to ensure the safety precautions are addressed.”

    Sheperis’ complaint includes a litany of incidents in which law enforcement officers’ Sig Sauer handguns allegedly went off without the trigger being pulled when dropped or being handled.

    There was no immediate response to a message left for Sig Sauer’s media representative or the attorney handling the matter for the gunmaker, Robert Joyce of Littleton Joyce Ughetta Park & Kelly in Purchase, New York.

    In an Aug. 4 statement, Sig Sauer said it has “full confidence in the reliability, durability and safety of its striker-fired handgun platform. There have been 0 reported drop-related P320 incidents in the U.S. commercial market, with hundreds of thousands of guns delivered to date.”

    “All Sig Sauer pistols incorporate effective mechanical safeties to ensure they only fire when the trigger is pressed,” the statement said. “However, like any mechanical device, exposure to acute conditions (e.g. shock, vibration, heavy or repeated drops) may have a negative effect on these safety mechanisms and cause them to not work as designed.”

    Sheperis’ complaint includes counts for violation of the Connecticut Products Liability Act and Unfair Trade Practice Act, and for negligent infliction of emotional distress.

    The complaint notes Sig Sauer’s marketing materials say its safety mechanism prevents the gun from discharging “unless the trigger is pulled.”

    But the manual states the P320 “may fire without the trigger being pulled if the chamber is not empty. It is, however, standard operating procedure for all U.S. law enforcement agencies, local police departments, and the military to carry pistols with a chambered round,” the complaint adds.

    Bagnell said there were pre-suit discussions regarding a settlement, “but they did not result in a resolution.”

    This is looking worse and worse for Sig.

    • venku

      “or include a warning that the gun is not “drop safe” when a round is chambered.”

      Job done for Sig then, because as I recall there actually was a warning in the manual.

    Comments on this topic continue to be riddled with “but what about Glock” questions. One of certainties Glock reliability and durability has proven over the last 3 decades is that a Glock pistol will not fire if dropped, not gonna happen.

    It would be interesting to know how many Glock haters have scrounged up a test gun since this P320 scandal broke last week and have been frantically drop testing the $#it out of some Glock in attempt to replicate the Sig drop test failure with a Glock only to discover that they just can’t make it happen. LOL!

    • Dougscamo

  • flyingburgers

    Crappy standard + company that tests only to standard and you get a multi-million dollar recall.

    If they were in aerospace, it would read something like: “Drop the weapon such that it impacts the test surface at the most critical orientation. The most critical orientation is the orientation such that the weapon is most likely to discharge due to impact and shall be shown by engineering analysis.” Then attach 20 pages of kinematic analysis covering each failure mechanism and what magnitude of impact it can withstand.

    “Even though multiple sources have deemed the Sig Sauer P320 safe the existence of two separate videos showing the P320 filing drop tests calls that into question”

    Does it? We have a sample size of two, and I can’t tell if this example is an exact replication of the first “test” or not.

    What this does call into question is the public’s lack of knowledge of statistics and research methodology. There is a lot more to proving or disproving a hypothesis than Youtube videos. The SIGs may be rattling death machines, but until someone pulls a significant sample size and applies some rigorous, valid and repeatable testing I decline to flip out.

    Then again, I drove a Corvair without killing myself and a Ford Crown Vic Police interceptor without bursting into flames, so maybe I’m just an optimist.

    • Echo5Charlie

      Supposedly failed the FBI drop test and I have a source that claims the Army drop test did not fare….well..for SIG.

      There is no trigger safety on the P320 and it has a very light and short trigger pull. Taurus has the same issue with the original Millennium series.

  • Rnasser Rnasser

    Somebody at the US Army must be cranky over all those millions and months expended by experts to pick a pistol that is not drop safe…

  • Echo5Charlie

    The P320 is the firearm equivelant to the adoption of UCP by the US Army.

    7 years from now Glock pistols will be issued to forward units and shortly after that all M17/M18 pistols will be replaced by Glocks.

    Also, the drop test failure is actually a feature, as evidenced by this still from True Lies.

    • Steven Calvaresi

      Is Glock the multicam of pistols? lol

      • Echo5Charlie

        Not necessarily, but the M17/M18 (as of right now) is the UCP of pistols.

    • Patrick R. – Senior Writer

      We will be recreating the test soon. Several people have proved that the P320 is not drop safe, there really isn’t a question now.

    • Steven Calvaresi

    “the trigger appears to move rearward and the pistol discharges”
    The video shows the pistol discharging (bang and later flash) before the trigger moves. Please explain that sequence of events.

    • Dean Fellabaum

      You must have watched a different video than the rest of us, Brother…


    I guess the government probably should have completed the testing before choosing the P320. What a joke.

    I thought it had to be dropped in a very specific way on the back of the gun to get the inertia to transfer to the trigger. Cleary any angle drop will do.

  • A.WChuck

    TTAG has a video up of another test of a brand new P320 and it too fires when dropped. That’s enough for me to believe there is a design flaw that must be fixed. It seems easily repeatable. On Youtube under Jeremy S. channel if you want to avoid TTAG like I do.

  • BeGe1

    Crap…that’s not even the same position as the ND failure from the last video.

    This is getting REALLY bad.

  • Seth Hill

    “On what the video lists as the third drop, the trigger appears to move rearward and the pistol discharges.”

    Watch it again at about the 39 second mark, it fires BEFORE the trigger moves.

  • Did anyone else notice that there was no recoil from the gun whatsoever? And who, in their right mind would drop a loaded gun (standing right directly behind the gun,) with their bare hands and NOTHING to protect them in case of a mishap? I call BS on this video, they have to be using blanks! If they were dishonest enough about the ammo supposedly used, then they were probably dishonest from the start. This is fake news!

    • NDS

      It’s an empty, primed casing. Even a blank would be dangerous.

      • But would just a primer, even a magnum primer, make that much flame out the muzzle? I am going to have to try it with one of my casings! I’ll try to let you know my findings. Thanks for the idea!

        • M1911

          Yes, it would.

  • Lawren Downing

    What’s really funny about this whole thing is none of this “Testing” would have happened if not for the spreading of a false rumor regarding Dallas PD. It was that lie that started the whole drop test debacle. On top of that it took individuals several drops from every conceivable angle and height to find just the right angle and just the right height to make the gun go off. That doesn’t change the fact that there is a flaw and Sig will have to address it, but the consequences for which this whole thing came about just amaze me. This gun could have gone on for years in service without a single issue from being dropped, but because of all the hate Sig has gotten from competitors about the DOD contract it’s enemy #1 by those who feel their personal choice should be the next military sidearm.

    I have personally replaced my stock trigger with a lighter flat trigger so I have no intentions of getting rid of my P320. Even if it still had the stock trigger I would be carrying it daily. Sig will do what every other manufacturer has done when a flaw is found. They will quietly throw updated parts at it until the issue is resolved ie- Gen4 Glocks recoil springs and extractors. I also don’t see the military suddenly swapping to the Glock. The decision has been made and the DOD contract moves forward. So I guess Glock fanboys enjoy your early Christmas present and let the memes flow, but in 30 days it will be in the past and nobody will care.

    All this and I was hoping to get a good price for my SIG 290 RS on the coat tails of the M17 contract. At least the 290 RS is double action only hammer fired.

    It is the same issue as dropping the gun backwards – the trigger moves under inertia and the gun fires. If Sig fixes that trigger issue with a trigger-in-a-trigger Glock style or perhaps a very light weight trigger, this and the other problem will be fixed.
