EFFECT OF ADJUSTABLE TRIGGERS ON P320 SAFETY

  • Опубліковано 18 сер 2024
  • In this video I study, test and explain how adjustable triggers affect the internal striker safety on the P320 and can (if tuned incorrectly), unintentionally cause some of the safety to be removed without the operators knowledge. I do this by testing the movement of the striker relative to the trigger's travel and then documenting the distance the safety travels, later showing subscribers in detail how much safety was removed.

    Once again, great content!! I’ve been telling people all along that removing the pretravel deletes the striker safety and this video articulates that concern perfectly. There is a simple fix for folks who want to eliminate pretravel and retain the striker safety feature…. The Apex forward set trigger bar. I believe you did a video on that a year ago. You should do a video with that trigger bar and your 3d printed slide to demonstrate how pretravel is eliminated but safety is retained.

    Thank so much for these videos. I compete with P320’s and have 10’s of thousands of completely reliable rounds thru my un- modified FCU’s. I asked my gunsmith , who also competes with a Max , if I should investigate trigger mods and he simply told me not to bother . Once broken in , my P320 Max triggers have a crisp break at 3.5 lbs .The difference is all in the striker assembly . I can take a well used striker , put it in a slide with an unused FCU that is “mushy” with a new striker and it will be then be crisp. I’m assuming that’s just due to the polishing thru use of the sear and trigger bar interface and spring wear. Therefore , as anyone who wants to be proficient with a firearm should be firing a lot of rounds , the triggers will get to where you need them to be . Speed in pistol matches is all in the dead time between shooting and scoring splits are not required to be nor should be blazing fast. I feel this is a safe stock platform if you simply don’t pull the trigger when not intended .

    To fix this issue , just remove some material on the bottom of the striker safety arm so when the trigger is adjusted it does not lift the arm out of the way until the trigger is fully depressed .

    Interestingly, aftermarket Glock triggers have similar effects once you start eliminating takeup. The relative starting position of the trigger at rest is what affects the trigger bar's position on the firing pin safety and in the drop safe ledge. Once you continue adding take up reduction to a certain point, you are able to move the trigger bar past the drop safe ledge while the trigger is at rest, causing an unsafe condition. I agree completely this should never be done on a carry gun.
    Interestingly, I've compared a stock trigger and Overwatch precision trigger bar position and they are the same. I generally recommend those as suitable replacements as all safeties are functional.
    Anyhow, merry Christmas from my family to yours Edmund! Cheers!

    Another amazingly informative effort, and which I believe could have significant consequences for the recurring claims that P320 pistols sometimes discharge without the trigger’s being pulled. Whenever I’ve participated in discussions about such claims I immediately point out that the safety lock prevents striker protrusion through the breech face unless the trigger is pulled to raise the safety lock from its blocking position. If, however, tuning the trigger moves the safety lock out of its normal blocking position, that significantly compromises the safety design of the pistol.
    Although you clearly state that you haven’t determined whether improper tuning of the adjustable trigger can reduce the sear engagement in addition to affecting the position of the safety lock, that certainly seems likely. Without the safety lock’s protection, anything such as the right sort of impact that caused the striker to be disengaged from the sear would cause an unintended discharge. I can now only wonder how many of the supposed self-discharge incidents have involved adjustable triggers.

  • @ronmartblog

    Thanks for another amazing video Edmund!
    Our range had its first incident in 91 years where someone shot themselves when holstering. Sadly it was with a P320 and was due to his shirt getting caught up in the trigger well which created resistance which allegedly led to him using a more forceful push which discharged the firearm into his leg.
    Given the fact it was a competition, I wondered if an adjustable trigger may have exacerbated the problem.
    In this case, it seems like the default give would have been helpful but it’s hard to say it would have been enough to prevent this unfortunate event.
    I wonder how many other cases of P320 NDs are induced this way via using incorrect holsters, garments coming into play and adjustments to the pre-travel.

    A bit late to the party, but this could be resolved with modified geometry of the trigger bar where it engages the safety release. Increasing the gap by removing a small amount of material from that specific section of the trigger bar would delay the raising of the safety tab to later in the pull, meaning the safety tab will stay fully engaged until the trigger bar is closer to engaging the sear release. The exact amount of material removal/geometry change is up to the people who are looking for this kind of adjustment, but that's the basic solution. Sig erred on the side of ensuring the safety is well clear of the striker by the time the sear disengages, ensuring that the striker does its thing if the trigger is being actuated at all (e.g. you've got your finger on there).
    Or a fully custom trigger bar. Either way. The ramp geometry for the internal safety, in relation to the sear release geometry, is what matters.

  • @ShotPlacement
    @ShotPlacement 5 місяців тому

    Excellent video, and I can't thank you enough for putting this out there.
    One suggestion to help give people a real world example of the danger would be to overtune the travel, assemble the gun, chamber a unloaded yet primed casing, and then drop the gun muzzle first onto concrete from a few feet off the ground. Would make for a powerful visual for people to understand the danger.
    Very important thing to understand not only for someone carrying a gun for CCW or duty but also for competitive shooters to understand. People drop loaded guns on occasion.

    • @SIGMECHANICS
      @SIGMECHANICS  5 місяців тому +1

      The only issue I’d have with that is it does not go off during that test, it might give a false sense of security that 50% of the safety is “good enough”. I 100% agree with you in how the chance of dropping a gun exponentially increases in stressful situations. My personal opinion is that any loss of safety is unacceptable and due to how amazing the trigger is BECAUSE of the shorter travel in the P320, I’d warn anyone to modify it enough to alter any of it.

    Great video topic. Cant wait to watch. I think that if a man owns a gun, he has the right and Duty to know precisely how that gun functions and to KNOW that it is in safe, working condition (which he cannot do without understanding how it works). I think I already know the answer to the initial question, but I'd still really like to see just exactly how much it takes to disengage that safety and also to cause the sear to become unstable/unsafe. Reading up on the specifics of the lawsuits was good research on the mechanics of these guns and was good evidence on why the owners/operators were at fault for their "accidental discharges" that they tried to blame on the gun and its design.

    Well done on the 3D shell to visualize operation. Cutaways are so cool.
    That said, it's pretty clear that the safety of the 320 is okay at best when not modified, but because it lacks safeties inherent to other guns, even innocuous tweaks like pre-travel make the 320 even less safe. That's concerning.
    I fully believe what SIG said about the recent police video and accidental discharge - something has to be pressing the trigger to make it go off. That said, your videos have made it very clear not much pressure is needed to disengage the internal safeties. Competition guns are even higher risk.
    To my understanding, the manual safety model of the FCU, and Agency's trigger dingus are the only two remedies to prevent the current form of accidental, or uncommanded discharges. What're your thoughts? I'd love to hear if you know of other alternatives or options for those that like shooting 320s, but prefer them to stay under control. 😏

      In stressful situations like defence or competition it will probably come down to the proficiency of the operator. Bad habits and inexperience could definitely compound problems that lead to ADs. However, even at 50% loss, you still do have safety left to go… not ideal but at least it’s present.
      The trigger results however are also VERY impressive, I would not be able to rate it being how subjective that is, but when I look at the data from the trigger video I made, you can clearly see where the adjustable triggers are better.

    Greyguns and Sig Armorer have modified sears, how does that effect safety? Greyguns website says with modified sear, it should only be used on range or in competition. Sounds like safety may be affected? This video was great. I want to get rid of some of the creep in my trigger but don't want to mess with safety mechanisms. Apex trigger bar removes .036" of travel according to your video. Maybe that should be my route.

    • @SIGMECHANICS
      @SIGMECHANICS  6 місяців тому +1

      The modified sears help remove creep (or the feeling of it), it essentially has them shave off a bit of material at the sear’s ledge. In the grand scheme of things, it’s not enough to make it fail, but liability probably dictates the statement about “competition use only”.
      So long as your not tuning the trigger to remove take up (like with the adjustable trigger) you would technically be fine. Apex being a great option.

    I've been watching your content after hearing about the Sig ruling against out of Mass. It seems like there are a lot of internal safeties on these, despite the court ruling that the design is inherently dangerous owing to a lack of external safety, like the trigger blade safety of a Glock. I've also heard a bit about some people who have had seemingly hands-free NDs where SIG said it was a defective Firing pin return spring. Seems like the return spring wouldn't be able to push the striker thru the striker safety if it weren't disengaged though. maybe I'm wrong though.

    • @SIGMECHANICS
      @SIGMECHANICS  Місяць тому +1

      I believe a lot of the data out there is not coming from people reading from court documents. For the most part I believe it’s just “bad news is more entertaining than good” and so that is what people promote on things like UA-cam as it gets more clicks.
      The truth is as unfortunate as it may be, these triggers are being pulled sufficiently to disengage safety, and even more so to the point where the sear drops enough to disengage the striker. As far as the return spring goes, it’s funny you mentioned that because that particular spring is something that Sig had discontinued in around 2020-ish due to the fact that it is redundant. The striker will reset itself after a discharge, and once the slide makes the return lock position. It will not have any effect on causing a negligent discharge.
      Most of what you see on this channel allows people to visually understand the internal components and their mechanical interactions. Beyond my own testing and purely on the engineering alone, I do not think any of those discharges occurred without a trigger pull. Even if the operator did not touch the trigger, something else had replicated a trigger pull, either an article of clothing or an accidental touch of the trigger to a holster or other object.
      That being said, you should only use and carry what you feel comfortable with, as I don’t intend to particularly sway viewers one way or another, only provide the data to help them come up with an opinion of their own.

    So, couldnt this problem be remedied by removing material from the safety lever where it touches the lock lever? In doing so, it allows the safety lever to rest low enough that there is no safety delete while allowing the trigger bar to come far enough forward to touch the sear?

    • @SIGMECHANICS

      The key would be to keep the radius very consistent to what’s existing. Theoretically though, yes!

    Amazing video as always! One question: on a factory non-adjustable trigger, when we take up the slack to the “wall” is the striker safety fully disengaged at that point?

    • @SIGMECHANICS
      @SIGMECHANICS  7 місяців тому +1

      Thank you! No, the slack at that point would remove the small gap between the safety lever and striker lock lever. I made a video where I tested every single P320 trigger ever made and in that video you can see a graph for each trigger that will show you the play of the trigger. Here’s the link: AN ANALYSIS OF EVERY P320 TRIGGER...EVER

    Theoretically, what if the trigger bar that engages the striker safety was thinner so it had to travel more distance to disengage the safety? Then you could adjust the take up out, and only then would the bar be making contact with the safety.

    I just have to say that when looking at all the mechanical parts in the firing mechanism of the P320, and then looking at the mechanism parts of a 1911, that the Sig appears to be made of lightly constructed parts that I DO NOT expect to have the operational service life of 1911 parts, which are comparatively all larger, more robust, and part of a simpler, tougher mechanism. I have an M17 and it's a good gun...but all of my 1911s will outlast it, even my oldest which is already 106 years old and still functions like new. The firing pin assembly in the 320 looks comically small and fragile.

  • @slowslowslowrobot

    Is it possible for a normal user without the 3d printed slide rig you made to adjust the pretravel to the point that it just barely makes initial contact with the lock lever? I.e., the maximum adjustment point with 0% safety loss if I understand your video correctly? Would you consider making your model of the slide rig available? Thanks!

  • @jbays6125
    @jbays6125 7 місяців тому

    Merry Christmas! Thanks for a great video. So I was wondering if they could just make the sticker safety with a bigger ledge since there seems to plenty of room for movement you would not lose the safety factor or would that negate the enhanced trigger ? Like the added 3d printed slide to this video.

    • @SIGMECHANICS
      @SIGMECHANICS  7 місяців тому

      Merry Christmas to you and your family! I believe making a larger/taller ledge might lead to instances where the P320 might not fully lift the lever all the way. Each trigger system SLIGHTLY varies due to manufacturing, the chosen ledge height was probably engineered as an “average” dimension that “just works”. This is however just an opinion as I don’t have the data on hand.

    Noticed once you start playing with pretravel screw manual safety starts getting stiff and crunchy. I have mine before it gets to that so about 2-3cms unlike others who have theres down to 2mms

    • @SIGMECHANICS
      @SIGMECHANICS  5 місяців тому

      The MS works by creating a stop on the trigger bar from moving. By pulling the trigger, you are essentially pulling the trigger bar slightly forward if you were too adjust pre-travel, it is essentially the same thing as pulling the trigger. Therefore, there is a correlation between setting the pre-travel screw, and the position of the trigger bar.
      That being said, it’s very possible that by moving the trigger bar, you are not allowing the manual safety lever to drop down into the cavity of the trigger bar the way it needs to for a smooth transition.
      This is just a theory, of course as I haven’t Particularly tested this issue.
