I’ll be honest, I didn’t notice. I may have accidentally cut it out of the video without realizing it. I’ll take a look. Thanks for bringing it up.

@SIGMECHANICS I was just wondering hey now that I got your attention why do you think my safety lever gets stuck in the back position and don't let my mag in so I have to push it manually with a punch through the ejection port every time I take it apart. Also what does that safety lever do of what is it really for? I have not found any videos on that. Thanks 👍 and great content keep it up.

@ It shouldn’t be. The safety lever is loose fitting and is controlled by the trigger pull… Watch this video to get some insight on the function. (Skip to 7:48) kzbin.info/www/bejne/jJ7aoZ6Aqq6FZpIsi=2LnkjJhOCzB0VdpS If after watching it does not make sense send me an email with a quick video of the problem to [email protected] to see if we can figure it out together.

You’re very welcome.

?

The funny thing is, for me… the skeletonized factory is my favourite!

What seems to be the issues?

I believe it’s 105mm

That slide movement is normal and here’s a video giving you the full rundown about why it occurs: P320 - SLIDE MOVES DURING DRY FIRE kzbin.info/www/bejne/n6WqoqSnba6Wgpo I’m not sure why you can’t replicate it now however but it’s not a concern either way.

Yes, but I have to do it manually, the website won’t let it happen. Send me an email to [email protected] and I can set it up

Hey! Thanks for watching!! I actually have tested your first point, it didn’t make a difference as there is too much distance for it to move to disconnect from each other. It does move but only a fraction of a tiny distance. I will definitely test point 2 to see if I can ignite a primer but I do know that to make it come off you still need a full trigger pull to do that so partial pulls wouldn’t affect it. Thanks for your insight!!

This wouldn’t release the striker over and over, it only simulates the action. The project has started to move a little now that some other things have cleared up.

I’m definitely not here to sell you on it, all I can do is provide you the data I find as I work on projects. If you’re on the fence I’d say try it with a MS first until you have some time to manipulate it and put it through its paces, after that consider removing the MS once comfortable. If you end up picking it up and have any questions feel free to shoot over a message to [email protected] and I’d be happy to help!

Thank you!

I disagree in the sense that what he pointed out wasn’t substantiated by anything other than court docs of which are intended to be used against Sig Sauer in a case, but he didn’t provide any proof of the claim (anything that can be tested and proved by a third party). He also seemed to not understand the purpose of the second sear ledge which makes me think he’s research is only based on the arguments being made in court docs. That being said, I’ve tested this by manufacturing a 1:1 striker and sear, (with sharp cut edges) and ultimately the slightly rounded edges of the striker is critical for it to roll off the edges off the sear, sharp edges makes it hard for the parts to dislodge (once they are both sitting at the absolute edge of each other just before the break). I feel like this means that the rounded edge is part of the design of the striker. I might make a video to show this as evidence of that.

@SIGMECHANICS appreciate your feedback. Ive been leary of carrying my P320 and so I've switched to full time carrying the P365. Which protraband shows how it differs in design. Taking a deep dive watching all your P320 internals vids to see deeper if my fear is reasonable or not

@SIGMECHANICS were you ever able to get the second sear ledge to catch the striker through really strong hits or vibration? I know you've done a half-recock, but just curious. I figure if the second latch inconsistently catches the striker as a drop safety or wear and tear safety, that could be where people should point to for explaining accudebtal discharge.

I’m not sure but just in case… Sig Mechanics is not endorsed or affiliated with Sig Sauer. If you want to pass along a message or request you’ll have to contact Sig directly.

Not really. Though I haven’t gone down the rabbit hole as to why it happens in the first place. Seems like if you pull too hard on the lever it dislodges the bar from its housing. (My opinion only)

@@SIGMECHANICSthanks man coz I am in debate on buying that or a P2000. I like to get XMacro, but there are some negatives I saw online, coz I will be letting go of my XD9 (California) so I want one that I can leave in my bugout bag for a very long time.

I watched it (because of the title), but unfortunately the video didn’t ultimately provide any proof of anything that I could use to test or reproduce a method of testing it is mainly conjecture based on images from court documents, but it was still not proof that the claims were real and some information was wrong or misunderstood (ie: the second sear ledge isn’t going to stop the striker on a trigger pull, only in a situation where the sear drops and the sear springs kept continuous upward tension). In any case you are correct the FCU as far as we know can only fire on a trigger pull, and having a MS compounds the safety in a big way which you can see more details about here: kzbin.info/www/bejne/l5-9mGeYYrZ_iKMsi=F6X05TN8YjuzFNtS I hope this helps!

Yes it does work with it.

Technically, they do with the M 17 and M 18.

@@SIGMECHANICS What I was getting to along my scenic drive, was the slots for the manual safety should be cut (Stamped) in to the FCU frame of all P320 FCUs. But fortunately for you they don't, so the aftermarket has something to do!

@Hibbie2963 ah! Yeah I completely agree, it’s such a simple add on to their stamp!

What do you mean?

I thought about broaching the subject, but I ultimately didn’t want to focus on that since this was supposed to be educational and I wanted to leave out opinions and possibly leave questions unanswered. Truthfully, no one has proven the UD claims so it’s my opinion that such a thing does not exist (unless someone can come up with a repeatable method of replicating the claim).

@@SIGMECHANICS Bruh there are numerous videos of them discharging in holsters when cops get out of their cars.

A small degree, the 365 is still vastly different though they “seem” similar due to the FCU.

I watched it because of the title however… Although it was compelling as a story, most of that video was images of documents that don’t provide anything that says (for example), a sear ledge at X.XX” depth + a striker hook with XYX” radius edge will cause a discharge. Nothing was provided that you can take back and create a honest method of replicating it under a controlled environment. Also there are also some issues with some of the data provided in that video (like how the second sear ledge is supposed to work), which although I understand how they got to that conclusion is not exactly how it’s intended to operate. I only say that to say that I’d refrain from using that video as the “final say” on what’s being claimed being true. Real testing needs to happen first. To answer your question, I don’t think there is anything wrong with the design. I actively research things by testing theories as they come up and I have yet to ever actually “prove” the claim, although I always remain open to changing opinion with evidence. I’m still very confident with the P320 and still enjoy using it.

@ Thank you, sir. Sorry I forgot to add the disclaimer about a large chunk of the video (approximately 8 min to 58 min) being irrelevant to the gun design/striker function.)

I am thinking if someone made a milled striker safety lever. With nice crisp edges instead of a stamped one. That might ease the minds of some p320 owners and could probably make some coin. 🪙 The pictures from the sear on the p320 that went off in the purse incident was a little eye opening. 🧐 Edit: and maybe a stronger safety lever spring as well. Would likely change trigger feel but I wonder by how much.

@suddendilemma5137 There’s a trade off here. I have actually made a 1:1 CNC’d striker with perfect angles but due to the sharp edge the sear and striker have a hard time releasing from one another. To operate effectively it needs a very slight radius by design to work. People shouldn’t take that video to heart, there’s a bit of bad info there and there’s no actual evidence of proving the claim in the content.

@@SIGMECHANICS that’s so funny. Figured if anyone out there was playing with it, it would be you. 👍🏼 also I could imagine those two faces hanging up but also little surprising, as I wouldn’t have thought there wouldnt be enough pressure to bing them. The design seems reasonable and your videos are second to none as to how that safety works. Short of the striker safety spring breaking or leg missing it makes no sense how these pistols are going off. I wish there was more detail also as to if they were factory triggers or not, the condition of the firearm, just more info in general.

Thank you!

Thank you!

That’s not much information to work off, but my first guess would be something’s wrong with the guide rod most likely it’s installed improperly.

@@SIGMECHANICSso I can’t get my slide off. The guide rod is sticking out probably 1/16” past my slide when I do the take down. My slide catch also is not working. It clicks going up and clicks going down but does not work. I’ve been messing with it for a few days but will probably just bring it to my local gunsmith today

@AlexBaus-g8s you can always try to pull the guide rod with pliers (use something to protect the metal), and give it a 1/4 turn. Release and test.

No, but also the X-Ten has all the same components as the 320. Honestly, there is no discharges happening here, only inadvertent trigger pulls.

@SIGMECHANICS I've never understood how if it's such an issue why it cannot be duplicated - maybe I'm missing something, but I really enjoyed your video and I'm getting the Xten. Thank you!

Thank you! Absolutely, I have tried every way from Sunday to try to manipulate this thing to do anything outside of the ordinary. Including removing safety features and giving it every opportunity for catastrophic failure. And to this date, I cannot get the P320 to go off without pulling the trigger. Unless somebody can bring me real proof with a repeatable method / process of causing the so-called issues, I stand firmly that it’s safe to carry.

@@SIGMECHANICS nice, after watching some of your videos my questions have been answered, I appreciate your hard work here!

And your equipment looks top of the line. This is great work. Really incredible.

Yes it will!

If this is for the P320, I do have a video regarding what to do if your slide get stuck. Here’s the link: kzbin.info/www/bejne/g5u1ioWKfMplm7Msi=gHUBYKlOSYamUdwm

@SIGMECHANICS yeah its the worst things happend, i already seen your video before this, but i was thinking to remove forcesly the takedown lever inorder to remove the slide together with fcu and after that i will buy a another parts for takedown or machining the takedown lever to reused it. I appreciate your channel and it help me alot.

@toothlessmegalbio to do that you’d break the grip (the FCU sits within notches), there is no need to force anything on the 365, it can be done gently for the most part if you pay attention to the mechanics involved. Your situation sounds to me like either your guide rod was inserted wrong or you need to move the sear out of the way to just release the two parts from one another. I’d need to see it personally in order to really determine it though.

@@SIGMECHANICS i already removed the striker in the slide, about the rod they inserted it reversely, i also pull the rod to release its spring preasure, does the notches will be contact to the slide even there is no striker in it?, this is very challenging one.

It’s slowly happening! I’ve got another project that sort of opened the door for this one to start back up but it will take some time.

@@SIGMECHANICS Gotcha, until then it's rack click , rack click :)

It’s possible but from my understanding people claim that’s happening on stock P320s. Regardless, no one has proved the claim yet so ultimately I believe the trigger is just being pulled by accident.

I know you’re just joking but I just want to note (in case someone newer to 320s finds this post), that to date, there hasn’t been anyone that has proven the claims of uncommanded discharges. However, in 2017 there was a proven drop safety issue - however since then it was solved when they swapped the heavy trigger to a lighter one which stopped the trigger from moving back due to inertia when dropped at a 30 degree angle.

Lol theres video evidence of p320s going off in a holster without it being touched. SIG was also found negligent and liable for the design. ​@@SIGMECHANICS

Thank you!

Did you have a specific issue that made you think this way?

What do you mean?

@SIGMECHANICS Sig IMHO shifted its focus to plastic strikers and mostly abandoned hammers. The P365 could easily be turned into something similar to the P225. A small metal 1.5 stack hammer fire. They totally abandoned the 357 sig caliber. You can't buy a milled P226 slide for a 40sw legion. I'm heavily invested in their line, and they've become a disappointment.

​@SIGMECHANICS the only videos I've browsed through here are on the 2 newest line of strikers. P320 which is difficult to give away ATM and the P365. Nothing on the P229,P220,P226 or discontinued models. It would be nice to see a bit more variety if the channel was created for SIG products and not just 2 pistols. I own a 320 and 365 so I do enjoy what's posted.

Hi! I got your message. Unfortunately I don’t share them with others because the files are very detailed and are technically manufacturing “ready”, so I don’t share them as I don’t know the legalities of supplying 2A part plans (which vary state to state).

I haven’t really considered it. I definitely can, but it took about 1 year to obtain every trigger!

Thanks! Happy to be of service!

Thank you!
