Is the P320 market dead?

[Walmart_AR15]

I'm not a patent attorney but I saw this on X. Looks like Sig redesigned their striker assembly in 2020. According to the abstract it was to stop the striker from slipping due to an "impulse". Maybe smarter people than be can explain if this is what it looks like; they quietly redesigned the striker.

That was part of the first SIG upgrade after the drop-test failure. Thus, the current issue is with this modification already implemented. The 2nd notch does not catch the striker, and the striker block failed.

SIG should have made the 2nd notch a bit taller and more positive catch (hook) than the first notch; the patent shows them to be at the same height. As is, when the striker slips off the first notch, it would just slip off the 2nd notch as well. SIG had assumed the sear would move when the striker slip off due to impulse.

So how has the design changed because of that?

Yes it has. 1 pin, then redesigned to 2, now 3 pins for strength, etc. There was documented issues of Police Weapons having slam fires in Gen 1s, “6 part upgrade “ for Gen 2s (did not state “recall” but you would send in pistol and Glock did replace the parts for free), early .40 models had issues feeding, extracting and the case being unsupported led to some “kabooms Gen 1 fully loaded mags stuck and no drop free in grip due to no metal liners inside mag body, Gen 1 mags falling out in some models w/o pushing mag release.

There are more known issues, but you can look them up yourself.

Now they're back to 2 pins. I don't think that has anything to do about guns going off in the desert. Gen 1 mags weren't metal lined, that doesn't cause a safety issue though.

How can a Glock "slam fire", they haven't changed the striker safety block, right?

I think some of you old timers on here are being disingenuous when you should be imparting wisdom. Disappointed.

I was not the one who said they went off in the dessert by themselves.

As far as everything else I stated, before dismissing it out of hand, do just a little due diligence and you will see the issues I mentioned documented.

Do not take my word for it, literally two minutes on the web browsing will show you. If you prefer to just go with a feeling, guess or assumption then so be it.

At this point I’m figure you for a troll. You attribute the “Going off in the desert” to me to support your claims but that remark was made by another member, not me. I only attested to the fact that the Glock did have issues previously and then stated some of the issues, not all some.

Then you cherry pick one small tidbit from a long list of items I mentioned to again, disprove the Glock going off by itself in the desert which is not my statement nor did I say that was true. Again I just attested to Glocks previously having known issues, but you continue to have selective reading skills.

Then, to try to disprove my statement you start by saying, “I think” not “I researched”, “I am a gunsmith,” etc once again to bring up the friggin desert scenario.

And you’re the one disappointed, huh.

If I remember correctly, all the alleged "uncommand discharge" from Glock was later proved that the trigger were pulled by the user. It is physically impossible to discharge a Glock without trigger bar movement since the striker is "cocked" by trigger movement. With a round in the chamber, Glock striker does not have enough energy to ignite the primer if falling off the sear.

The "pins" were due to the plastic frame cracking when moving from 9mm to 40 using the same 9mm frame.

Slam fires were due to the striker getting stuck (cleanness comes to question). Striker sleeves were added.

Extraction/feeding were issues with the extractor. Kaboom due to case support is questionable due to the ammo source, new, reload, etc. For a while there where this Glock smile thing going around. But as long as the ammo were factory new, there weren't real problems.

Glock never had the same issue that is now facing SIG P320.

Firing in the Holster was from cops using old, unserviceable leather holsters. The leather becomes soft over time and was able to bend into the trigger guard during reholstering causing the gun to go off.

Not a design flaw, was end user maintenance and being lazy/cheap replacing holsters.

The NY trigger, which wasn't a trigger but a plastic spring, wasn't to address a design fault.

I would hope that senior members of the CA firearms community could be more honest in the retellings of history.

Glock's problems in the early 90's, which are mirror-like to Sig's problem in 2025 is a well document fact.

The NY Trigger was indeed not addressing a design fault, but rather an ingenious response to address a different kind of fault that has existed since the beginning of time. Amazingly, both the problem and the NYPD Trigger went away.

 

[Jlg23]

SIG engineers probably already have fix but just not publicize or rolling it out. By doing so would admit P320 had a problem, then the land slide law suits. At the right time, SIG probably will advertise some trigger upgrade in the future and will bundle the fix with it.

Yea I’m hoping they’re cooking up a solution in the back. But man did this do damage to their reputation

 

[cali_jazz]

At this point I don't see how Sig can not reply, there is just too much pressure. They are in a bind after denying there were any issues, if they admit it they will have to spend a fortune on a recall/fix and pending litigation, if they continue to deny they are likely to be class-action sued with a similar financial outcome. In either case their reputation has been severely damaged.

I'd buy one to have it shoot me uncommanded and cash out

 

[remusrm]

All Off Roster P320 Purchasers/ Owners when P320 got added to Roster...

And current CA/P320 Owners...

its seems like it... i never considered one but shot a friends, also i do not believe round in the chamber is smart without manual safety!

Saw the above videos, and it seems the lighter one seems to giggle more

 

[sklepych]

any known cases of UD when the manual safety is engaged?

Not even close. Glocks never went off being bumped in the holster, and out of battery detonations and drop issues. This is bizarre statements.

 

[AR15barrels]

If anyone wants to get rid of their Sig P320 let me know. I'll give you $320~ for it lol.

I paid $299 for one 3 years ago.
With the case, manual and 4 mags.

 

[AR15barrels]

any known cases of UD when the manual safety is engaged?

There could be.
The manual safety does NOT restrain the sear and these UD's are from slop between the slide/FCU and the striker/sear.
The manual safety only blocks the TRIGGER so it does nothing to mitigate the 4 factors allowing the UD's.

On almost all other firearms platforms with manual safeties, the manual safety blocks the SEAR so that the hammer/striker can not be released.
This is one major departure that the 320 has over almost all other platforms.

All guns go off by themselves all the time.

Even a hundred years ago they did. The military rejected the original 1911 design. So a grip safety was added to ensure that whenever a gun went off, there would be no doubt as to who caused it. Yet in 1979, my uncle's 1911 went off and grazed the skin off his right testicle. It also burned off about a quarter of his pubic hair. He said the gun went off by itself.

 

[Plenty_Pack_556]

P320 main issue was being modular. This gave users too much options to deviate from original design in which was too hard for holster manufacturers to come up with a solid P320 holster with so many variations, which led to bad holstering of P320, which leads to poor fit and thus creating problems.

I'm sure no one talked about it this way, and I am probably the first to bring it up specifying it to this issue, as in y'all heard it first here lol.

Did they say something similar?

 

[Subotai]

It's like this. You can carry a 1911 without the safety on. It might not go off. For most people, it probably won't. But, it will happen to some. Do you want to be that guy? Not me. Traded it in at a loss, picked up an M&P Compact 2.0. And from what I can tell, it's a superior weapon. And I'm a SIG guy. :/
