P320 Upgrade

In case anyone is interested, I have a report on sending my P320 back to Sig for the “voluntary upgrade”. I registered a couple of months ago and hadn’t heard a thing until Thursday, December 7. I received instructions on how to pack the gun for shipping and how to print the prepaid shipping label. I dropped the gun off at a main Fedex hub (the smaller offices won’t ship firearms) on Friday, December 8. Sig received the pistol on Monday. I got an email today (Saturday, December 16) telling me that the pistol was on it’s way back. It is scheduled to arrive on Tuesday. Pretty fast turnaround. I’ll post my impressions on the upgrade after I have a chance to get to the range.
 
My understanding is the upgrade will not mess up the Great Trigger the 320 has. A good thing. A Deputy buddy of mine has one. I am pretty impressed with it.

It it just the luck of the draw, mine took 5 weeks.

The trigger was slightly lighter, never shot it with the new trigger, I traded it away.
 
I had two upgraded. Door-to-door turn-around time was just over 3 1/2 weeks for the first and just over 2 1/2 weeks for the second.

As for whether trigger quality is better or worse post upgrade, I have mixed feelings. The main difference that I can appreciate is that the trigger breaks a bit lighter on both pistols post upgrade. This is a change that might be welcomed by many, but I was one who felt the P320 trigger break was a bit too light to begin with.

In dry fire, comparing my first upgraded pistol to the non-upgraded one, I felt that the take-up on the modified trigger was a bit smoother, although no shorter or longer. The reset was also a little more positive and audible for the modified trigger. These are not differences that I can appreciate in live fire, however.

Apart from the lighter trigger pull, I felt that the quality of the break was about the same. Some have described the break as "crisp". I think they have low standards for crispness. Although I felt that the P320 had and has a good trigger break for a striker-fired pistol, I have yet to shoot a stock striker-fired pistol that did not have a break with at least some creep. The amount of creep in the P320 trigger break pre and post-upgrade seems to me to be the same.

The first time I shot my modified P320 full-size .45 ACP in live fire, I experienced a significant degree of trigger finger sting after shooting less than 20 rounds. This was outdoor shooting on a fairly cold day. The second time I shot the same pistol, I did not have any actual discomfort in the trigger finger after 30 rounds, but did have some tingling which might have gotten worse if I had continued to shoot. I also had one round fail to feed. This was Winchester white box 230 grain FMJ and the failure to feed may well have been ammo related. But I had shot plenty of the same stuff prior to the upgrade, and this was the first malfunction for that pistol.

A few other individuals have reported trigger finger sting after the upgrade. This might be more common with the .45 ACP pistol. I had never experienced the same phenomenon with the pistols before the upgrade, both of which came with the second-generation "adverse" trigger.

When I shot my modified 9 mm P320 compact I did not experience any trigger finger sting. But I did have a lot of cases ejecting straight back at my head, which this pistol had never done before. I had only done a cursory inspection of the pistol before shooting it to make sure it had been lubricated. When I got back from shooting it, I did a close inspection and cleaning. The ejector looked fine, but there was an incredible amount of gunk on the breech face and under the extractor claw. This did not look like the typical carbon powder residue. I think it was metal debris from the slide milling process. I have not yet had an opportunity to shoot that pistol again after cleaning and relubricating it. I sure hope SIG has not modified my pistol to hit me with hot brass with consistency. I already have a Gen 4 Glock 19 that will do that for me.

Upgrade

My previous trigger pull was awesome, I had no issues. I made a bad mistake getting rid of it and my new P320 Carry comes lighter with the new trigger. Its lighter and more ergonomic. As a reference Apex triggers has offered a full refund to purchasers because the new trigger is so close to theirs that they are offering a full credit for trade in. Clearly its a trigger upgrade.

From other Forum posts on the subject the 45's take longer with the "Voluntary Upgrade!"
It seems that there is more milling of the slide on the 45's.

I've heard the milling argument. I don't really buy it. The difference you're talking about on a modern mill should be on the order of seconds. Certainly not anything that would translate to weeks worth of delays. I'd be amazed if this wasn't being done with CNC programs.
 
my p320sc grip frames

the new sc grip frame is a little bit longer than the old one. What is the reason for that, anyone know ?

The tang on the subcompact P320 frame was always very short compared to that for the compact, carry, and full-size grip modules.

The P320 when drop tested with the muzzle up and barrel vertical passed the standard industry tests because the tang on the grip module protected and buffered the rear of the slide from direct impact. When dropped muzzle up with the bore axis inclined 30 degrees to the vertical, the tang no longer protected the rear of the slide from direct impact and it was shown that the unmodified pistol could drop fire.

The presumption is that the new subcompact grip module has a longer tang more in line with those of the larger models to better protect the rear of the slide from direct impacts.

(emphasis mine)

True! There was no court order mandating the action by Sig, they acted voluntarily to replace and upgrade the parts in question.

Even a court-ordered recall can not force individual owners to return their product, they have to return it on their own volition (voluntarily).

...The trigger was slightly lighter, never shot it with the new trigger, I traded it away.

Too bad for you, Sig did their part and did it well. Maybe for some, there is no reconciliation.

I guess I'm not one for patting SIG on the back for the "voluntary upgrade". It wasn't something done proactively. It was done in response to a lot of bad press and not doing it would have continued what turned into a PR nightmare (we can argue if the extent of the bad press was extreme). I also have some questions about the fact that the fix already existed as a change request to the military pistols. To me that begs the question of if/when SIG knew about this potential issue, and if so would they have upgraded existing pistols if all the bad press hadn't happened or simply rolled the upgrades into the newer pistols with no word as to why.

Because it was an upgrade rather than a recall I still see P320s at retailers being sold as new with the old triggers. Meaning the owner then has to ship back that pistol right after purchase if he/she wants the upgrade. That could be the fault of the retailer, but to me it's a bit of a half measure on the part of SIG.
 
I happen to be looking through the manual on my ruger sr9, it not only states that if the pistol is dropped it could fire, it shows a picture depicting the angle and manner in which it could fire and it is exactly the same as the sig. i dont see any recall or upgrade from ruger, i dont see any outrage from consumers. If sig and ruger have this “flaw” , how many others do? My guess is this is much more prevalent than people think.

The owner doesn't have to send it back to Sig for the upgrade. Frankly, if I was OK with the trigger, I wouldn't bother. In no way would I be concerned with the "drop fire" issue.
 
new grip vs old grip

People hijacked my original post, so here is the picture.

From what I learned, Sig had modified the trigger for the P320 (M17/M18) at the request of the DOD. Sig Sauer was going to use the same design in the commercial pistols as production ramped up for the military. The M17/M18 has several features not found on commercial models. It would make sense, in this case, to produce one design of trigger for all and save on production costs since this upgrade would be of interest to the civilian market. All this was well before the DPD/YouTube blitz.

The nightmare' was started by a false claim from an armorer at the Dallas PD that was leaked before anything was verified. The YouTube warriors went for their 15 minutes of fame and subjected the P320 to severe testing outside industry protocols. Sig responded by offering the free upgrade within 2 weeks of the first claims. For any industry, that response is near speed of light.

At this time, no handgun in the world has been subjected to as much testing or is currently being tested as much as the upgraded P320, making it the safest gun on the market.

Well, except maybe the Honor Defense Honor Guard pistol which is now being hammered in oblivion.

I hope this helps clarify some things for you. Hopefully, you will find confidence in your next pistol.
 
I knew all of that already, as well as the lawsuit from the CT police officer not part of Dallas PD claiming that he was injured by a falling P320 (which hasn’t been decided last I knew and may well be a false claim to mask a personal mistake). I don’t know how you can say that no other pistol has been subjected to as much testing, or that it’s the safest gun on the market. That seems a bit hyperbolic. Both the Glock and M&P passed the test the P320 was subjected to by the same people. I’m not sure I consider dropping a pistol at an angle from the typical height “severe”. To be fair to SIG though they did pass the standard tests and to me that says the standard suite of tests is lacking. I don’t doubt the SIG is quite safe now, but “most tested” and “safest”? Those are bold claims.

I don’t really want to take this thread off course from the OP and we’ve covered a lot of what has been said in previous threads. None of that changes my thoughts above. If you feel differently, which seems to be the case, that’s fine. I’m simply making my opinion heard.
