P320 Subcompact 9mm range results and ammo selections. Pictorial review.

That is Sig's current MO. Look at the time between changes in the M&P line and the Glock line. There is ar much longer timetable. Yes gen 4 Glocks Had issues but other do not have the same history of beta testing that Sig does.

Sig unfortunately pushes product to market and let's the buying public work out the kinks repair issues under warranty and revise the pistol knowing most will not have a problem or more importantly get shot enough to fail. IHMO YMMV

On the M&P? Not really. On Glock yes, but S&W has so many changes that I honestly have a spreadsheet to keep track of them (not to mention multiple changes of a single part). The SA XDS recall was very soon after release and was a safety issue. We could talk about the Caracal release too where the whole pistol line was recalled and supposedly unfixable requiring a complete revamp of the design, again for safety. We have no confirmation that safety is the problem here or even that the change was due to widespread issues. One year after initial introduction isn't overly quick for a first reexamination of the design (I still can't find pictures of this change but I keep trying).

Had issues but other do not have the same history of beta testing that Sig does.

I think it has more to do with not fully testing a design in house than using the public as beta testers, and as I've pointed out we can find an example of this behavior with most manufacturers today. I don't think it's a conscious design to put consumers in harm's way. I am not excusing the behavior, but I am pointing out that SIG is hardly the only one (though at times perhaps one of the worst offenders) and we have no evidence that is the case with the P320.

I believe that is exactly what I am saying. Sig does not fully test the new designs that they are releasing to the public. They let them leave the factory as somewhat unfinished and the public works out the kinks and helps them correct issues. I agree too many people do this these days but Sig is one of the worst and sell their guns at a premium price.

I also think there is a difference in changing a singe part than redesigning the control unit in a modular pistol where the control unit "is the gun".
 
This is kind of like saying "where there's smoke there's fire" and there isn't even any smoke in this case. I don't like to deal with hypotheticals because the Internet has a way of twisting it into misinformation.

I believe that the out of battery issue with the gun on the Sig forum was a issue with the barrel and slide geometry.

I do not think there is danger here but I would like to know why they changed the control unit and exactly how it changes the function of the pistol.

PS the trigger has been changed since the Ayoob review. A small percentage of people experienced trigger slap.
 
The tab I mention is on the other side of the FCM than the one you can see in the pic.


On their site... One of the little click able plus signs will mention it and show it.


The tab I mention would or can disconnect the trigger bar from the sear until you release the trigger... Just like any other trigger disconnect.

I agree with you to an extent though I would point out the P320 isn't a very premium price compared to the competition.

As for redesigning the entire fcu we haven't seen that yet. It may just be a different trigger bar on the fcu. Also keep in mind the whole fcu concept is relatively unique to this design and replacing individual parts may be a weakness in that concept depending on parts availability and ease of replacement.
 
It is the if evolution page... I think it's the first pic with click able areas, the pistol points to the left. The click able area is the lower rear one.

It will bring up a picture to the side and talk about out of battery safety. That black trigger bar is not the same as the one on my pistol.

I am mostly just curious to the change and how it affects the function of the pistol as a whole.

As I said the 320 has a different trigger disconnect from the majority of semi autos. I am wondering if this change also affects the function of the trigger disconnect as well... It would actually make it easier to tune the pistol for competition shooters.


I also added an edit to my prior post adding some info.

Disconnect Safety

Prevents the pistol from firing out of battery.

Here is a pic that has a trigger bar like mine.

Here is the new design.

Other than that, I have noticed a running change in the way the FCU is assembled. They changed a retaining pin, and made the deign easier to assemble and disassemble, by making the pin go through the whole frame and not just in the sear block and hidden until you remove more parts.
 
Besides that concept image, have you seen an actual image showing the change though?

Nvm I see you posted it. I was totally off spatially in my mind and I have no idea why. I wonder, does your slide then not have the cutout for the disconnect? I'll have to check mine when I get home.
 
What's the production date on yours marine? The image you posted with the different trigger bar was uploaded 1/2014. That's pretty much the beginning of the release. I wonder if there are two different versions intentionally? I would think you'd be able to order a replacement trigger bar if desired.
 
My slide has no cutout for the trigger bar tab. And from memory it was made in May last year. I got it in June when they first showed up in my area. (well PSA had them online, and had it sent to their local store)

That pic I believe is of a prototype from before production.


So the change or the idea at least was floating around since the start.

All the reviews and pics I have seen so far are the same as my 320. So the new version may not be out in the wild yet.

I don't think it is a instance of two different types in the wild from the beginning.

To do so would make the caliber change/range to carry kits a sticky situation... Order one not for the old trigger bar and your pistol would not work if of have the new one.

So if they make this change, then all new slides have to be cut for it, as they would still work on the old style.


Knowing how the trigger functions with the new style trigger bar would be very informative for my understanding of the system as a whole.

Valid point, thanks!

I'm finally on the same page with you. I thought you were discussing a change that had already been confirmed in the wild so I kept looking for current pictures that showed a comparison and found nothing. I agree it's sort of odd to advertise it on the product page and not have it in production. Maybe a decision was made and no one updated the product page?
