Does anyone know when/what date Sig began selling new pistols with the upgrade included?
Or is there a beginning serial/model number of pistol that had the update included?

Thanks all

My P320C RX has a born on date of Nov 17, 2017 on the box and it has the upgrade.
It's a good pistol, too!
And, "Welcome to the Forum."

Thanks "Arty". I was at a gun shop today and was looking at a P320C-RX, like the one you have. The sales person told me the date on the package was late Nov, 2017, forget the actual day. He described what he thought were the updates and indicated the one they have has the updates. I guess I am thinking the gun is already five months old just sitting there. Perhaps if I had them order one from Sig there would be no question as to whether it had the updates. Seems curious to me that Sig has not produced the range of serial numbers of pistols that qualify for the update.

It's actually quite easy to determine the old components vs the new components. First there is the physical change to the trigger, which is quite noticeable. But many are not familiar with what the trigger looked like before.

Then there is the trigger pull itself. The previous design self-resets with a click every time.

You can also take the top end off and quickly determine if it has the new parts. Strader did a video on this subject for those not yet familiar, but the sales person should also be able to quickly identify.

Thanks Steve. Do you have any information when Sig started putting the upgrade in new pistols?

No, sorry I do not. To my knowledge they have not published any serial number change points either.
