I need a picture or diagram of current P320 Striker Assembly parts. The schematics out there that I can find are pre-upgrade and are no longer accurate. The excellent SIG Parts Finder just shows the Striker Assembly as a unit.

This is from the armorer manual of a course given in October 2018. The manual shows the disconnector and therefore it is after the upgrade.
(Sorry about the size; it's either too small or huge like this.)
Added: FWIW, I checked the manual for an April 2017 armorer course and the illustration for the striker assembly is exactly the same. The “upgrade” therefore evidently had no effect on the striker assembly.This message has been edited. Last edited by: sigfreund,

Howdy! The voluntary upgrade brought a few minor tweaks to the striker and striker housing. Most notably, striker mass is reduced, and the striker housing now features a pocket to help retain the striker lock. The most critically important upgrade changes are found in the FCU itself. I hope this helps.

Indeed it does.
In my spare parts supply I have two different strikers and I noticed that one evidently weighed less due to grooves behind the firing pin. It didn’t occur to me that that feature was part of the upgrade. As I mentioned, the illustration above that appeared in the armorer manual after the upgrade is evidently the same as the previous one and doesn’t accurately reflect the appearance of the lighter striker. I imagine that wasn’t considered important for the purposes of identifying the part.
Do you know if the older striker is usable in the upgraded guns?
As always, thank you for contributing your insights. These are the sorts of details I find very informative.
