It's under no pressure, it's a V cut, and doesn't extend the depth of the striker channel.

Since I have both sitting here.

Updated trigger top, old trigger bottom.



Old slide left, new slide right w/ new cut being pointed out.

If it has a build date of Nov 2017 forward, you'll be good.

Skinny trigger is another clue, unless it's been changed. The v notch below the extractor plunger is definitive.

Amazing how the upgrade cleans the trigger up. I wouldn't have thought it was possible. Also got rid of an issue I'd see in about 1 of 100 guns, a little double catch (for lack of a better description) in some triggers.

You may be pleasantly surprised at the turnaround time.

Two schools of thought on that. 1) yes, wait until initial rush dies down, 2) beat the rush before news goes wide. We like to think everybody knows, but really at this point it's just the enthusiasts who browse gun forums or gun news sites.

Apex will give you a credit for the trigger. I'll dig up details on that later.


Sig has republished the Voluntary Upgrade page:

https://www.sigsauer.com/support/p320-v ... e-program/

Details were up, but Sig pulled the page down. It's Voluntary, but all new production 320s will have the update. LE and retail will get details later.

From what they had posted - details could change when it returns:

Updating: Trigger, Sear, Striker, while adding a mechanical disconnector. There should be no meaningful or significant change from the current 320 trigger pull.

1) Fill out the online form, you'll need your serial number and home address.

2) Sig will contact you. Return is free of charge. Shipping to Sig may also be free. It said it was deeper into the page but not at the top. Will have to see if that's still the same when the page returns to Sig's web site.

3) Turn around time will be approximately 4 to 6 weeks.

Take all your personal stuff off the gun (aftermarket sights, magazines, triggers, lights, lasers, grip sleeves) as they won't guarantee its return.

The entire gun has to go.

Have an exchange kit, send in the slide. Striker has to be replaced and, "the disconnector cut." That last bit intrigues me.

X series 320s are affected, but trigger will not be replaced. It's already lighter than the stock trigger.

Details on the voluntary upgrade program for non-LE guns.

Edit: I did have a link to the page - but Sig pulled it offline.

Imagine being on the retail side. I've got 60+ 320s that are for LE/First Responders only.... Looking forward to some details myself.

Never-the-less, still carrying my P320 and you'll notice that HPD hasn't pulled the gun from service.

The most dangerous part of dropping a pistol is not the drop - it's trying to grab the thing. I've dropped one in my life to date. Not a Sig. It's a hard instinct to fight that's sure.

Comments and slides direct from folks who met with Sig this week.

This is the most detail I've seen to date:

The new LE 320s I've seen from March 2017 on have all had the new skeletonized striker. There have been incremental upgrades along the way. We'll know within a week what the full details are.
