Do you really think that Sig set out to eliminate the click, or that it played any part in the "upgrade" development or decision tree?

I doubt that.

Personally, I like the click.

I don't think Sig cares if I like it, either.

Yes, I think SIG intended to remove the double click.

The change to a disconnector doesn't have anything to do with a drop. Perhaps the word is misleading people. Understand that the trigger either includes a sear or interfaces with one. The sear holds the hammer or striker back. When the trigger is pulled, the sear is released, the firearm fires. With the trigger back, the sear wouldn't catch again and the hammer or striker would follow the slide or bolt forward. A disconnector catches the hammer or striker and holds it until the trigger is let off. The reset is the sear reengaging and the disconnector is disengaged. Now the pistol is ready to fire again.

The original P320 design resets the sear on the second click. Somehow, it also disengages the trigger. The reset is the trigger reengaging the sear. I don't see of a reason to do this instead of using a disconnector, other than just to be different and clever. I feel like it's one of those things where they were more concerned about if they could do it than whether they should. I kinda feel the same about the lightened trigger in lieu of a tabbed/hinged trigger. I feel like there's ego or a desire to be different at play.

But I'm also no firearm mechanical engineer. Maybe they had good reasons.

SIG did not set out to fix the “double click”.

Then why add a trigger disconnector?

TTAG reported it was to change the double click: https://m.youtube.com/watch?v=eWCiPnTU8PA. You can fast forward to 1:18.

I obviously wasn't invited to SIG to check out the upgrade, but TTAG was.

There was already a magazine disconnect to prevent firing without a magazine inserted and a trigger bar disconnect to prevent firing OOB. Why add a trigger disconnector if not to remove the double click? And maybe it's semantics, they didn't set out to remove the click but rather make a more traditional function, which by its nature removes the double click.

Good for them. The evolution of what we are seeing now cane from independent R&D and it had nothing to do with the double click hysteria. One step further, the disconnect or was T&E’d long before the internet double click hysteria became a thing. And I can tell you that for a fact.

Guess what? There are a multitude of things in T&E right now. We may see some incorporated into future evolutions, we may not.

People can choose to believe what suits them, or what drives whatever narrative they wish.

But, the above is about as close to the horses mouth you’ll get unless the actual designer chooses to post on the topic.

jl, I don't see it as internet hysteria as much as internet knowledge being passed around. It's been proven in civilian pistols that if you pull that trigger the wrong way, the pistol will not fire. And, conveniently, the military version apparently doesn't suffer that issue anymore (if it ever did).

Well, ok then. Facts still don't back up that it is a problem.

Here's a review of what is being done.

It doesn't appear to be a problem for the military and hopefully won't be a problem for voluntarily upgraded civ/LE pistols.

Thank you for that; very informative.

Yes, according to the video, the disconnect gives a "much different feeling trigger" and a "better trigger". "Better" in what way? "Better" in that it should finally be expected to ignite a round each time it's pulled....but no one will say or admit that.

Today I picked up a P320 subcompact kit that was gently used, on the shelf of a local shop. This evening, I removed the fire control unit from a P320 compact in the safe, and installed it in the subcompact.

None of my P320's exhibit any adverse issues. With this unit in the subcompact, I get two separate and distinct clicks when dry firing; a greater travel distance of the trigger, and greater time between them. In all my P320's, the tripping of the striker and the reset takes place close enough together that there's virtually nothing to separate them, and it's very hard to short stroke the pistol or to stop the trigger movement enough that it won't reset.

Not so with this subcompact kit, and I'm not sure why. About every fifth time cycling the slide dry firing, there's a very different sound, two distinct clicks, and when playing with the slide and trigger movement, it's very possible to either short stroke one direction or the other and not get a live press of the trigger on the subsequent dry fire. I'm not sure why this is so pronounced in the subcompact frame, but it is.
