If the trigger is being inadvertently being pressed, that may help mitigate an uncommanded firing.

If the sear is letting go, you will try to fire a gun with a dead trigger. If the firing pin safety also fails, the gun will fire. With no interaction with the trigger.

That a real problem.

Is it the current catastrophe of the day? Yes. Are a lot of people piling on Sig? Yes. Has it been proven to happen. No. Are there numerous videos and statements from people showing them going off in holsters, yeah. There kinda are. Would I carry one? No.

There’s a lot of guns out there that don’t have quite a few instances of apparently firing un commanded.

Yea I think as already mentioned my answer would be just to swap weapons. I know you have a P-series on deck but other good striker options are:

PDP
Glock
CZ P-10
S&W M&P 2.0

Are un-commanded discharges only happening with the 9mm 320? Have any been reported with the 320 Xten? I have both and don't carry either one. The 320 went back for the voluntary upgrade in 2017. I should be okay as long as I don't holster them.

My Walther PPQ 45 fails this and from what I'm reading on the internet, it's just the way it is. As long as the sear is engaging the stiker, ot doesn't matter how little or how much the slide is pulled back, pulling the trigger releases the striker and the firing pin pokes out of the breechface.

I watched it with the barrel out. I verified it with the barrel in by holding the gun vertically with a pencil down the barrel eraser end first. I could hold the slide back 1/32" to the point before where the sear doesn't touch the striker and every time I pulled the trigger, the pencil jumped because it was getting hit by the firing pin.

This seems like the gun could be fire out of battery.

I checked my PPS and it has a disconnector and the trigger is dead when the slide is pulled back.

That's kinda unnerving. I know very little about Walthers...does the PPQ even have a disconnector? If it does, and it's behaving like that, I'd say it's not working. It could be that the design doesn't have one, though.

The original pre-upgrade P320 did not have a disconnector. It was added to the design as part of the upgrade, and IMO the out of battery protection that it provides is worth the effort of getting the upgrade done, even without considering the drop safety stuff.

Walther says there’s a disconnector, but it’s clearly not the kind Sig uses. Today, I checked my dad’s new P365 X Macro and it works exactly as you described: dead trigger unless it’s in battery.

A little more reading online says the Walther’s striker block is supposed to prevent out of battery firing. It makes sense that if the slide is back due to being out of battery, then the tab on the trigger bar shouldn’t disengage the striker block when the trigger is pulled. The sear is independent of the position of the slide and will thus still drop, but the striker block is dependent on the slide’s position and should stop the striker if the slide is out of battery and the trigger is pulled.

Owned, carried, shot at least 4 PPQ's for many years. Never heard of an unintentional discharge with one (outside of ND's of course).

The Walther PPQ (like the earlier P99 and later PDP) most certainly has an out-of-battery disconnector. It’s a protruding tab on the trigger bar that fits into a groove in the slide. When the slide is out of battery, it rides this protrusion and forces the trigger bar down, much like a classic P-Series (P220, P226, etc.) or a Glock.

I wanted to get a P320, but don’t I think I will now. Lack of confidence is hard to get past and I have no need for a pistol that I can’t trust.

I see that now: both the tab and where it rides on the slide. I see where the piece on the back of the trigger bar doesn't move the part that allows the sear to drop if the trigger bar is pushed down.

It doesn't work on my gun. That valley the tab sits that allows the trigger bar to be high enough to work is too long or in the wrong place. With the slide out of battery, that valley is behind the tab and the tab is pushed down. That'd be great, except when you pull the trigger, the tab moves back into the valley, the trigger bar is no longer pushed down, the part under the sear gets moved, the sear drops, and the striker is released. This could probably be fixed if the valley were a bit shorter and a little further back towards the rear of the slide or if the valley were a bit shorter and the tab was further forward on the trigger bar.

I apologize for the thread derailment, I didn't realize where my post was going to go, and I should have started a new thread.
