Sig P320 un-commanded discharges

[PriestTheRunner]

Additionally, Dallas PD has banned the 320, among other law enforcement agencies.

Washington State Criminal Justice Training Commission, the Milwaukee Police Department, the Dallas Police Department, the SEPTA transit police in Philadelphia, and a host of other agencies in Alabama, Connecticut, Florida, Texas, Washington and Wisconsin, with the United States Air Force Global Strike Command (AFGSC) being the latest after this week’s tragedy.

When pressed for details by The Firearm Blog regarding the issue with the P320, Debra Webb, a public information officer with the Dallas PD, said the following: “The department was notified that Sig Sauer identified a defect in the P320 handgun that could cause the weapon system to go off when dropped. Please check with Sig Sauer for more information about the defect.”

I was hesitant to post this when I first saw it, as I do have an issue with him using a screw in the trigger, but in full length youtube video at the beginning, he shows that what he is trying to measure is that with the trigger barely touched but not pulled all the way, the play in the slide causes the P320 an uncommanded discharge. But I think anyone who has a Sig P320 should watch and make their own decision, but as noted above in PriestTheRunner's post, some ranges are banning them.

For those of you that follow Hickok45 he's posted his take on his youtube channel.

Short answer: he said he wouldn't trust it with a round in the chamber.

Kinda like how Sig quietly updated the user manual to state to keep the chamber empty until ready to shoot.

(Revision 11) explicitly states in bold: “CARRY YOUR PISTOL WITHOUT A ROUND IN THE CHAMBER”

The Sig forums noticed this in April 2025, along with Reddit. The 365 Manual doesn't have the same bolded emphasis either.

Wisconsin Gun Project has a take on the issue: some screenshots below

If I owned a gun, I would only have guns with a side mounted safety carried with a bullet in the chamber. I have seen a video I will never forget of a poor jeweler trying to rack the slide while he is being repeatedly hit by bullets from one or more robbers.

I am unfamiliar with this gun. Can you lock the trigger with a safety?

I’ve noticed a lot of YouTube activity about this gun, it seems to be growing and not going away. So it must be really serious. I noticed a Houston police officer is suing SIG for being injured by this gun.

I don't own a 320, but with all the hoopla from the Air Force and the public.....and SIG basically doubling down on calling it user error in every case, I can say that I will never own one.

The Air Force has arrested an airman in connection with the July 20 death of another airman, which involved a Sig Sauer M18 and led the service to suspend the use of the pistol following the incident.

In a Friday statement, a Department of the Air Force spokesperson said that the unidentified arrested person is accused of making a false official statement, obstruction of justice and involuntary manslaughter.

Another lesson in why people should let an investigation run its course before jumping on a bandwagon.

Another lesson in why people should let an investigation run its course before jumping on a bandwagon.

True. But in this incident the Air Force publicly announced they had suspended the use of the firearm. Which cascaded into:

• Multiple gun ranges banning the P320

• Multiple Police departments have banned the P320

• Houston Police department banned the P320 citing a lawsuit from an injured officer (claiming mis-fire)

It did not help Sig that there has been other complaints of uncommanded discharges on the P320 platform. The perception is and has been for a while, that this weapon has issues. I do not see how the P320 will be trusted as a duty weapon for real or perceived legal liabilities.

But I have to say, that with so many P320/M17/M18 weapons in use by Military, Federal LEOs, and other LEO's, if it was a problem with the weapon, you would think there would be several more incidents.

DPS has been using the P320 and I haven’t heard one complaint from them.

Maybe DPS has better trigger finger discipline training?
