Sig P320 un-commanded discharges

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.
