Sig P320 Striker Release During Function Check
Good Lord! In the comments there is this gem.
“I can replicate it with my 2 P320’s and every owner I know except one can replicate it.”

I don’t think so. As I understand the failure mode, the FCU (fire control unit) is allowing the striker to go forward without rotation of the sear. This modification will not fix that problem. Not, by the way, that’s the only problem with the Sig P320.
I have yet to see a complete, full, uncompromised and unbiased FMEA of the Sig P320.

The SIG P320 saga continues!
A SIG engineer filed a patent to fix the "unsafe" P320 in May. It seems they knew.

And Protraband updates us on his views.
Patent found here.
First up, Wyoming Gun Project does an update to answer some questions. This may or may not be related to one of the root causes of the failure, but this is a design problem either way.
Next, Protraband updates us on his recent findings concerning actions by the AF after the airmen was shot by laying his Sig P320 down on a table.
Next, Liberty Doll updates us on recent leaked documents from Sig lawyers. It does appear, after all, that there was a failure modes and effects analysis, and it isn’t good. Here are the source document(s).
Next, some clarifying (and bracing) information.
Finally, here is a list with linked documents that outlines some of the Sig P320 incidents. At this point, if you’re carrying a Sig P320 (especially IWB and Appendix carry), I don’t think you’re really thinking through this thing.
CHARLOTTE — Police said 71 guns were stolen while being moved from Bessemer City to Alaska and the safes they were locked in were later found busted open along a road in north Charlotte. One of the stolen guns has already been recovered from a convicted felon, but the gun owner says he’s praying the rest don’t end up in the wrong hands.
The gun owner hired movers to get his things from Bessemer City to Fairbanks, Alaska.
He said he doesn’t know how it happened.
Police found the empty safes on Vance Davis Drive earlier this month.
The safes had dozens of firearms in them.
“Oh, I was devastated,” said the victim who didn’t want to be identified.
The victim is a gun collector. The safes were supposed to be stored in public storage off West Arrowood Road until they could be sent to Alaska.
However, they were found dumped nearly 20 miles away along an industrial road.
“I tried to do everything right by the law,” he said. “I kept them all locked up all the time and then, this happens, so now, it’s pretty bad actually.”
The police report lists all 71 guns with an estimated worth of nearly $40,000.
The moving company told police they hired two movers from Craigslist.
Charlotte-Mecklenburg police officers pulled a car over in south Charlotte weeks after finding the emptied safes on the side of the road.
Sylvester Miller, a convicted felon, was in the car and officers said he had a gun.
The firearm was traced back to one of the stolen guns from those safes.
He’s now facing charges, but it’s not clear if he’s being investigated as a suspect in the theft.
That sounds awful. Seventy one guns. So much for Craigslist.
I’m not sure how I would do it if I had to move that many guns that far away. I’d like to hear suggestions in the comments.
Not mine, but his.
I’m surprised he isn’t carrying his .454 Casull wheel gun.
I don’t go into the bush where I live without being armed, much less in Alaska.
This is probably what’s happening to the P320. By the way, I don’t have a single pistol in my locker named Sig, and I don’t have a single pistol in my locker that has the tolerance issues between the slide and frame that the P320 does.
For those of you that say, “Well, he’s using a screw,” you’re missing the point. Watch the whole video before commenting or I’ll delete the comment. It’s getting hung on the sear if pre-tension has been applied as pointed out in the FBI report. Or there are manufacturing tolerance issues that could do the same thing.
Either way, this is a horrid, awful, terrible design. I would be ashamed to have my name on it. But not Sig, who has sued in court to block Washington’s police academy ban on P320s.
We had previously discussed the Sig P320 (with comments that ran at length), and there have been fatalities. There has now been another. Here you get a first-hand account of the primary means of discovery, and none of it involves the legacy media.
Next up, Ben Stoeger discusses this incident.
Then finally, James Reeves discusses how we got here with the Sig P320 being the sidearm of the DoD. Eh, I don’t know. I still think there was something afoul in the process.
As for his comparison with the Beretta and 1911, the Beretta was a fine pistol, and I’ll bet that in all of the 1911 failures (FTF and FTE) none of them were using Chip McCormick speed mags. I’ve never had any such failure with a 1911.
This is a great interview and one of the more interesting that I’ve had the pleasure to embed. I commend it to you.
If I wasn’t so jaded I wouldn’t hold the position that it’s not out of the realm of possibility that the DOJ harangued RBT into agreeing to retain all customer information (a change in policy) and then go after other manufacturers of this sort of device in court as a way of giving the next administration the ability to know who had them.
Cameron doesn’t seem to hold out much hope for RBT given the difference in design (lever versus cassette).
I’ve remarked before about the virtue and even necessity of controlled – managed – prescribed burns. It’s good for the environment. It’s good for other things too.
Adams says the location had a lot to do with the number of ticks swarming the deer carcass. The animal came from an area of Oklahoma with dense vegetation and no recent prescribed fire, which can create a perfect storm for ticks.
“This region tends to produce deer with heavier parasite loads,” Adams says. “But this was an extreme case, even for there.”

“Young fawns don’t move much. That’s their survival mechanism,” Adams says. “In areas that have lots of ticks, they will just cover the fawns. They’ll be all around their eyes, nose, and mouth. In those cases, ticks can actually kill fawns.”

Ongoing research from Craig Harper at the University of Tennessee is exploring how prescribed burning can impact tick populations. Early findings suggest that fire could be an effective tool for reducing ticks, in addition to its known benefits for habitat and forage.
