Found another design defect with the P365.
Anyone here ever try to clear the chamber with a Speer Gold Dot or Hornaday Critical Defense in the chamber. The following pic should be quite familiar to you.



The problem is that Sig Engineering decided to design this pistol without any slide overrun. The problem with this approach is that if the bullet doesn't clear the barrel before the cartridge hits the ejector you get this type of jam. Granted Sig did provide a clearance cut in the barrel but it's designed to work with 115 grain round nose. It won't work with a 147 grain flying ash tray. BTW, testing last weekend indicates that these pistols are regulated for 147 grain loads.

Note to Sig Sauer. First, your engineering sucks. There is no excuse at all for the horrible trigger and now a complete lack of slide overrun. Ruger doesn't have to cut clearances in the barrel of the LC9S because they designed the pistol with enough overrun the bullet is clear of the chamber before the cartridge hist the ejector. In addition the trigger on the LC9S is VASTLY superior than the cludge on the P365. If anyone asks me if they should get a P365 I will tell them to get a Ruger Max 9 and I will then recite all the faults of the P365.


I've stopped counting.

I have never had this problem, removed lots of gold dots, hst, critical duty, and lots of other brands ranging from 115-147gr. Not sure what the issue is with your pistol. Have used 2 365s and 2 265xls without experiencing anything like the photo.

I have the same response as tgmr05. I own the following P365's:

3 Standard P365's with about 7K rounds total through them.

3 P365XLs with about 5K rounds total through them.

1 P365 .380 with about 500 rounds through it.

1 P365 Macro with about 600 rounds through it.

Defense ammo has been Federal HST, Speer Gold Dot, Federal Hydrashok, Federal 9BPLE, Hornady Critical Defense, Hornady XTP, Remington JHP, Remington Golden Sabers, and Winchester Silvertips.

I have never had the issue that the OP has. Actually I've never had a failure of any kind with these pistols and 1 of my standard P365's is an early gun with a 3 digit s/n (ok there are bunch of zero's in front of the 3 digits).

I only run Gold Dot's through mine, as that's what we are issued. Never had this problem.

As above, never had this problem.

If, and this is a big if, it legitimately won’t run that ammo or apparently eject it either he would call Sig and get a return label. Alas that’s not what he did. He makes a malfunction and then photographs it. I could reenact that picture with any flat nosed round in any gun.

I’ve shot a lot of Critical Duty 135gr +p along with Federal HST, Winchester Ranger and Speer Gold Dot 147gr through the 2 P365s and the P365XL I have owned without issue.

I carry Gold Dots in my P365, never had an issue ejecting them when I clear for cleaning.

I have also never seen a Speer factory loaded Gold Dot with a brass case; mine have all been nickel.

That round also looks really long. Is it factory Speer?

Yep, looks way too long.

It appears to be User error. Maybe your reloading is the problem. Mine has run like a scalded dog.

But don’t get me going on their slide drilling and tapping for 6-40 screws.

No problem with either of my 365s using factory ammo from Speer. Maybe it is your ammo?

Looks to me like it'll kick an empty shell out just fine.

I own 2 Sig P365's. One was manufactured during the first year of production, the second is a P365X that I bought last year. They both run great. I've never had this problem in my P365's, even after running over 2000 rounds of Gold Dot, HST's, and specialty rounds (Underwood in them. This cartridge's OAL dimension looks strange. Before blaming the gun, I'd definitely want to check the ammo.

No issue with 147 Gold Dots in my p365. The p365 had it's teething problems, but it seems like they're pretty well sorted now.

"Odd," said Arthur, "I thought you said it was a democracy."
"I did," said Ford, "it is."
"So," said Arthur, hoping he wasn't sounding ridiculously obtuse, "why don't the people get rid of the lizards?"
"It honestly doesn't occur to them. They've all got the vote, so they all pretty much assume that the government they've voted in more or less approximates the government they want."
"You mean they actually vote for the lizards."
"Oh yes," said Ford with a shrug, "of course."
"But," said Arthur, going for the big one again, "why?"
"Because if they didn't vote for a lizard, then the wrong lizard might get in."

For what it's worth, the Speer Gold Dots in .327 Fed. Mag. are in brass cases. Different round/caliber I know.
I agree on the length of that round. I wonder what it mic'd at?

The overall length of that cartridge is 1.130 inch, measured with Mititoyo digital calipers that were properly zeroed. So, it's not "long". I practice with the same load I carry and this is a practice round. Note the position of the slide, there is 0.020 inch more slide travel available than the position shown in the jam picture. On the Ruger there is about 1/4 inch more slide travel available. Note I am basing these comparisons on the relation of the breech face to the magazine rear with the slides fully retracted. On the P365 the breech face is about 1/32 inch behind the rear face of the magazine. On the Ruger it eyeballs at 1/4 inch. Frankly I find it rather surprising that the P365 is actually reliable at a timing this close. I suspect that long term these will prove to be sensitive to magazine springs.

Sum it all up and I regret this purchase. I should not have listened to all the fan boy postings. This pistol has the worst trigger of any handgun I've owned or even handled. Then there is the failure to clear a chambered self defense round. Yeah, I know, all you are doing is clearing the pistol so it doesn't matter in terms of defense. Take a look at that picture, do you want to have to clear that mess once a day? At some point that primer might get tapped and if it happens it's going to hurt a LOT.

Nope, doesn’t look at all familiar. I carry Gold Dots in mine and have to clear them to shoot target ammo. Never had a single issue. I’ll carry 124 or 147; I avoid 115.

Not sure what your method of clearing is, so I can’t provide any feedback there. But it could be an issue with your method, could be an issue with your particular pistol, could be an issue with that particular lot of ammo. But it doesn’t seem to be a widespread issue.
