Pics would be REALLY helpful...

Barrel Hood/Ejection Port.

I might have missed it in the thread though I scanned it through. Are you using stock recoil springs. I know you said it was bone stock, so I assume the answer is yes.

Just wondering due to the location of the damage. Please let us know what SIG says if you choose to go the warranty route. It's worth a try.

It's also interesting to me, given the location of the damage, that SIG specifically says that using third party custom cut slides voids the warranty. You can, apparently, only use SIG custom cut slides to retain your warranty. They expressly state that on the site.

I know the OP DID NOT have a custom cut slide. My point is that the diagnosis that the lightening cuts might have been the reason for the damage seems acknowledged even by SIG. That is, if you don't do them right, you are asking for trouble.

I reckon Sig will be in touch with you shortly...

Issues with the barrel lug?

As noted above, clearly the failure is concentrated at lines originating at stress risers.

Major match? Minor load.

You said there was no barrel damage; you've had it out and separated from the slide for an inspection? How were the lugs? What other marks are visible on the barrel, and chamber exterior?

The stovepipe is normally an underpowered round.

The stovepipe could also have been caused by the problem that was developing (most likely was).

The stovepipe was caused by the failure. It happened multiple times as I was trying to shoot the stage. Didn't realize there was a failure until it happened a bunch of times. I'd clear the stovepipe and it would load a round, I'd fire and got another stovepipe. I originally thought the mag went bad, so I kept going. I actually have a video of the whole thing until I was stopped.

This exact same thing just happened to me at an USPSA match. Luckily I had a backup gun, but my match was done on the first stage due to everything the OP described. I called Sig during the lunch break and they emailed me a shipping label and gave me a RMA number. 3 weeks warranty fix was the guesstimate. Good thing I have 2 back up pistols since nationals is soon, but this was disappointing and kills confidence/trust.

How many rounds do you think you’ve shot in this gun ?

Meh, this stuff happens when you actually shoot a gun.

This is a department-owned S&W M&P 40 from work:



The gun still functioned, but was having failures to eject. It had around 5,000 rounds through it and was on its second recoil spring. 95% of the rounds shot through it were Federal American Eagle or Winchester white-box 180gr FMJ with the other 5% being Federal Hydra-Shok and HST duty ammo.

The gun went back to S&W and they sent it back with a new slide. It's been in service ever since.

Just call SIG and have them make it right.
