It will be more difficult to see if it's a hard primer/light strike after you've pulled the trigger the second time and fired the round. The real inspection would be to wait about 30 seconds after the failure to fire, eject your magazine, and carefully eject the unfired round and see what the primer strike looks like, compared to ones that have fired the first time. I'll bet you will see that the primer is dimpled less than the others.

Looking at your photos magnified, I see another little "divot" on each round, to the side of the main primer dimple. Wonder what's causing that? Is there something on the slide face causing that? Or is it a secondary bounce or something from the firing pin after the round fires? Would be interesting to see if that second little mark appears on one of the rounds that didn't fire with a single firing pin hit.

Also, some of the photos show the firing pin dimple pretty much in the center of the primer, on some of them there's a definite offset from center. Couple an off-center hit with a harder primer, and there might not be enough force for the primer cup to strike the internal anvil to ignite it.

Yes, I noticed that some are off center and noted the presence of that tiny "divot". I am fairly new to Sig, so I did not think that is something too unusual. Hmm.

I wonder if this being a factory .40 Sig with a .357 barrel has anything to do with that? I noticed that the barrel in e2 upper appears a little loose, but it seems to be that way by design? Maybe the slight wiggle of the barrel during the cycling produces an off center strike?

I don't know.

I don't know.

That is quite common with almost any semi-auto handgun. It is firing pin "drag", caused by the case starting the ejection process before the firing pin has time to fully retract. Remember, the slide is moving backwards rather violently. Simple inertia will keep the firing pin forward for longer than it would if the slide was stationary.

In other words, it's perfectly normal.

I have to correct myself on saying that the barrel "appears loose". I just did a side by side comparison with an legacy upper, and the wiggle is the same. They literally have the same feel and look in the way that the barrel moves and is seated.

I just ordered some Speer gold dot jhp from Ammunition Depot. I plan on running another 150 rds of this stuff over the weekend to see if I can get any failure to fire reproduced. I'll report back on that.

Side note to all 357 Sig shooters, check out the prices on gold dots from ammunition depot

$22.97 for box of 50! That's a pretty darn good deal for premium ammo!

Another side note , I suppose this topic question has been addressed....I did not limp wrist the Sig. I did nothing wrong...I am ALWAYS right, except when I think that I'm wrong.

My EDC is a P239 in 357 Sig and by the nightstand is a P226 in 357 Sig. My experience with 'range' ammo in that caliber is not very good, lots of fail to fire. Run 100 or 200 rounds of premium ammo through the gun to get a good feel for its performance.

Side note - Sig 'range' ammo in 357 Sig is the most reliable I've found. I've had lots of problems with off-shore range ammo in that caliber.

One of you .357Sig guys needs this ammo.

I just ordered more ammo for this weekend. Could I perhaps offer a gentlemen trade? I have holsters, .40 barrel for p229, H&K usp40c mag..

I have went to just .45acp and 9mm. I no longer have .40's and .357sigs. I hope someone can give my ammo a good home. I think it is priced cheaper than anything I have seen for sale thus far.

Indeed it is! If I had the funds, I'd grab it in a jiffy.

From someone notorious for limp wristing, my SIGs always fire, always. What I get when I do limp wrist it is a failure to eject the round. Then I have to clear the jam and start again, but the initial shot always goes off. I had this happen mostly when my p226 was new, like yours it is a DA/SA model. It also happens frequently with my dad's Kimber Ultra Carry 2 which is very stiff.

Yea, I will conclude that I indeed did not limp wrist my Sig.

I ran 52 additional rounds today of Speer gold dot jhp through it, wanted to run more but ran out of time...

All fired flawlessly. I randomly picked up 5 casings and the strikes look good, pretty strong.

I managed to dig two bullets out of the railroad tie backstop and of course, they are pretty much flattened.

Had nice time and such...

NJSP are having an issue too but it looks like it might be their cheap range ammo. https://www.thetruthaboutguns.com/2017/ ... ing-p229s/

That is interesting. So NJSP is having failures with the new Sig models (large extractor), then Sig sends them new guns (with legacy extractors) and they continue to have failures?

Every gun company has few bad apples here and there, but Sig is well known for reliability. To have two different models of their p229, which is popular in LE community, have so many failures just seems strange to me.

Today marked roughly 652 rds that I've fired through mine, and aside from two instances where I had failure to fire using elite performance ammunition I have not had any issues whatsoever.

It is boringly reliable. I even tried to limp wrist it today using my non dominant hand and it just kept going.

Couldn't be their ammo?
