UPDATE FEB 2:
This gun got turned around by smith in less than 3 weeks start to finish. About 18 or so days i think from the first time I dropped it at fedex to send back. Replaced the whole slide insert but everything else checked out. They also sent back more recall paperwork indicating it had been checked for the recall, even though this gun had already had the recall completed. Not sure if it was turned around so quick due to extra recall folks on hand to look at the shields? But in any case, shes back with me. Ill take it back for a spin this week, but to be honest I lack the confidence to carry this gun like my life depends on it. Switched to a CZ for those duties. Again, this very well may have been a fluke one off chance occurrence, but still....

Hello everyone, posting this as a PSA for you all to check your guns to make sure this is not just some random one-off issue I have the pleasure of experiencing. This is my shield EZ performance center in 9mm, purchased last year around June. Gun has less than 500 rounds through it. All factory ammo, 99% of that not even +P loads, as if it should matter. I usually fire about a mag or two each range trip to ensure the gun is functioning well, as this is my daily carry. The gun went back to smith in November due to the most recent recall campaign on the shield EZs (this series seems to be quite fond of recalls), and it came back to me with no parts replaced, assuming no faults found.

This past Thursday, I put two mags through it at the range to function check and all seemed to be ok. On Saturday, I go to chamber a round before putting it in my belt and I notice the loaded chamber indicator is sticking way out of the gun. I unload it and I see what you see in the pics below. A catastrophic failure of the breech face into a few pieces. Scary stuff. Not sure if either a) that could have allowed the firing pin to set a round off as I racked it or b) it could have failed inside my pants (appendix carry.) Glad I didn't have to find out for real.

I contacted smith this morning and they really didnt seem too interested in the circumstances of the failure, and said sorry, it will be checked via the normal warranty process and you'll get the gun back in 8-12 weeks. Kind of disheartening especially since this is the second gun that they will now have from me, after currently also having my 617 (for its second trip back for warranty work).

This very well is just a one-off freak issue, but considering the track record of EZ shield recalls Id say its worth a very thorough check for cracks if you own one of these. This gun never saw any ammo or firing conditions out of the norm besides basic range proficiency use.

I'm no expert, but I believe that's broken. From my experience sending cracked stuff to S&W, they will perform a metallurgy test on that breech face/slide to determine if it was indeed a manufacturing error, and then if it was indeed such an error, you'll be offered a new pistol. Took about two months from shipping to new pistol in hand for me, but that was pre-COVID . . .

Good Luck!

Oh interesting. Thats what happened with yours? I would have figured at most it would be a complete slide replacement, not an entirely new gun/background check and so forth. That happened to you?

No. Mine was a 637 revolver with a cracked frame under the forcing cone. I was just detailing what they did to determine if it was their fault or not. If it was mine, I'd be nervous about other damage to the frame, since you really have no idea how many times you fired it broken . . .

Yes true. I would think that firing even one round in that condition would have been a spectacular failure of the gun, but who knows. Im quite diligent with checking over the gun each use. But to be honest now Im going to be paranoid about carrying this thing after it comes back.
 
That’s just plain bad luck. That’s all. The slide and breech face are not MIM. I bet this anomaly is a less than 1/1-million metallurgical failure.

They can make you a new gun with your same serial number and ship it directly to you as a repair. They will destroy the old one. Just takes some time for them to jump through paperwork hoops and custom serialization.

They will carefully document the failure for their QC history and protocols.

Stuff happens. Sorry. You’ll get a new gun.

Have you ever seen one in person? It's as MIM as I've ever seen.
 
I hope you have the box for the ammo last used that caused this major breech face part failure. It’s possible you got a double/overfilled charge in one of the rounds you fired.
If no problem is found by S&W from a parts/metallurgy standpoint, you may be looking to the ammo manufacturer for a monetary settlement.
I look forward to some of our expert pistol smiths that frequent this forum to weigh in. It should make for an even more interesting discussion.
Great pictures by the way !
Glad you weren’t injured !!!!

Be SAFE and Shoot Often!

Oh gosh just some basic factory stuff, either UMC or norma range and training i think I have the most of. Nothing about my most recent range trip felt off, or induced any obvious failure. After using some basic ammo, I loaded my carry mag of defensive ammo back in and went home. It wasn't until loading a round in the chamber two days later did it crack while sending the slide home. Perhaps it could have been a hairline crack slowly growing over time and that one instance was the straw that broke the camels back?
 
I guess we now know the round limit of a cast breech block. Kind of MIM-sical wouldn't you say:D

I would say its cast garbage myself, thank God Smith and Wesson do not build aircraft, its clear they have failed "structures 101" again, and again, and again.. to the OP, count yourself fortunate to get a new slide or have it returned to you in functional condition...

I'm sure it was that 1 +P plus, plus plus ammo you loaded up in your basement?? just being facetious here, but do be absolutely clear about every round you ever put through that thing, and I pray you didn't shoot anybody's reload, or that will all be on you...

Castings are far more prone to failure than traditional forgings, which in the past all quality firearms were forged. Yes I know, castings can be very precise and very strong, but have a look at that grain structure, its extremely porous, I find it astounding that Smith and Wesson would consider that good to go for the breach of that weapon, but they do!
