I broke my M&P!

[fastk9dad]

I have never seen a failure like this before but I managed to do it...

Doing some drills today and it went something like this: bang, bang, bang, click, tap, rack, click, tap, rack, click, *swear*, unload, field strip, well there's my problem!

Apparently I managed to break the trigger bar loop that releases the sear. It was leaning to the side and hanging on by a thread, I touched it with my knife and it broke right off. I'm guessing it was either fatigue or a defect in the metal, there is less than 4k through the gun so it's pretty bizarre. I already have a new part on order, along with springs for the 5k replacement and will just freshen it up early. I'll also be calling S&W on Monday and have them send me out a replacement part that I'll keep as a spare.


Now my SIG P220CED is getting some time on the belt.

I've never heard of an M&P failing in that way. Some "wear" is normal, but never heard of a breakage. My M&P 9c has operated flawlessly, but this will be something I'll surely pay attention to. Anyone else have this happen?

To the OP: Updated us on what Smith and Wesson says/does about this.

Yes please do because I am thinking seriously about purchasing one.

[fastk9dad]

I wouldn't hesitate purchasing one, I have never seen this failure before and can't find anyone reporting they had the same issue. Lots of guys tweak on the loop for better sear engagement so I'd say it's normally a stout piece. I'm guessing there was a defect in the metal that just finally gave way today. I have a full size with more rounds though it than this compact and zero issues and all the internals are the same between guns.

Wow that's weird but after all the gun is a machine of sorts and a machine can break down and have even the most unusual parts can be the problem.

I don't think it's been an issue for M&P's. so, likely just one of those flukes where there was a defect in the part.

I certainly wouldn't let it discourage me from getting one. I have a full size and a Shield both in 9mm and they have been very robust and 100%. After owning Glock for 12 years, I sold it (to justify to the wife for getting the M&P) and I sure haven't looked back with any regrets. And I really digged that Glock.

I purchased the full size m&p40 a few yrs ago.One day i went to shoot it and the bullet jammed between mag and chamber,a couple of times..I was bummed out.It was just the spring in one of the mags.

"Click, tap, rack, click swear"

Ok, THAT was funny! Hope you get it fixed soon, thanks for the laugh.

Wow! Even with a very reliable pistol like the M&P there is reason to carry a backup gun. Lesson noted.

Huh. I've been watching the M&P line since they came out, this is the first I've heard of that. I guess it was a freak thing. I'm 100% confident S&W will make it right, but I'm curious to hear if they offer any information about others experiencing this, IE a bad batch or something.

Contact S&W, they should replace it at no charge. Hard to tell why it failed. I would guess it had stress fractures that were missed during assembly. If it's built by man, at some point it's going to fail.

fastk9dad - have you been taking lessons from Rollo???

BTW, I had to look twice to make sure the thread wasn't started by Rollo!

I'll keep everyone updated with any info they give me. I have no doubt they will make it right, they sent me the updated slide lock assembly when I asked for it so I'm sure with a real failure they won't hesitate. The loop snapped right at the base of the trigger bar where the right angle is joining it to the rest of the bar so I bet there was some defect there. The only reason I already ordered a part is so I have one here by next weekend, I've got quals coming up soon and this is by backup so I want to put some new rounds down range with it and not be w/o it for two weeks. It's only a 10 minute job to change so it's no big deal. I will offer to send them the old part back and maybe after I qualify I'll let them look the whole gun over, but I see nothing wrong with the rest of it.

Here is the broken loop...

I guess I've been reading too many of his posts.

Did Rollo touch your gun at anytime
