M&P Failure - Striker Breakage

Well this morning I was doing my draw drills and dry firing before leaving the house as normal. Drew, aimed, pressed... No click. (oops, did I forget to rack the slide?) Rack slide, repeat... No click. Went to rack the slide again and had a hard time for a moment. Got it back and when I released it I noticed something fall out of the mag well.

After looking it up this morning it's not a real un-common issue.

Smith & Wesson wants me to sent the whole gun in, but seeing as it's been modified I don't think they'd cover it anyway.

ATEi is local to me and they've got spare I can pick up, thankfully.

The gun has approximately 3000 rounds, I think. And too many dry fires to count.

When the striker was modified as a part of whatever trigger work was done (as can be seen by the non standard profile on the small broken-off part of the striker), was a grinding wheel or other heat producing method used? Based on a casual comparison between the new striker I have in my hand and the photos, it looks like quite a bit of material was removed from the striker face. Just curious to know so I don't repeat anything that may have contributed to this failure mode.

From the coloration of the remaining striker bits it looks like there may have been an existing crack into which oil penetrated and then the final break occurred leaving the central light spot. It might just be a trick of the lighting though. Gotta love MIM.

Man don't show me this!!!!!! I'm kicking myself for not grabbing up some strikers when I had them in my cart a while ago. I really don't want to send my gun to S&W for something I can fix if his happens to me.

I have too have been wondering if the discoloration was oil penetration. Obviously, had I known of a crack I would have replaced the assembly.

To be transparent, this gun has ATEi's full trigger polish. Though, without further investigation I am not claiming in any sense that the polish job contributed to the failure.

The black strikers (as this one was) have been known for a higher failure rate than the silver colored strikers S&W is now using.

My suggestion;
Call S&W,wait 15 min and then tell C/S that the striker broke at 3,000 rnds.
Tell them you can easily replace it if they send you a new part.
No mention of $$$.
If you get a "NO",call back,speak to someone else.
If you are successful, you'll get a new design striker.

I called this morning and got a "you must send the pistol in".
I am actually on hold right now, calling back to see if I can get a different rep to send me one.

EDIT: Second S&W rep confirmed they have a total of ZERO in stock. Though, he was willing to add me to the list and have one shipped out to me when the do become available.

Make sure they send you the entire assembly. The little plastic retaining clip at the firing pin end of the striker changed from a two piece design to a one piece design a few years back and although both versions of the assembly are compatible with the older guns, the striker itself changed configuration and the two part retainer will NOT work with the new striker design.

Ask me how I know this....

I missed Doug in shop on my way out of town. Stopped at another shop I knew of and they had one in stock and replaced it free of charge. Got one of the silver ones in now.

The smith asked what happened to my trigger (full trigger job). Haha he said "that's dangerous"... please.

It's tapatalk's fault.

This is the older striker that was known for some breakages and that was part of the reason for the update in 2009.
