Question for those who shoot an M&P

[cody6.0]

Got a quick question for thoes of you who shoot the M&P especially in 40S&W.

I have roughly 200 rounds through mine and have noticed something about the ejected brass. There is a normal dimple from the striker then a small drag mark underneath like the striker was still out when the case was ejected.

Is this normal or should I say common?

I have never noticed anything like that on 9mm.

do you have a pic?  its mostly nothing, but you might want to check your breach face.

My M&P 40 has the same marks as well. Mine probably has only 500 rounds through it. It would have more if I could find any reloading components!

Thanks for the responses guys.

Just for kicks I looked at my Glock 21 and 22 cases and it does almost the same thing.

I'm going to forward this thread to a friend of mine.  He had an original M&P 40 that he sent back after 5000 rounds and S&W have actually spoken with him about some "Issues" with the guns.  I think he is on his 3rd M&P now.  He's trying to wear them out.

I have never noticed anything in my full size .40 M+P, 1 year old.

I am shooting this weekend and will take a closer look.

Jason, MY M&P 40 has always had that mark. The hotter the load the more pronounced it is. This is speaking from firing over 35,000 rounds through M&P 40s. (Another note:) I dry fire only after complete dis asembly to check function, have never broken a striker. On the forums I find those that dry fire a lot have broken strikers.  Steve

This is the info from my M&P Guru

Dry firing with snap caps is totally different than an occasional dry fire to check function.

Did the "guru" think this is an issue or not...doesn't seem to be.

IMHO, I don't think it is.
