what does a normal M&P 9mm striker look like

[HP1]

I have been shooting this gun since 2010 and have never had a problem but noticed over last few months I am having a few fail to fires and now I am having almost every shot resulting in a fail to fire. There are Dents left in the primers and ALL will fire when put back in magazine and fired again. The ammo is the same 3 types of ammo I have been using for years and is not the problem. When I dry fire the striker does not sound as crisp either. I removed the striker and ensured the channel was clear and the striker was generally clean.

Is it normal for the striker tip to be bulged? I don't mean the very tip I mean the part of the tip that guides the striker in the channel. Seems to me the bulge would cause friction rubbing as indicated by the shiny rub marks. I am sure I can send the gun back to have checked out and I will call on monday it is just I hate to not have this gun over the coming month. I would rather just file clean the edges of the striker if that is the root problem. Not sure if it is bulged from use or Design so I wanted to ask. Honestly if that is not the problem I don't know what is becuase it looks fine other wise except is does not sound crisp anymore.

If you want to avoid sending in the gun, just put in a new striker assembly, which is available at reasonable cost from several sources, including Brpwnells. It is considered a wear part to replace if you shoot several tens of thousands of shots. Those and trigger springs appear to be the most frequent wear parts replaced on M&Ps. Ironically, the stock recoil assemblies last much longer, even though some shooters replace them quickly.

A couple of years ago there were reports of strikers breaking so I called S&W customer service. I asked a few questions about the striker in my gun. Turns out there was an upgraded version and he said he would send me one free. When I told him my wife's gun was the same age he said he would send two. Can't beat that! So you might want to give them a call Monday and discuss your problem. If your gun is going on six years old it might have a tired striker spring.

I don't have a striker to compare, but I suspect the striker marking/contour is not the cause of the light strikes.

If the contour of the striker was the cause, you'd have had more light strikes initially, and less as the striker wore to better fit the striker bore...which is the opposite of what you're seeing.

The striker safety bore can accumulate primer shavings and retard movement of the striker safety plunger which can impede striker movement. Did you check for this, when you pulled the striker?

If remember correctly mines are all shinny metal, your looks black could be an old version I don't know.

That striker is the old design (the black color), S&W changed the design because the striker was breaking. I called them and told them that I had a black striker and they sent me a new one. This was a few years back so I don't know if they're still doing this but it's worth a phone call.

Very helpful replies. After calling customer support I explained my situation and they are going to send a new striker when they come in stock. So thankful they let me continue to use this my primary over the holidays.


I removed my striker sleeve as suggested and removed quite a lot of brass shavings. When I put the gun back together and used a stryker from my shield which was the newer style as a test and it sounds very crisp again as well as the spring seems much firmer. I need a trip to range to confirm but I am sure its 100%.

I made a mistake a while back by allowing oil to get on/in my stryker during a sloppy cleaning which I believe encouraged debris to wick up behind the sleeve with would result in a tighter fit than it should be.

Now I know where to avoid oil entry into.

Thankyou again for the help.

Contrary to how I clean/oil my other pistols, I followed the owners manual on my M&P 45 by oiling only where they said.
