Ammo or fireing pin issue?

[CJD3]

A friend brought over his new M&P shield-9 mm

The only shells he had were Remington "range" JHP so there is nothing to compare to.

My issue is the primers. I looks as if the fireing pin is still seated in the base of the shell as it's being ejected.
You can see the "ripple effect" in the pictures. He will be trying other ammo makers but my concern was if the fireing pin was the problem.

Any one see this before or have some ideas?

Disassemble and make sure nothings in the pin area and spring... inspect for burs in the firing pin hole...

Looks to me like the firing pin is seating to damn far and getting stuck in those primers.

Either that pin is to long or the factory lube isn't slick enough to allow the pin to return fast enough to get out of the way before it's ejected. I would break it down and wipe everything down and check for debris. Lube everything really good and try it again.

A sincere thank you to the very few that responded.

I didn't see it until now since I haven't been on much.

This is normal with the Shield. A deep, kinda misshaped compared to others, firing pin strike is the norm. Bet they had "light strike" issues with testing and solved it by going overboard with firing pin length.

Thank you for responding Charles. I value your input as well.

How does the breech face look? Any cratering around the firing pin hole? Sounds like it's normal so that's good.

I have never heard complaints directly from a shield owner but S&W did have a large rebate offer for several months last spring(?) which might indicate off and on problems that did not warrant a huge recall.
I have also noticed S&W recalling T/C high power rifles, supposedly all 4 models. Could very well be poor workmanship, like Marlins made by Remington. Ruger has a big recall on the latest 22 aut
It seems like the gun companies built new factories in other states and hired new employees lacking skills.

My taurus mil pro 45 gouges the shit out of primers. Some of them have a huge gouge from center hole to the edge of the primer. Shit goes bang every time and thats all i care about.

All the m&p handguns do that including my shield.
Spokane police carry the m&p. I was talking with a crime scene tech awhile back and he said its easy to ID officers brass vs suspect brass based on the primer strikes.

Thank you for the added responses.
I will pass them on as well.
