Light Strike/ Misfire Problem

[alistair]

So I have a with my M&P Shield what do I do?

The last few times I've taken my Shield to the range I've noticed that there has been quite a few misfires or nonfiring bullets. I thought that it might have been due to a bad lot of primers so I ran a new lot of reloads and went back to the range.
The picture shows two cases from bullets that fired and two bullets that did not fire. The firing pin obviously is hitting the bullets low.
Is this a overall gun problem and it should be sent back to factory, or is it just a firing pin problem and the pin should be replaced?

Trade for a glock.

First of all the 2 that did ignite look like the firing pin pierced the primer. Also on those the primers look like they are showing over pressure.

So my guess is you have a bad firing pin. If the primers did rupture then the escaping the gasses probably hurt your firing pin. This could have bent your pin or made it abnormal causing the light strikes and off center strikes.

Look at the tip of the firing pin and see if it is damaged. Then check the travel of the firing pin to see if it moves freely. It might just need a good cleaning.

If you can't figure it out, send it back to S&W. They will make it right.

See above.

If not. Reloads? Seat your primers deeper. The fp is probably pushing the primer in, and not getting a good hit on it.

Check your fp for issues. Measure it. Clean the fp channel. Check fp spring.

If all is ok then see (freddy) above. Last thing you want in a carry gun is to be questioning it.......

Thye look like good hits. Did you try an entire different lot of primers? A different brand?

What is your load data?
