Brand new M&P sport here, I noticed after chambering a round and ejecting it unspent, there will be a small dimple in the primer from the firing pin. I can reproduce this every time I chamber a round. It appears that the forward motion of the bolt group throws the firing pin at the round when the bolt suddenly stops.
Is this something to be concerned about?
