Brand new M&P 9mm Shield PC I bought yesterday and shot it today.
Same problem as lots of others are dealing with the slide locking all the way back. Some target ammo ran great without any problems, another had constant problems every couple rounds.
Cleaned it and oiled it good before firing it. When I rack the slide by hand I can feel the parts that are hanging up. Question is, do I just send it back to S&W now or run a couple hundred good rounds thru it to break it in more first??
Thanks!!
