Called S&W customer service on the 15th. Explained my situation to the guy on the phone (Broken striker assembly). I asked if they could just ship a new assembly as opposed to me having to send the gun in which they had no problem doing. Got the new striker assembly today. I have heard S&W has great customer service and this dealing backed that up. 5 days from phone call to part in my hand is a really good turn around time.
I immediately noticed that the new striker assembly did not look exactly like the old one. The new one appears to be all stainless steel where as the old was not. I did a bit of research when the problem first occurred and from what I gathered it was a fairly common problem with the early M&P's. It makes sense that they would change to a completely stainless striker assembly.
Either way, the gun is fixed, tested and up for sale/trade on my local gun forum.
