[quote name='vzontini']Wow, one thread with 3 totally different firing pin/striker failure descriptions.
Are these parts cast, MIM, machined from barstock?
I'm betting against machined from barstock, due to cost. If I had to guess I'd say MIM from the pictures. MIM can produce good parts. Parts not holding up points to a process issue and obviously a QA/QC issue if they are making it into shipping guns.
It's machined, and a roughly i might add. I spoke with a tech at S&W today, there is a newer revision of the part. I didn't bother to ask for specifics, i'll post a picture of the new one when it gets here. IMO the CNC programing for the part was what was causing the problem, the machining process can create huge metal fatigue producing failures like the one I had. If this part were machined from 4140 CroMo or 416 stainless the parts may have been fine, but our M&P strikers are some sort of tool steel that is not a free machining steel and that makes all the difference in the world. I'm sure S&W will work it out.
The Tech I spoke with today mentioned getting to try an M&P out last wekend, he seemed really impressed with the work on action performed by Dan Burwell.[/quote]
I received the striker a few days agao and think i misunderstood the Tech and that the part is the same as the one that came with the gun, He mentioned that it would be marked with a 9, it came in a plastic bag marked 9mm. :roll:
just want to un-confuse the situation
