For you M&P guys, this may help if it applies.
I got this from someone in the S&W food chain, good source.

As far as the gun goes I ain’t never heard of pin walking out of the gun. That is the benefit of roll pins. I heard of people mistaking the locking block pin as walking instead of realizing that the locking block pin protrudes slightly out of the right side of the frame acting as an over travel stop for the take down lever.
Thanks Mark!
This is indeed what I thought was happening until Mr. Burwell pointed out the above to me. Most people do think it’s walking out and drive it back in mistakenly.
Mark5pt56 I believe that should be the left side of the frame, if your looking at the pistol from the rear.

Ok, take note. I don’t have one anyhow.---------I’ll get one up on M4arc—not yet----baaah
I’m selling my .40 M&P if you want one cheap! 
I appreciate it, but I’m poor right now. I’m not looking for one anyhow. I am saving for M4arc’s G19-:eek:
Give in to the dark side…
Trying to rub your evilness onto someone else now I see…
I can remember a few months back when M4arc was the voice of dissention towards M&P’s.
Now he is hooked.
He’s a bandwagon type of guy.
I can see we need to start working on Dport.
Your Jedi mindtrick will only work on the weak-willed.
M&P!!!
We will. My bet is he’ll own one by the summer
Ya know, every time I go to a gun show, I pick up one of these to see how it feels.
…one of these times, I won’t be able to put it down.
Oh yes, you’re hooked! We just need to reel you in
