Is there anything out there outlining a detailed strip of the upper and lower of the M&P? I used Dan's trigger job page to work on the lower but it doesn't show how to take the entire trigger out.



I ask because as I was cleaning my pistol tonight I noticed that the trigger spring has what looks like cotton stuffed in it. I use Q-tips in the hard-to-reach areas but was pretty confident that I couldn't have possibly stuffed that much cotton in it. It looks full.



Any ideas?

No, you're not imagining it, that is something that is supposed to be there. I actually think it's some kind of foam. I have no positive idea on it's purpose, but it could be for lubrication, for dampening the spring after the sear releases, or for catching crud (like it seems to do).

LOL - thanks for the reassurance. I can't imagine why it's there but I'll leave it for now then. I had been running a Q-tip by that area and thought that I had some how left a bunch of cotton in the spring.

If you do a complete tear-down of the gun sometime and remove the trigger spring, just pop that foam out of there and rub it between your fingers in some cloth. That will clean it up some.

It's supposed to be there, and it's needed.



If it goes missing, S&W says replace it and the spring.



Similar set up in the Sigma. When those plugs go missing, and the gun is shot, spring eventually breaks. May take a few thousand rounds, but it breaks.

Does anybody have an M&P Armorer's manual? I haven't seen any on the Net, as of yet. I've been an unofficial Glock Armorer for a few years now without ever attending the school. I would like to achieve the same with my M&P. Anybody?

That's interesting about the harmonics killing the spring. ON the Sigma I could see it because of the massive amount of tension that spring is under when the sear breaks, but the M&P has a much lighter spring. Hmm...oh well. Smith knows what they're doing.

I would counsel against a detail strip of the M&P without attending an armorer's school. I just completed a course on the M&P a couple of weeks ago, I've also been an armorer on 3rd Gen pistols for years. The M&P is not a particularly difficult pistol to work on, and I find the design and engineering to be very impressive. Like most pistols, however, there are a couple of things you need to know in order to avoid breaking or loosing parts in the detailed disassembly/reassembly. Also, knowing things like not removing the dampener from the trigger spring helps keep you from doing things that will cause problems later. This is one of those "if it ain't broke, don't fix it" sort of things. You should be able to keep your M&P running fine with just the typical field strip & cleaning procedure you would use with any other pistol. If it requires more than that, contact S&W or someone who was trained by them as an armorer.

I have a service manual for my John Deere 3320. It shows everything one could want to do to it. I like knowing how, even if I don't pull the Hydrostatics apart! Got anything we can use? It sure would be appreciated by those of us who feel that knowledge is a "good" thing!!

I don't have a problem detail stripping the M&P.

And I have not attended an "armorer's course" either.

I posted the file from Brownells so I didn't have to scan it from the book.



It is originally from page 15 in the M&P series armourer's manual.
