Don't know the part numbers, but the H trigger bar and the slide stop with the welded on bumps were the newest parts and made a lot of difference.

Quote HistoryQuoted: So 2 parts needed then? Technically you just need the new slide stop to get the reset click. The H-bar may improve trigger feel slightly but YMMV in which feel you prefer more. https://www.youtube.com/watch?v=dP4e1ZvI4GY&ab&ab_channel=Rickfrom406 |

I ordered both the H bar and gen 3 SS from Brownells for under $40 shipped. I could've just welded a tit on the OEM SS but figured I should just try stock parts instead.

The sear was changed as well when they went to the H trigger bar so you may need that.
I believe you have to purchase the whole sear housing block as a complete unit. |

Not true, you can put all of the newer revision parts in the old housing block with the hole in it. I have one early CORE with new internals in it and it functions perfectly fine. |

You sure about that because if I'm not mistaken they changes the sear return spring from 1/16" to 1/8" as well to fix a dead trigger issue they were having. Not sure how you will put a 1/8" spring and plunger into a 1/16" hole. |

Not sure how you will put a 1/8" spring and plunger into a 1/16" hole. You are right. IIRC the earliest model sear housings had a 1/16th hole, thanks for reminding me. However there are early model housings with a 1/8th hole as well, the only way to be sure is to pull the sear and measure the hole. I just checked the large hole sear block I referenced in my earlier post and verified that it is indeed 1/8th, but I have a spare laying around that is 1/16 and the blocks are indistinguishable other than that one hole diameter. |

I have a VERY early M&P, and my understanding is the frame was changed and I cannot retrofit one of the newer sear housings into it?

Yes the old sear housings have a big hole in the side and a different frame rail cutout shape. However you can upgrade all the internals to the new revision ones except maybe the sear spring/plunger since some of the old blocks have 1/16 holes. Alternatively you can look for a mid production old style block with a 1/8th hole or just drill the hole out yourself to 1/8. |
