M&P 9C model"H"

[lmacrichter]

I bought my M&P 9c about 6 weeks ago. I am new to S&W and semi-autos and saw several comments on the "H" model being improved. How do I know if I have the "H" model?

 

[N4KVE]

It is not a different model. At some point in time they changed the trigger bar, & the new one has a "H" marked on it to identify it as the newer bar. There is no way to know if a gun you are about to buy has the "H" bar or not because when they build these guns, they use whatever bar they have, & they are not going to throw out the older bars. And considering the thread about stripping guns at the LGS before paying for them, I don't think that will happen. So once you do buy the gun you are looking for, remove the slide, & look at the trigger bar, & see if it has the "H" marked on it. GARY

Is your M&P green or do I need to visit the eye Dr again?

Ima..., lock the slide open and look down thru the ejection port to the right front corner of the top of the mag well. You will see a silver colored metal bar that runs along the upper right side of the mag well. That is the trigger bar. Using a flash light, look at the inside front corner of the trigger bar just as it comes from the back of the trigger and bends toward the mag well. In the inside corner of the trigger bar, you will see a small stamped letter. If it is a "H", you should, by most accounts, have an newer "H" series gun. Like N4KEV says, it's not a new model, it just has the newer upgrade parts. This should include a new style slide stop bar, a new style sear, and the faster twist barrel, if it's a 9mm. Also if you will look at the date "code" on the end of the box, or the evidence cartridge case fired date, they will tell you when the pistol was built. I just purchased a lightly used 9c dated august 2013. It has all the upgrade parts in it. The "H" series trigger components make a big difference in trigger feel on the M&P's. I like a bunch!

My 9c has the H stamp on the trigger bar with a date of 5-14-2013 on the fired bullet envelope and I don't remember exactly when I bought it but have had it over a year. The more I shoot it the better I like it.

 

[Ofc.JL]

Yepper, the "H" series M&P's are very nice. Good all around platform to begin w/ and w/ the "H" improvements, much better.
Daddy Like! lol!

LOL!!! Your eyes are good, I have the VTAC.

MP9C "H" model

Thanks for the help. My gun was made on 1/28/14 and is the "H" model.

 

[N4KVE]

Can someone order a "H" bar & install it in a 2009 M&P40c & notice an improvement?

 

[Prasko]

Unless you have the new sear housing block with the new sear, wouldn't recommend it.

The new trigger bar came about to work with the new sear geomitries and sear housing block. The sear engagement loop on the H bar is higher compared to the S bar.

Putting it in an old gun may, probably will, have problems.

As far as triggers go, I notice a lot less flex in my "S" stamped trigger bar on my full size 9, compared to my newer "H" trigger bar on my compact. Was miscontruing it for trigger creep, but it's actually the trigger bar flexing before the sear breaks.

 

[Prasko]

H bar on top, the loop is taller and more angled. This is to compensate for the new sear geometries.

You sure that isnt an "I"?

 

[Ofc.JL]

Hmm! Might dang well be! Could easily stand for Improved. Way to tell(perhaps!) would be compare the orientation of the "S" (Standard?) trigger bar. If the "S" is on it's side, then it may well be an "I".
Anybody? Pictures, please.
Thanx.
BTW, if it is an "I", I am gonna feel like an Idiot. I called it an "H" trigger bar because that's how I first heard it.

 

[Jiman]

I suppose it could be an "I".

The pic from Prasko does show both the "H" and "S" stamps. Assuming the orientation is consistent it would be an H vs. I roll mark...I think

How many letters are there anyway?

 

[Ofc.JL]

Early trigger bars were not marked at all, IIRC. Now, "S" and "H" marked trigger bars, I believe.

 

[Lost Lake]

I'd like to compare a new trigger assembly to my polished one.... May have to buy another M&P just to see... rats! Another reason to buy a new gun

.

 

[Ofc.JL]

Well, If I can get my head out of my *ss, I might have looked at the MSW picture member PRASKO posted. Upon close examination of the 2 trigger bars in the picture, is does show the "H" stamp to be oriented the same as the "S" stamp. So I do believe we can safely call it the "H" trigger bar. I still have no idea what the "H" might stand for. Any thoughts, anyone?

It's just a revisional mark I believe.

The bars, as far as I can tell, are identical except for the sear engagement loop.

Some people believe you need the new bar to get a better reset if you get the new slide stop. That is incorrect. I have the new slide stop and an "S" bar, and my reset is the same as my compact, which has the "H" bar.

The main updates were the sear housing block. The new ones cannot accept the RAM, but the new ones have the performance center sear dimensions.

The only reason I would see needing a new trigger bar, were if you updated to the new sear.

 

[Ofc.JL]

Prasko, of course you are correct. The bigger loop on the trigger bar changes the triggers' dynamic feel. Trigger seems to set up later(or deeper in the pull, if you will), and breaks cleaner, w/ less backlash. Of course the cleaner sear break is because of the newer sear.
And you are correct on the trigger bar and slide stop. The new style slide stop has the build up on it, to give a stiffening point to the trigger bar so the trigger bar has a more positive reset. While I have not tried this yet on an older M&P(and I plan too, if I can get hold of a new style slide stop), the newer style slid stop should give an older M&P a good reset, all things being equal. That's all a RAM does. My carry .40FS is box stock w/ a RAM and has a very good trigger from break-in and good reset w/ the RAM.
G&R tactical has them, but w/ a $50 minimum order policy, I would have to buy 3, and I do not need that many. I need 1 for a .45FS, and maybe 1 for my carry .40FS.

Well we've been talking about H stamped Trigger bars for almost a year now, so it should be fairly common knowledge... not sure where the "I" theory came from... .

FWIW I'm running the H on an "old" 2012 Sear block with no issues, of course the SHB is full of Apex FSS components .

Another tip - if you are using the FSS kit from Apex, no need to rush out and find a Gen3 Slide stop with the stepped bump, as with the FSS geometry it never get's engaged anyway - not enough forward trigger travel with the FSS installed.

 

[Johnmuratore]

I've got a .40c, test fired in Sept '13 with the "H" stamp also.
Stock trigger and I've always liked it.

 

[ScrapmasterFlex]

I cannot wait to drop knowledge on another forum and bust out my "sear geometry" on them. I am going to sound like a gun genius.


You ain't got no good sear geometry, son, I got that new sear geometry ! Your geometries are whack.
