If you were unhappy with the last two, I don't understand why you would buy a 3rd. Does this mean you'll try for a forth 9FS.

S&W has never made a M&P9-1, with a new set of specifications -- they just do rolling changes. Many of their parts come from sub-contractors and I guess that means a given M&P can be set up differently from those sold a month before or a month after.
The "new" barrels have the dimples on the bottom -- indicating, supposedly, a different twist rate.
After owning quite a few M&Ps, I sold my last one off because of very unsatisfactory accuracy. Sad to say, the best accuracy I experienced was with an older one (2010?) that had a Storm Lake barrel. Although I own many S&W guns (SD-9VE, 3913, Mdl 10, Mdl 640, Mdl 642, Mdl 442, Mdl 65) I have sworn off M&Ps until they improve the accuracy and have gone with a FNS-9 instead (now there is an accurate pistol).

Since the OP is not going to answer my question, I'll just tell you the answer. In the manufacturing industry, it's called a rolling update. Since there wasn't anything wrong with the old parts, they keep using them until they run out. So, it entirely possible that an older trigger bar was still in the bin when this pistol was made.
As to the "older" barrel...
There is an actual barrel profile change that was made. Those haven't been made for about 8 years though so, I don't think one of those is in his gun.
Also, I was told that certified armorers can order parts straight from the factory that we regular guys can't. So, he could just order the "H" bar if he wants, no?
As to the "older" barrel...
...this is the common mistake. The dimples have nothing to do with the twist rate. They simply denote which machine or process line they came from. So, if his barrel has no dimples or just one and not two, it doesn't matter. Of course he's a certified armorer so, he knows this already and it shouldn't be an issue for him.

FWIW, I just checked both of mine. Both born in 2012, the 45c has a 45 stamped in the triggerbar, as you might expect, and the 40c has an s.
What's the significance of the "h"?
What's the significance of the "h"?
The "S" trigger bar has a 32 degree loop, and the "H" trigger bar has a 40 degree loop. The "H" bar is supposed to have "better engagement" with the sear, and the new "H" bars are needed to keep the trigger pull weight up within normal spec (with the PC sear being used).
As was already mentioned, the machining marks on the barrels (dots) are used to track the machinery/operator when they were made.
I've not been keeping a 'constant' awareness of the changes and revisions being continually included within the M&P pistol line, but then I've only attended a few (4?) M&P pistol armorer classes, and the company's engineers are seemingly always making subtle improvements to their products between the recerts I attend.
If it were me, and I was buying another M&P pistol as an armorer (I only own 2), as long as it came with the PC sear in the latest sear housing block (which won't fit in an older frame, meaning approx 2010 and earlier) and the newest yellow wire slide stop assembly (with the welded built up 'pads') was present, I'd not lose any sleep over it not having the "H" trigger bar.
Besides, as an armorer, the gentleman can call his region's LE sales rep, or the company, and order a new/current trigger bar for his gun. If calling the company, they've been using the serial numbers of the guns to look up the production run and make sure the right parts for the production vintage are sent. I was told it was a new computer parts system they've been using for new production guns (and it doesn't include the 3rd gen guns).

Thanks. Would there be any benefit in installing the new triggerbar?
I didn't notice a particularly significant improvement when I installed some of the revised parts in one of my own M&P's, but then mine already had a pretty decent trigger with the original 2010 vintage parts. It probably helped that I shot it a lot.
I've handled and used some older M&P's belonging to other guys, mostly M&P 9's and 45's, that developed some very smooth triggers, which also measured lighter pulls, just from shooting them.
I'm more or less of the "don't fix it if it ain't broke" camp.

I noticd a significant improvement in mine just by removing the striker block, polishing the heck out of it, and smoothing the channel it rides in. I also cut about 1/8" from the spring, too.

Sorry, Gentlemen, Easter vigil weekend. As far as my 9FS I just received, I did check w/ the factory and even the customer service rep was surprised. This pistol shows a Nov 2015 build date. But if you compare this pistol w/ any other recently made 9FS, this pistol is a 2 1/2 year throwback to what S&W is sending out now. It just doesn't make any sense, knowing what S&W is making now. I will explain the problem to S&W politely, but short of a complete refit to what they are making now, I will dump it when I get it back and will have to think long and hard before I try another 9 FS M&P. Which is sad, as I really like M&P's. A lot. Thanks for the comments, Guys. This 9FS pistol debacle still has me disappointed. I will report what happens as it goes.
Happy Easter my Brothers.

Never heard of the H trigger bar but I just went to check my 9c which I purchased about 18 months ago and it has an H on the trigger bar. Guess I lucked out.
My 9c was made in July 2012.
It shoots where I aim it.
It goes bang and cycles every time I pull the trigger. The trigger is a little gritty but somehow I can shoot small holes in targets with it. I've got quite a few thousand rounds through it and it runs just fine. Should I start worrying about it breaking?
Considering the fact that it doesn't have an "H" stamped anywhere (as far as I can tell), and seems to be quite old since made in 2012, should I be upset? How about "high dudgeon," as I hesitate to say "pissed" on a public forum? Is it still considered tacky?
I'm just a baby boomer trying to pass for a millennial, and often miss the nuances. Please advise.

If you mean shortening the spring that tensions the firing pin safety plunger, that spring needs to function the plunger even in "less than optimal" conditions, meaning when fouling or other contaminants might be present. I'd not reduce the tension, myself.

Like I have explained in a earlier post, the "H" trigger upgrade was indeed a rolling change that S&W implemented after the they introduced the Shield. S&W engineers redesigned 3 parts in the M&P series of 9mm and .40 cal pistols. They are the trigger bar(marked w/ an "H"), the slide stop or slide lock lever set, and the sear itself. The reason was a quicker, crisper sear release w/ a postive trigger reset. They did this due to all the complaints from consumers on the mushy trigger sear release and the almost imperceivable trigger reset. It was bad enough that to this day, most people that buy or own M&P's think they MUST put an APEX trigger kit in it so they can shoot it. We know that is not true, and the "H" trigger upgrade is just as good as an APEX system, w/ o spring replacement. S&W advised us that the rolling change was ongoing and how new M& P's would be from now on. Somewhere during this time, S&W also did an upgrade on both the barrel and fitting process on all newer M&P's 9's from about mid 2013, to address accuracy issues. (My last 2 9's would not shoot into 18" at 25'!) Now if all that is true, how did I get a pistol that was made 4 months ago with 2 1/2 year old out of production parts? ALL of any new M&P 9 or .40 pistols I have seen for sale anywhere in the last 2 years have been "H" trigger upgrade guns. So I am less than pleased when my brand new carry pistol is out of date by 2 1/2 years. I will let S&W answer that.

Since you've had such horrible luck with M&Ps, I've gotta ask, why do you keep coming back?
That leads to the next question, how do you know it's the guns and not you that's shooting 18" at 25 yards?

I'm hoping he can get this straightened out.
