A year ago I purchased a 40c and liked it so well that recently I purchased a used full size 40. The used fs has a lot lighter trigger pull then the c. It's a dramatic difference. Is this typical or could it be that the fs has had some trigger work done on it?

Anything is possible with a used gun.
Does it say "Pro" on the slide? Those come with a lighter trigger.

2 part answer, the M&P triggers are kinda all over the place, not like the Sigmas but I've got 2 buddies who also have 40's and all 3 of ours feel different. See if your range has a trigger scale. It should be at 6.5lb. A lot of people have the full size polished for a smoother break. The 40c's seem to come thru stock with a nice clean break with the 40fs's don't. I know mine could use some help.

Do the compacts come from the factory with heavier trigger pulls than the fs in the m&p line? Is my compact trigger going to loosen up after anwhile. I probably have around 500 rounds through it.

Per the Armorers manual there all at 6.5lbs. But With S&W it's usually +/-2lbs. Thats probably what your feeling. It may smoothen out a little but I doubt it will lighten up. I'd have them both weighed to see where your at and make a decision from there. If your anything like me having totally opposite triggers screws you up. Especially in the case of two guns that feel the same in the hand but with very different triggers.

Yes!!! Transitioning between the two is difficult. I feel confident and accurate with each, but going from one to the next is a challenge. I am not sure but I can be real confident saying my .40c has a lot heavier pull than 6-7 lbs. I plan to find out though.

A couple of things could be in the works.

One - Did you buy the 40c new or used? Is your 40c a MA (Mass. state) model? If so, maybe it has the 10# trigger pull on it vs. the normal 6.5# trigger pull. Maybe that's why it feels so much different than the stock 6.5# pull of the 40fs.

Two - If you are positive your 40c isn't a MA model and has the stock 6.5# trigger pull, then are you sure than the person didn't put an Apex kit into the 40fs? If so, that drops the pull down to like 2.5# or 3# and that would be a difference between the stock 6.5# pull of your stock 40c.

Again, the only way you'll know these numbers FOR SURE is to use a meter on them to find out the actual weight of the trigger pull for each. Then you will know without a doubt.

When you buy a used firearm from someone, sometimes you never know what you're going to get. That's the only bad thing if you buy it off someone you don't know. So, I would check into those two options above and it might give you some insight.

I did buy the 40c brand new but that's interesting. I live in Texas so I would think it's not the MA regulated version... Hhmmm... Nothing else to do but weigh the pulls on each. Thanks for all the help.

One thing I can tell you is I have a 45c and I have put around 700 rounds through it and I can say that the trigger has deffinately smoothed out. It doesnt have that scratchy feel any more. (if that helps at all brother)

check the SKU: number on the box for the 40c. SKU: 109253
is the MA compliant one with the 10 lbs trigger pull

If what your saying is true, I have a MA compliant gun.... And I'm in Texas!!!

They don't just sell them in MA. It's just made compliant for MA, but they get shipped all over the US depending on who wants/needs them. Sometimes a dealer will take them because they can get a deal on them from S&W. So, it's possible the dealer in TX got a deal on them and that's all the M&Ps they could get at the time, so they took them. However, the dealer probably should have mentioned it at the time of purchase that it was the 10 lb trigger pull version (MA compliant version).

So, that's why your 40c has such a heavy trigger pull and feels so different compared to the other. The other version probably has the "normal" trigger pull or if it has the Apex kit in it (you'd have to ask the previous owner), then it probably has an even lighter trigger pull than normal.

At least now you know why they feel different.

I appreciate all the info. If my fs is a typical trigger I sure don't know what anyone would fuss about it. Then again I have only shot a hand full pistols and might not know any better. I sure like it, but that makes my 40c seem terrible. I wonder if I could have a little work done on the current trigger and get it comparable to my full size or do I just need to invest in an apex trigger?

Depends if you have a competent and qualified gunsmith that knows M&P's in your area and how much it costs for them to rework the trigger pull. Ultimately the Apex kit might end up being cheaper. I don't know because I've never looked into either and I'll bet that gunsmith pricing varies depending on location.

I have read about the Apex Kit but I'm not sure what all I should install on mine being that it's an MA complient version. What should I buy and have installed if I want about a 5lbs trigger?

I would think DCEAK version.

https://apextactical.com/store/produ...php?pid35.html

My local smith quoted $40 for install if you don't want to take it on yourself. Check You Tube, there are detailed installation instructions.

FWIW my 40c with a standard trigger felt better than my 9Pro. Go figger.

I've seen MA guns for sale here in VA too, dealers grab them thinking the 10rd mags are the only difference. The Apex kit is the way to go, It being a MA gun makes no difference. I'm from MA so I know ALL about getting around their ****. Imagine if ALL your semi's had that trigger! That kits give you a consistent 5.5# trigger. I've heard nothing but good about it. The free state triggers are lighter (6.5#) but there still not great. I bought my M&P after I moved out of MA and I'm still gonna put the kit in.

I have read that some opt to leave original sear spring in the MA complient pistols... Should I install all the parts that come with the kit?

I wouldn't recommend mixing and matching, You wan't to "UN" Mass the gun. Don't forget the springs in that gun are the only thing that separate that one from the production models. There's no physical difference. You should take a look over at Northeast shooters for reviews of the kit as almost everybody in MA installs it, or something like it.

I am in MASS and yes the triggers suck.

Do you have 10 round mags ??? If so it's a most likely a MASS gun, we are stuck with 10 round mags as well as the sucky triggers.

I have had Greg Derr do trigger work for me as well as a few other things to both my M&P's (a 40 FS and a 40c).

Greg Derr - Precision Pistolsmith

You can have a Gun Smith check both of your guns and have them do a trigger job or you can install the APEK kit or kits or you can get a S&W trigger sear and install that.

Smith & Wesson Sear Housing Block without Integral Lock and Magazine Safety S&W M&P, M&P Compact 9mm Luger, 357 Sig, 40 S&W - MidwayUSA

Gunsmithing - Shop Gunsmithing Tools & Supplies at MidwayUSA

I bought both of my guns new, my FS had a trigger pull around 10 Lbs, it worked down to around 8 Lbs, my compact came with a 15 Lb trigger that worked down to 12 Lbs.. Both guns are now around 5 Lbs after Greg Derr worked his magic on them.

Myself I would have a gunsmith sweeten the trigger.

Hope that helps.

I have a MA M&P9c with 10lb trigger. All I changed is the sear and trigger return spring. I used the apex sear and a standard trigger return spring bought from brownels. The MA trigger return spring is heavier. I did not change the sear spring. Leaving the heavier MA sear spring in actually helps give it a better reset. My result is a 5lb trigger from 10lbs. This cost about $43 vs $80 for the whole kit.

Changing the sear is easy. The trigger spring is a challenge lining up all the parts. Apex has videos on youtube on how to do it.

Check your trigger weight first though, just incase it's not a MA trigger.

Just wondering about the 10 round mags, I've been doing some homework on the M&P 40c and it states they all come with 10rd mags, 10+1 to be exact, but the sales person that I purchased my M&P 40c yesterday stated it came with 9rd mag 9+1??? Is this a possible MA 40c, what else besides the SKU# can I look for and is that SKU still accurate?

I'm in mass as well, I bought my shield and my FS .40 new (at 4seasons) and had Greg do both of the triggers on them. (5.5# pull on each).
Actually cheaper than the Apex kit and he does a great job.
Look around locally you should be able to find a good gunsmith
near you that can tell you exactly what you've got with both guns.

Necro-thread... revived yet again!

OK, I'll bite on this old brisket since the problem is still very relevant today.

I've "fixed " at least a dozen of the MA version M&P's and Shields
Here are my thoughts .
First, you need to know what you have as what you need to do depends on where you start. IF you don't have access to a trigger scale, try a fishing scale. If you don't have a fishing scale, try hanging a 5 gal bucket off the trigger and fill it with water till the trigger breaks. (Then weigh the bucket.)

If you have a MA gun, the trigger will be in the 10-12# range. IF you have a stock 48 state gun, it will be closer to the 6-7# range ( depending on production date /how "used" it is.)


Assuming you have a MA gun, there are two easy DIY ways to cure the trigger. Both involve replacing the sear with an Apex brand. ( You can save $40 by heavily reworking the factory sear via Burwell's online instructions but I don't recommend it for a newbe gunsmith). Replacing the sear alone, will get you into a crisp 5.5 -6.2# range. (Read: just right for a carry gun.) Replacing the sear and the trigger return spring, can get you down into the 3.5-4.2# range (which IMHO is great for a range gun but too light for a carry gun.) In either case, leave the sear spring alone. It's heavier but works well in either combination. The Apex sear is $40 all over the net. The trigger return is $3.33 from Brownells. Elbow grease is free if you want to polish some parts while your in their.

As for the complete Apex kit, you can invest if you want but I think 90% of the improvement can be found in the above mentioned parts alone.
