Default M&P 9mm accuracy issues?

I'm picking up on tidbits concerning accuracy issues with the 9mm, searches aren't yielding much valuable info tho.
Are there any issues?

Mostly software, aside from rare mechanical defects.

They aren't bullseye guns, but I trust them with my life.

Most of the accuracy noise is coming from the M4 forum. I haven't been able to figure it out: is it one or two disgruntled owners, or someone wanting to make money on aftermarket equipment, or perhaps just nothing.

From personal experience, I didn't shoot my own M&P 9 as well as other 9s that I own. But my trigger time on the M&P was pretty minimal before I sold it. Certainly not enough time to make a judgement on the inherent accuracy of the pistol.

If you like the feel, buy one. Shoot it. If you don't like the way it shoots, sell it and try something else. Doubt you will lose much if you have to sell. M&Ps are pretty popular.

Long story short since I already had a thread on this, my FS 9mm M&P has early unlocking issues. I have an Apex hard sear and polished/rounded the striker block. It has a better trigger than 80% of my handguns.

Originally it shot 10" groups at 15 yards with 7 different brands of ammo in 3 different weights weather bench resting or off hand, sent it to S&W and all they did was adjust the rear sight, took it to the range and they adjusted it to shoot to far to the right and I still got 10" groups.

While at the first range trip after I got it back I put a 20# recoil spring in it and the groups went down to 4" at 15 yards, went home and my laser bore sighter showed the rear sight was indeed off, I set the sight back where it was suppose to be and am now waiting for Apex to come out for a real fix which includes new locking blocks and/or barrels.

Basically, it's not always the shooter and the M&Ps don't have some special,one of a kind trigger that will take crates of rounds to learn. It may or may not be the gun, but the only way to know is to eliminate every possibility like I did, otherwise people will tell you it's you learning the gun. Not all are effected but mine is and S&W refused to fix it.

That's the short version...really it is.

Default M&P Accuracy

Like NAK posted, I have an M&P that was build in early May 2012 that was not accurate... actually would not group out at 15-25 yards. I would have shots off the paper (25yd slow fire bullseye target) at 25 yds. This was sandbaged on a sturdy bench. Sent it to S&W and they replaced the barrel. My gun was in their shop the same time as NAK. One trip to the range and I'm on the paper getting decent groups of 4-5 incheds at 25 yds... with the still occasional flyer out of nowhere. For a defensive gun, it is now accurate enough. For a competition gun, I shoot better than the gun can. I have a new Glock 34 that was accurate right out of the box. I like the feel of the M&P much better (apex competition AEK), but the glock is more accurate. The glock with a .25 cent trigger job and competition springs is still not the trigger on the M&P.
I will probably try the #20 spring like NAK did to see if I get further improvement. Certainly, the new locking block that apex is developing should increase the dwel and improve the early unlocking issue this gun has.

My new barrel is definitely a tighter fit in the slide and locking block. For those non believers out there... well, my targets tell the truth. Still can't explain the occasional flyer... that is the weird part.... and these flyers are off a sandbag. At least now for the most part I can call my shoots with the M&P.

Believe what you want, but the accuracy of these FS 9mm varies from gun to gun.

Now I feel better. I thought it was just me.

I still dont regret trading a Sig SP2022 9mm for my M&P9 FS though. There is something about the grip that I just really like. The Sig that I had was a fine shooter but I just could not get comfortable with it.

I did have some accuracy issues with the M&P since I know I could shoot pretty accurately with a 1911 to 25 yards and a Kahr CW40 to 10 yards. Right now I average 3" 5 shot groups to 10 yards with the M&P and I'm happy with that. If I wanted better, I would have bought a target gun.

My 9 Compact and my Shield have been very accurate. I posted a photo in the Thread link below of my wife's target....a 68 year old grandma to boot!

my wife loved my shield.

and another......

Default The issue...

The compacts and Shield do not have a know accuracy issue.
All the accuracy (or lack of accuracy) observations are in regards to the FS 9mm M&P

Mine hits where I point it. Is it as accurate as my SIG P220? No My first time shooting it had my confussed because I could not hit the target Went to the range a few days later and had no issues with it 7 10 15 yards. It is not a tack driver but its my home defense and car carry pistol.

To those who own M&P 9fs pistols exhibiting accuracy issues, I really do hope that S&W addresses whatever flaw there is in your pistol.

At 10 yards, I can keep 17 rounds within a 2" group. As I push out, the groups progressively widen. The M&P 9fs shoots so well in my hands that I sold my other semi-auto pistols.

My M&P 9fs serial prefix is DXJ. The test fire date is 3-15-2012.

Well my M&P 9fs was made back in early 2010 and it is way more accurate than I am. When I shot it side by side with a Glock 19 I shot the M&P much better.

Very confusing. I believe all the reports; the ones that say the gun can't group and the ones that say they shoot just fine.

I sold my M&P 9FS just because I had other guns I wanted. I will buy another, but think I will wait until the range reports are more uniformly positive.

I believe it's a roll of the dice at this point since the accuracy issues with the FS 9mm M&Ps began with the introduction of the Compact and S&W changing the profile of the 9mm barrels throughout. I shot my Shield at the same 15 yard distance and got a nice sub 3" group with my first 5 shots. By the end I was getting closer a 2" group and I'll bet under that the next time out.

I just called S&W again and they're sending me another shipping label. I asked how I would know if they would actually do anything this time and the guy said "Well, it will be marked as sending it in the second time for the same thing." yay.....another month of waiting ....hopefully it won't be for nothing this time.

I have three stock FS 9's (FS FS-L FS PRO) that are 3-4 years old and ALL are tackdrivers right out of the case and got better the more I shot them. 9c is a few months old and shoots just as good and getting better. Had the Shield 9 since late April and it's just as good as the rest and getting better as I shoot it more too.

Had the same sear installed in mine.

At 25' 5 shot group you could cover with a quarter.

I started last winter with a 9 FS that would give me 8" groups at 25yds. I know it's not me as I can frequently pull 2" groups or smaller at that range with my Blackhawks and MKI.
Put in a 20lb spring and it got better but I was paranoid so I sold it and got a 9c. No issues with it. 3" at 25yds is fine with me for a CC pistol.
According to the thread on M4c forums Apex is working on a new locking block for the FS to correct the issue but it's been a few months since there has been an update on that project.

Most any gun can shoot better than the shooter doing the shooting. Might be better to trade for a Springfield XD and see if you have better luck.

I've had 7 XDs and they all shot fine, I've had 6 Glocks and they all shot fine, I've had 15 1911s and they all shot fine, 2 P89s - fine,2 P95s - fine,Berettas - fine,multiple revolvers, multiple surplus guns, multiple pocket guns - fine, etc - all fine. Honestly, the M&P is the only gun where fans tell owners to buy something else just so nobody brings up legitimate problems. It's been the same on other forums so it must be a brand thing.

The M&P has everything I could ever want in a poly gun, but the accuracy is not there in my particular model. My Shield shoots close to 2" groups at the same 15 yard distance even though it has less grip, a shorter barrel and sight radius while using the same ammo I tried in the FS.

The thing I see most is the older model owners talk about decent accuracy ,yet you'll get random people talking about the accuracy problem in the FS 9mms, post Compact introduction. It's enough of a problem that a very well known and trusted aftermarket parts company is designing new locking blocks and barrels to improve the accuracy and lock up in models exhibiting these issues.

ETA: I'd link a current thread with 9" groups at 15 yards while being bench rested and pictures of targets from another forum and FS 9mm but I know that's against the rules. Let's just say ARFCOM and leave it at that. I'm glad not all models share the characteristic of mine and many others, but considering it's random, it's hard to pin point the problem in the production line.

I have no accuracy issues with my early manufacture fullsize M&P9 related with the pistol itself. Frankly, it is more accurate than I can shoot it. However, I've seen enough reports in enough places that I believe some fullsize M&P9s are having real accuracy issues.
Hopefully S&W will make everything right for everyone with a problem pistol. It certainly will be more difficult than shipping out a new striker. I would feel much better about purchasing another fs M&P9 if they took the problem head-on...

Nak, I hope they resolve your problem.

I sure hope so since I'm sending it back for another month wait according to the second CS/tech I called today. This one told me to put his name on the box so he can view it personally. I basically told him that I don't want to have the rear sight adjusted incorrectly like last time and have it sent back as a-okay. I also mentioned how another member sent their gun in and got a new barrel for the same issues, which he then replied that I just may need a new barrel.

I'm just glad someone over there is taking a little more personal hands-on approach to this. Everything about the M&P is perfect and if it even shot as good as my Shield, I wouldn't be posting a single thing about accuracy problems since I know it's not a target gun. I guess it's time to play the waiting game again and see how this is hopefully resolved.

Hey there, I've been following this thread for a little bit and just thought I'd chime in. I'm new to the forums (first post) and I have a FS M&P9 that I purchased a few months back. I really hope they resolve your issue and it slightly makes me paranoid about my FS9. I've been to the range a couple of times but have never pushed it out to 25 yards yet. Really looking forward to your follow-up after you receive your gun back from S&W.

Does this accuracy issue vary with caliber? Is the M&P45 more consistent than the M&P9s and 40s?

If you're getting good groups now even at 10-15 yards, I'm sure you won't have any problems. The techs have told me a 3" group at 25 yards is what the FS M&Ps in 9mm are suppose to achieve. If you get say 5-6 inch groups at 25 yards, I call that okay in my book. I'm not going to make self defense shots at 25 yards but if you're looking to use it for competition, then it may be a concern.

Thank you for responding! I plan on doing some range testing soon to see what I can do at 10, 15 and 25 yards. I'm certainly no marksman at this point (this is my first gun). The gun currently for me is for home defense / target shooting. Assuming I should be looking at roughly 2 to 3" or less groups at 10-15 yards? I'm a decent shot but not the greatest so honestly the gun at this point is easily more accurate than I am.

If it's your first gun, your going to learn basic marksmanship skills such as proper trigger pull, grip, stance, etc, so don't get discouraged with groups until you've got shooting a handgun in general first. Remember that the M&Ps sights are set-up so the front sight covers what your aiming at. Many talk about the M&Ps shooting low but that's because they are lining up the top of the front sight with the middle of the target.




ETA: Dropped off the M&P a few minutes ago and should arrive there Monday morning. Hopefully the turn around time isn't too bad.

Thank you for pointing this out I seriously had no idea. This gives me an excuse to go to the range now Thanks again for your help!

Long story short I couldn't hit squat with the M&P 9MM Pro Series gun..even with the APEX Competion trigger parts in it. It was really discouraging. I'm not a marksman but have always been able to group most anything I shot.

I got my son out to the range...a die hard Glock guy that competes on a regular basis. He picked it up...shot it 5 times and put 5 rounds within 1" of each other.

He made me aware of the sight picture pointed out here and after months of practice I now have two Pro Series 9's that I can consistanty group within 2" at 25 yards.

Default M&P 9 accuracy

I got a new m&p a couple of months ago. The grip, sight picture, low bore axis and trigger were overwhelming in a good way. Perfect reliability with several types of ammo. I did have to get used to the trigger pull, to me the percieved pull was light. I polished the sear, trigger bar loop and firing pin block. It has a tremendous trigger. Accuracy was a puzzle. Poor groups and inconsistent. A close look with a magnifying glass showed "chatter" marks on the barrel crown, and it was easy to see that the crown was not cleanly round. I carefully smoothed out the ragged crown and the accuracy improved greatly. It is very acceptable accuracy for the price.
This is how handguns are marketed these days, poor QC, get them out the door and sale them and then fix the returns that come back. This is why there are so many love/hate issues with most all handguns brands. At least the m&p is reliable.

Spot on analysis. My experience and observations (barrel crown, accuracy, etc.) have been exactly the same. Although the groups were "acceptable", they were nowhere near the accuracy of my Glocks.

Here was a 12 yard/36 foot group shot standing unsupported onto a 7" paper plate. While it may look acceptable, my Glocks will clover leaf everytime with no crazy flyers that come out of nowhere.



While I have not messed with the crown, I did pick up a factory threaded barrel, so we'll see if there is any difference this weekend. Out of curiosity what did you do to smooth out the crown chatter?

Ah, that's not the way mine works. May depend upon ammo, grip and your trigger stroke. Now as it happens, that's the way my 5906 shoots 147 gr standard pressure.

This is all pretty interesting because the remarks here are totaly different from those I got on my question (How accurate can the M&P fs be). I had a question regarding the ultimate capable accuracy of the FS models. Of the few responses I got there owners were claiming sub 2" groups at 25 yards to be typical.

Out of curiousity, has anyone tried swapping an after-market barrel into a M&P 9FS with accuracy issues? I know that S&W has "supposedly" resolved the issue for some individual owners by swapping barrels... and I know that some third party barrels are considered as good or better than factory barrels... but has anybody tried doing this to resolve this particular issue?

Thanks for posting the graphic. Just got the M&P 9c and took a bit to figure out sighting. First time out at father-in-laws house, neither of us could hit paper at 25 to 30yds with 5 shots each. Got worried as i noticed for first time that front sight was placed far left of center of the slide from the factory. Took it to range and put more rounds through it. it got much better with 3" groups at 25yds. the more i shot the better it got. A friend was there with his grand kids, so i let them put a few rounds through it. Each one went through a clip before hitting paper but then found their mark with atleast one bullseye each. I like how the gun feels and now shoots after over 100rds. But am bothered by the positioning of the front sight left of center.
Anyone else have sight issues. Was thinking of sending it in to S&W over that issue. but it shoots straight. what would you do?

I agree with your comment about how handguns are marketed these days.
I have not heard the term barrel crown. I know what crown means on a 2x4 board when culling through them to build a straight wall. Is it simular. can you elaborate on the term and how to identify it? Just curious and want to learn. Thanks!!

Just wondering where you picked up the factory threaded barrel? Would like to get one myself. New gun laws go into effect here in Oklahoma Nov. 1st regarding suppressors.

Most of those 9mm's I'm sure were before mid 2010 or so. Saying that there are newer ones for sure that will get 3" and sometimes 2", but those are the exception by and large. The .45's have always been very accurate from what I've read through the years on many other forums. Same goes for the .40's, but there are very few FS .40s that have accuracy problems, but I've read there are some. Nothing that S&W won't fix for you though.

I assume most aftermarket barrels are just a little bit bigger and have less play. I know that Grant from G&RTactical is getting __Oversized__ barrels from Storm Lake that they will ONLY allow him to install. They have to be custom fitted to the slide, that's how he's been getting 1" to sub 1" groups. He's charging $200 with it fitted, which is a good price, but then again you shouldn't have to do this either. I know if the M&P 9 FS were coming out of the factory getting 2" groups there would still be people paying for 1" and below groups, but it wouldn't be many. Apparently custom fit over-sized barrels is what the S&W Pro shooters have been getting for years for the M&P's, and I assume any gun they get that's not a revolver.

Now hopefully Apex's new locking block will make most 9mm FS's the way they should of been from the factory. I'm sure it'll make the M&P9C a little bit better, but I'm not 100% sure on this. I'd assume it'd make the .40's tighten up the groups a little bit more.

Let's hope in the future that S&W will have lasers on the mfg line that will read the dimensions of the whole slide down to 10,000's of an inch and also the barrel. Then they'll have to program a way of trying to match the slide to the barrel as best as they can. I'm sure it would improve the accuracy on all of the guns that are produced. Now if they also addressed the dwell time in the M&P 9 FS it would make them more accurate right away, but if they also did the laser matching it would be very, very accurate I'd assume. I'm sure it wouldn't be cheap, but maybe if they do an upgrade in 5-10 years they might look into something like this. First step is fixing the issue with the dwell time right away. It'd be nice if Apex could license the new locking block to S&W and if you'd call them with your M&P9 FS you'd get one. Maybe for your M&P9C and M&P40 FS you'd have to pay a little money for one.

I've been waiting to purchase a new M&P9 FS from Grant, which I guess the barrels won't be ready until end of this month at the earlies or probably mid August. I've been looking on local AL postings and keep coming across G17 and G19 Gen4's. I shot a G17 G4 but it had the FTE issues a lot. It was very annoying. I'd much rather have 6" groups out to 25 yards with the M&P9 FS (which I think is very unacceptable though) than 9mm Gen4 FTE issues which can really ruin your day if your defending yourself. Was a good deal on the G17 Gen4 for $450, but still couldn't bite since just don't know if you'll run into the FTE issue right away or from what I've read it's more prone to happen after 1200 rounds or so.

I just wish I knew the estimated price on the Apex locking block, if it was $25-30 shipped then I'd just pick up a used M&P9 FS and be done with it. Since their stuff is generally pretty expensive, then that's why I'm very heavily leaning towards the $200 custom fit barrel. Why I'm willing to wait to get a new one from Grant is so I don't have to pay SH back and forth for the slide, so I'd save $25-30. Then again I assume you could do USPS though, but haven't looked into that though, then it'd be a lot cheaper than that.

Oh I forgot, I would sell the Glock Gen4 once I knew if I'd go the Apex locking block direction or the G&RTactical one. Even though I just might get a M&P9 FS that does shoot good enough (under 2.5" to 25 yds). I will eventually start shooting out that far.

Are there any issues?
The rear site on mine was way off center when I got it...moved it...and now at 10 yards, I can shoot the center X out of the silhouette target.

I also added an inexpensive Sig Sauer laser site to it...for night work. (I have the 5" Pro)

Default barrel crown

I used a dremmel tool attachment-cone shaped stone/grinder and wet/dry 400 grit sand paper, all BY HAND. NO power tools at all. The crown is critical to accuracy because it is the very end of the rifeling that the bullet is in contact with as it exits the barrel. There are different profiles at the end of a barrel, some are flat, some are flat and recessed and some are round. (the recessed style is to protect the muzzle crown) Regardless of the profile, the concern is where the lands and grooves stop and a slight taper opens up from the bore. This is easy to see. What is critical is that the crown is symetrical, with no imperfections at all. It must allow the bullet to exit without being upset by a burr or being sent wobbling because the crown is uneven.
First I noted the deepest part of the rifeling and worked the rest of it down to that point, making very sure it was square. This was a very small distance, just enough to bee seen with the naked eye. I hand turned the cone grinder bit and checked often. Then the 400 grit with oil to hone and smooth everything.
Be careful, you can ruin a barrel, but if you are careful and patient this can be done and if you have ridiculous sized groups, It wont hurt unless you are sloppy. This worked for me.

I bought my M&P9 fs MPNxxxx back in 07 and have fired over 500 rds down range, after that I stopped counting. I shoot 3-4 " groups most times at 15 yrds. About 4 months ago my brother in law qualified with it for his CCW permit and the instructor had to double check due to all 30 rounds going through a 4" hole. He had never shot a M&P ever before. He then bought one and feels its not as accurate, was having hard time grouping. I asked to shoot a quick couple of rounds just to see and was still close to 4-5" group, He does not clean, break in or lubricating his weapons like I do. I love my M&P, trust it with my life and would never get rid of it.

So what changed around 2010 that earlier guns seem to be considered more accurate? What would be the serial number prefix range to look for / avoid ?

With so many guns being made/sold maybe it time for new tooling ??

I have had decent accuracy with my FS M&P's, just consistently low left, tight patterns. I was rifing the fence on Apex kits, but finally boke down and did the Burwell technique, and really lightened up the trigger. As far as objective measures, I don't have any. But my USPSA scores when from dead last to 50% at the first match after sear polishing. Also at the same match, I knocked down each steel with a single 115 gr round per target, down from from an average of 1.5 rounds per steel.

I am basically a Sig shooter but I wanted to try the M& P but my local gun shop had a used 40 SW at a good price. I bought it and a 9mm threaded barrel. Accuracy very good and no hiccups. Is the 40 accuracy no problem and the problem just lies with the 9?

Stay Safe!

From what I've read it seems to only affect the 9mm. Something about the locking block being not enough of a redesign from the .40 so the physics aren't quite what they need to be.

Excuse me?? Where did you see that piece of information? I have four 9mm M&P's and every one is more accurate than I am. It's a tried and true design from day 1.

This target was shot by my wife...her 3rd magazine out of her new 9mm Shield from 15 yards. Bad shooting is seldom the gun's fault.
