Accuracy Problem (9L)?

I have about a three year old M&P 9L. I like everything about the pistol, but I have not been able to shoot it well. The last time I shot it, it was from a rest, and it seemed to shoot all over the place. I will take most of all of the responsibility for my poor shooting, but I have to wonder, do I have to look elsewhere to get better accuracy out of a 9mm pistol with a 5 inch barrel? Is this gun capable of good accuracy? Joe

This is clearly a loaded question to be asking to a group of M&P owners who have committed to the platform many times over and continue to do so everyday. I think you'll find while we all feel we can improve we also feel we shoot our weapon well enough or will shoot it well enough to keep putting rounds down range.

Accuracy is also dependent on what "type" of shooting you are doing and what does accuracy mean in that type shooting (e.g. self-defense shooting accuracy versus target.). Personally I'm all about SD accuracy but occasionally shoot for "target" accuracy and find that with my 9L I can group about 2.5-3" on a good day at 25 yards. That's plenty good enough for me.

The pistol shoots straight, as they say: practice, practice, practice.

Thank you for your good answer, Jacksonport. One does risk stepping on toes when making less than positive comments about a gun on a forum with the same name. I appreciate your honesty.

I am a less than stellar shot and am badly in need of more practice. It just seems that I shoot some guns better than others. Even my M&P 9C seems to work better for me, which suprises me. I also shoot my 1911 better, and even my EAA Witness Poly 9 with a 4.5 inch barrel seems to yield better groups. I really want to like my 9L, so I guess I'll just practice until things improve. I'm glad to hear about your good shooting with this pistol. This is a hopeful sign. Joe

m&p 9mm are fairly notorious for inaccuracy at distance. Mine wouldn't get better than 10-12" groups at 25 yards. I sent it back and they replaced the barrel. Now it get 3-4" groups at 25 yards.

What kind of groups are you getting and at what distances. You need to put it on a rest and test it at 25 yards or so. Let us now what kind of groups you are getting. There are many threads, including my own, about this issue. However, I think S&W changed a few things and accuracy is much better since late 2012.

Find someone who knows proper shooting techniques that is a good shot and have them give you pointers. I paid for instruction, practiced a lot, got good at it and I now instruct others.

This is what I'm talkin' about. Thanks 3d. I heard something about new barrels with different twist rate. Don't know if that's one thing they do differently these days. I called S&W and will be sending mine in. This is not to say that I don't need more practice and that a good deal of my trouble is with my shooting. jrh

It's funny how small thing make a big difference. Even things like changing the backstrap can affect where the rounds end up. Just a suggestion and not a criticism, maybe get some training or pointers as everyone has said, as well as, maybe having an experienced shooter try out your gun before you blame it. Hope this helps!

I own 9 full size M&P pistols three of which are in 9 mm. I bought one of the 9's in 2008. It was not as accurate as the later models, however, accuracy was acceptable for SD situations (It shot about 6 to 7 inch groups at 25 yards). I changed out barrels and got it down to 3 to 4 inch groups at 25 yards which is about as good as I can shoot a combat style pistol (on a good day, I can get 2 to 3 inch groups but as I get older and my eye sight gets worse, my groups have tended to spread). I shoot about the same with my Glocks. My Browning Hi Power and my 1911 are more accurate than any of my M&P's or Glocks. You might also want to play around with bullet weights.

The inaccuracy issues are definitely VALID. That doesn't go to say that inaccuracies can't be shooter induced as well. I would just like to point out the fact that the barrel lockup issues are indeed a existing problem for some.

My current M&P 9 FS that I bought today has a VERY VERY tight barrel lock up. Born May 2013. Also the trigger is out of the box lighter, crisper, and better than usual reset. Can't wait to shoot it.

Older M&P's were reported to have a lockup problem that impacted their accuracy. I know when my M&Pc was skads more accurate than my FS (until I ordered a KKM barrel).

-Have you tried it from a dedicated pistol rest to test the grouping. This is a specific device that takes the human factor out of it.

-Alternatively have other good shooters tried it from a rest?

If either is yes and has the same result you might get a Storm Lake Barrel. KKm is making a full size and L/Pro barrel as well

Two things effect mechanical accuracy in a pistol:
- The tolerances of the barrel. In hundreds of thousands of guns, you may have gotten a slightly out of spec one.
- The trigger. Smooth, crisp, short trigger pulls effect accuracy, even from a rest. If your gun is plagued with a long, heavy, gritty trigger... you'll need to improve it.

Outside the mechanics of the gun, your next fix is ammo. Some guns prefer heavy slow bullets (147-160gr 9mm). Some prefer lighter, faster bullets (115-124gr 9mm). Try both.

With a quality FACTORY barrel, quality trigger, quality sights, and the right ammo... your 9L should be capable of ragged holes at 7 yards, and 2-3" groups at 25yds. Whether YOU are capable or not is the only question.

Jeff has the way of it. I'd second his post and work through them point by point. PLus at the end of it, with a competition barrel, trigger job, and perfected ammo that your pistol prefers, you'll have a very accurate M&P.

My two 9MM guns both have the slower twist barrels and both won`t shoot 147gr bullets worth a hoot. I have had bullets tumble inside of 10 yards. S&W is now producing the barrels with a 1 - 10 twist, a more common twist rate for the 9MM and I understand the 147 gr bullets now stabilize just fine. My guns chew up 125 gr bullets just fine which is now what I shoot.

Take Care
