Is it me or could it be the sights?

I just went and put about 100 rounds through an S&W M&P .40c. It consistently shot low and to the left when sighting the bullseye. When I shot high and to the right of the bullseye, I was able to hit the black and got a bullseye (at around 25 feet).

I don't know much about semi-autos, but it appears this gun has removeable rear sights. Could they be adjusted? Or is it my handling of the gun doing this?

Also, I had 3 ftf's through 50 rounds of Tul Ammo and none with Winchester white box.

I would have someone else shoot it, and see where they hit, before playing with the sights. More then likely, its you, not the pistol...

I'd agree,Its probably you and not the gun. Don't mess with it.

Start with you basic marksmanship skills, grip, sight alignment, trigger control etc.......

I'd guess that you don't have enough of you trigger finger on the trigger and are flinching or jerking the trigger. Get the trigger into the first knuckle's groove and pull the trigger straight back and to the rear. Don't let the gun rotate down as you pull the trigger.

As far as the ammo goes, some guns like certain ammo........

Keep shooting and see what works for you.........

Shoot the gun off a rest, or switch your grip as if your opposite hand was your strong hand, or have someone else shoot it. See where the holes accumulate. You'll probably confirm by any of these methods that it's not the sights.

It was weird. At 25 yards it seemed more accurate than at 25 feet.

I will try some of these suggestions, though. thanks

Sounds like the classic "jerk" or flinch which tends to pull your shots low and left if you use your right hand.. It is hard to convince most people that they have this problem because the recoil of the gun hides what they are doing. This is not an easy problem to overcome for most folks, especially on their own. If you have a friend who reloads, have him make you a few dummy rounds. Mix them with your live rounds and load your magazine without looking at which you are picking up. When you pull the trigger on a dummy round, you will be able to see what you're doing, and you'll probably be shocked at the degree of movement of your hand and arm when you pull the trigger.

It's the shooter. Don't adjust anything on the gun.

Smooth trigger pull. Proper stance. Forward lean towards target.

Thanks for the diagram. Seems I may be slap-happy on the trigger. :rolleyes:

I did some dry firing last night and I watched the muzzle carefully. There is definitely some movement up there when I shoot.

This M&P trigger is a different beast than I'm used to (revolvers). It doesn't really seem like you can "set" this trigger like others.

Get yourself a cheap laser pointer and use a rubber band to hold it to gun, a small piece of cloth will keep you from scratching the gun. Hold the dot on a light switch or something all the way through trigger pull.

...and you shouldn't be trying.

Trying to set or stage a trigger is what leads to a lot of slapping/jerking. Just press the trigger straight to the rear while watching your sights.

I just went through this with a client yesterday. We took him from a 6"-8" group at 5 yards (indoors) to a sub-3" group by tweaking his grip. Then we worked on his trigger press to get the shots inside an inch. We got his shots to drop on top of each other, by having him shoot DAO with my Kahr.

Getting him to just pull through the trigger was the key to accurate shooting

To find out if it's sighted in for you, sandbagging is better than offhand save if you're really good. Even if you're "really good", sandbagging is even more an assurace and essentially a failsafe proof of where it hits.. if you know what you're doing. If the shots are centered around the aiming point, it's sighted in.. if not, it is not. Drift the rear, change the front one way or another and or change load. Unless you're from Kentucky.

When I first bought my XDm, it was shooting low and left. I asked some questions, but before I tried seeing where I was going wrong, I had some night sights installed. Went back to the range and I was hitting dead on.

So it is possible its the sights. Have someone else shoot it to help you figure it out.

low-left is almost always a sign of jerking the trigger. Now that said, the 'trigger rose' that is posted above was designed for bullseye shooters, who shoot off-hand (one-handed). It still generally applies to two-handed shooting, particularly the trigger control pieces.

Get some sandbags and set the gun on the bench and shoot it and see where you are at. The bench is the only real way to remove most variables. Short of that, have an experienced shooter shoot the gun.

I rented a gun at the range one time where the sights were 12" too high at 9 yards. It does happen. But usually its the shooter.

This is why I did away with all my striker fired guns, save for my Kahr. Mushy triggers.

Are you exempting the Walther 99, Springfield XD/XDm and H&K P7?

Chris in VA could you elaborate on what you mean by "mushy" triggers? Nevermind, I think I understand what you mean. The revolvers I've been shooting have very crisp, tight triggers. These M&P ones aren't like that at all.
