New Truglo sights shooting low and to the right

[zBernie]

I had a set of Truglo sights installed at a gun shop on my M&P9. When I test fired it at the rang I had target about 8 feet away and the group was low and to the right about 6 inches. It was even further off center at about 10 yards.

I took the gun back to the shop and he made an adjustment, but said the rear sight is windage adjustable only. Can anything be done if the gun is still shooting low?

-Thanks

Left handed by any chance?

That was my first thought as well, ATF

Were the truglo sights the same height as the originals ?

I've noticed that several after market sights do not state dimensions of the sight. If the replacement front sight is taller than the original,, or if the combination of front and rear are different ,, the point of impact is going to be different.

Had a guy I know that wanted night sights on his Springfield XD. I told him we would measure his sights and order. He didn't listen,, didn't measure,, ordered the sights,, paid big bucks. Had me put the sights on and when the point of impact changed a bunch ,, he was upset and acted like it was my fault..

S&W, Dawson, and others make, and state, dozens of different size sights.

ATF, my first thought too.

Ok assuming your sights are the correct height as Old & Slow mentioned the first diagram is for Southpaws and the second for the rest

Quick question, was the gun more accurate BEFORE the sight changes? The answer to this question will determine advice already given is valid, OR, you have grip, sight picture, and/or trigger control issues.

Here use this chart:

Don't get mad, I'm just kiddin'.............

No, right handed. Does that matter?

Yes, accuracy was good prior to having the sights installed.

You know I did not measure and just "ASSUMED" they were the correct height. They are specifically for an M&P though.

What sight picture are you using the sights elevation maybe set for the combat sight picture. Don

I've been thinking about it. I'm positive the sights I put on the guys Springfield XD was a Truglo Tritium Fiber Optic sights. ( a front & rear set )

Because, I had put a set of TFO on my daughters Glock and he liked them. They worked fine on the Glock, same point of impact , everything.
I'm pretty sure since they worked fine on the Glock,, he assumed a set for the XD would work fine too..

After he said his XD was shooting way low. I shot it and he was right. I found a rear sight that was the correct height, so he could at least keep the TFO night sight on the front.

Check out Dawson Precision. They have information on their web page about how to figure what sight height you need.

Can you measure the old sights and compare to the new? That would cover the low issue, but the low right is generally a LH shooter jerking or slapping the trigger, Or to much or too little finger pad on trigger.

That's why you were asked if you were lefty. Lefty tends to go low right and righty tends to go low left. It's almost always a trigger/user issue.

If you don't have access to measure old/new sights, then shoot from a rest or have someone else shoot the gun and see what results you get.

In your post #9, "specifically for an M&P" sights do come in different heights from different manufacturers. You could maybe shoot them an e-mail, or call and ask about heights as they may have a different height sets of the same style sights. As verified in post #11.

No, right handed. Does that matter?

Typically someone who doesn't shoot handguns on a weekly basis has a tendency for a push flinch, which causes the gun to shoot low, and a trigger snatch, which will typically cause the gun to pull left. So, for right handed shooters the Low and Left Syndrome is very very typical.

BTW, being right handed I have this problem anytime I go more than 2 weeks without shooting a handgun. As I've been spending all my range time enjoying a Match Grade AR I put together for my 60th last February I fully expect that I've got about 6 to 8 weeks of steady practice before I get to the point where my sights actually coincide with where my bullets hit.

Ha the manager at the range told me I didn't need to push the bullet would make it out the barrel on it's own. After that I quit shooting low. Because of a lot of dry firing and using the laser target system at least I wasn't shooting low left. Don

When I was having a problem, as I was trying to figure out what gives, BY ACCIDENT, I caught myself looking "around" the gun as soon as I pulled the trigger to "see where I hit the target"!

Once I caught that, I figured the hole was gonna stay there for a while and I quit doing it. But I still catch myself once in a while.

What a buffoon.

As stated before, it could. Printing low and right indicates a typical "trigger control" issue for a left-handed shooter, just as low and left indicates the same issue for a right-handed shooter. If you're left-handed, and printing low and right, it could be your technique as much as your equipment.

You're right-handed, so it's probably not the classical trigger control problem. There still may be something in your technique...it'd just be something different.

If the gun printed straight prior to the new sights, though, it certainly could be something with the new sights. If you are consistently low and right, you could drift the front sight to the right a bit and at least straighten out your windage problem.
