Sight Adjustment

[Styx]

I have a two part question. I recently had night sights installed on my Beretta APX by my LGS a few days ago because I had trouble installing them myself. I took it to the range today and now the gun shoots slightly left. For those who purchase a new pistol or have a gunsmith install aftermarket sights, do you typically just live with it and change your hold a tad bit to the right to compensate?

On my Walther PPS M2 that I installed the sights on, the gun is shooting far to the left. How do I go about remedying this? Do drift the sight to the right?

I should note that I didn't have any issues with the APX with the stock sights. As far as the PPS goes, it's been a long time since I fired it, but I don't think it's me. I'm pretty sure it's not.

Move rear sights in the direction you want to move the group. In such a case I would drift it with sight pusher or a suitable brass drift in small increments, then test. For a gun that is shooting low, one method of correction is to reduce the height of the front sight to raise the group, either by replacing it with a shorter sight or filing it in small increments until you have the desired POI (presuming it has a non-adjustable rear sight).

In my case I can live with variations in elevation because different grip pressure, loads and distances will cause this to vary regularly, but if windage is off by very much and this was consistent across a variety of loads, I would want to move the sight to center up the group.

As long as the front sight is centered in the dovetail (assuming thats how its installed) just drift the rear to the right a little.

Its not unusual to have to make minor adjustments the first time out when new sights are installed. If you dont want to do it, you could ask the shop to do it.

Thanks you two. This is my first time having this issue. Just wanted to make sure.

So if I'm understanding correctly, I should move the rear sight to the right, correct?

Correct.

You can do it two ways to. Go easy, and drive yourself nuts, going a little at a time.

Or go a little more than you think you should, and then come back. You can use a pencil to make a witness mark to help you gage things.

I have a tool, and just usually crank past it, and then come back. Im not a fan of beating on night sights with a punch. Especially if they are really tight.

Had this problem with my used SIG 226, after testing several brands and grains of ammo they all shot to the right of the bulls, last Sunday I took it out with my brass hammer and punch set and tapped the rear sight until it shoots dead in the center. As others have said, to move impact to the left, move rear sight to left, or visa versa and or move front sight opposite.

Put your hands up make a V with one and a post with the other imitating sights, move your V hand and then adjust your post finger to center and you will see.
