I would like to adjust the rear sight a little bit to the right. What is the technique to do it correctly? This is on a glock 17.
Thanks.
 
Glock rear sight adjustment tool,push in the direction you want to move the point of impact, that's the correct way. You can do it carefully with a drift punch and light hammer

If you use a drift punch, make sure it is brass and you place it as low on the sight body as possible. Back in the day I broke a sight trying to drift it. Place the gun in a vise with padding so it will not be moving. Better yet acquire a sight tool, as Strike suggests.
 
If your Glock is shooting to the left, (and you are right handed) it is very possible that you are squeezing the three remaining grip fingers on your right hand as you pull the trigger. This will cause the pistol to move ever so slightly to the left.

To test for this, hold up two fingers on your left hand upright as if simulating a pistol grip. Grasp those fingers with your right hand just like you would grip your pistol. Now, simulate pulling the trigger with your right trigger finger. The vast majority of the world will notice the tendons in their right palm tightening while you simulate pulling the trigger. This causes you to slightly roll the pistol to the left while shooting.

This is NORMAL as our hands are designed to grasp things using all fingers together. So, pulling a trigger, and expecting none of the other fingers on that hand to tighten along with the trigger finger isn't the way we are made. The solution it to practice exercising your trigger finger with as little movement in the other fingers as possible. Over time, you will get much better at separating out the tendency of working together.

It is sort of like trying to do that Mr. Spock finger split thing without practicing it first...our hands just aren't designed to do that, they have to be trained.
 
Thanks unknown. I tried that and may have had some of that ancillary pressure. Or I may have been thinking about it and thus not applied it. I practice issolating trigger control through a lot of dry fire so hopefully I would not have that tendency. Why not just adjust the sight and as long as I stay consistent it would be ok?
 
Adjusting the sights to compensate for an error that could be corrected doesn't seem to be a good idea to me. Knowing about this tendency is about half the way to solving it. If you adjust your sights to compensate, then every other pistol on the world that is properly zeroed will shoot to the left for you.

Fixing the issue means that most pistols will shoot well for you. If you ever pick up a strange pistol, it would be nice to think that it will probably shoot well for you, otherwise, there is only one pistol you can hit reasonably well with. A fixed sight gun would be fairly worthless to you unless you fix the issue. I would prefer knowing that most guns will hit where I aim them.

I think fixing problems or bad habits is a better idea than adjusting your shooting style to accomodate those bad habits. Overall, fixing the issue will give more rewards than adjusting your pistol to accomodate the problem.
