2-3mm at 7 yards should be easily corrected by bumping the rear sight about .003 to the right. I understand the op's desire that his pistol shoot straight but wonder if grip and stance might be affecting poi. Using myself as a sample of 1, I can say that 99% of my scores of handguns shot to the left unless I was shooting a revolver double action. The op might try shooting from a bench using a stable rest. If a friend has an aftermarket drop in barrel, he might try it to see if there's a difference.
I get what you're saying, but a very expensive vice was ultimately used (vice, not rest) which is a much more surefire way of checking, rather than human error introduction, and the vice replicated the problem as well as I did in regard to the amount that was being shot left. I did shoot it left handed from a rest and I got the same result as well.
Admittedly, I just threw those numbers out. I don't recall exactly the distance and amount it was being shot to the left (though I remember it being very little at closer distances), since it's been so long that all this started and I've tackled it bit by bit over the years. I guess I could center the sights perfectly on the slide again, shoot it from the vice, and record/post the data on here. It was recently when installing the red dot optic that I was reminded of it all and felt like making a post about the struggles with that particular specific Glock. Not being a gunsmith (or very smart apparently), it all made sense to me when I checked to see the slide/barrel fitment and saw how heavily the barrel leans and pushes to one particular slide. There is also a lot more barrel/slide wear on only ONE side of the barrel (towards the side it favors), further confirming the lack of proper slide and barrel alignment.
So tell me again why not just drift the rear sight a bit to the right and move on with your life? I’m not sure it’s worth all this.
Worth all what?
All the time you and everyone else took to type out this thread. It takes less time to drift a sight in a dovetail than to type the war and piece epic of your original post.
@HCM, do you have a way to verify cant on the front sight that you use, other than visually?
This thread has me wondering if there's a mechanical way to verify cant.
I am not @HCM but you can use a 12" steel ruler. Lay it along the side of the front sight and see where it aligns with the rear. Do it on both sides of the front sight.
This but with a small carpenter’s square.
