I just recently got a glock 19 gen 2 from aim surplus and replaced all of the springs. It shoots fine but when I received it the rear sights were located as far right as they could go without going over the edge of the slide. I thought maybe someone was trying to compensate for a heavy trigger finger or something so I centered the sights and poi was too far to the left. I moved the sights back where they were when I received it and no problems.
My question is, what causes the glock's windage to be so far off? It doesn't seem like it would be an issue with the age of the barrel but maybe the manufacturing of the barrel or slide. I also just want to comment that I'm pretty surprised with how much a like the gen 2 frame compared with the gen 3. |

My bet is tolerance stacking. |

After reading other posts to find an answer I found a lot of comments about how it was the shooters lack of technique so I tried to be specific about it here so I wouldn't get too many of those comments. Thanks! |

Happened to me too with a Gen2 17. Was shooting fine for many, many years and then one day it was way off. Had to drift the rear sight all the way to one side.
A not-so-bright armorer at a GSSF match looked it over for cracks in the slide near the ejection port - wetting it with spit and trying to "bend" it enough to see a crack. Finding nothing, he took it out to the plates, missed the first few shots, then got on target but I could see where the POI was on the plates and it indicated that the rear sight still needed to go a bit more to the side. Since he was able to hit a plate, he declared the pistol "ok", never explaining why the rear sight had to be moved at all. 
So, I left it like that and haven't shot it since (I have many others). I'll get back to it someday. |

Think about all of the machining that has to be pretty much perfect in order for the sights to be "zeroed" while centered in the slide. The slide and barrel have to be perfect, the sights have to be perfect, the rear sight dovetail has to be perfect, and the hole for the front sight has to be perfect. There are tolerances on all of the dimensions, and if multiple dimensions are on one side or the other of the acceptable range, the rear sight may have to be drifted over to compensate. Happens from time to time. No big deal. If you can hit what you're aiming at, rock on and don't worry about it. |

From time to time my G20sf will shoot to the left. Next session it will be back where it belongs, center mass. I chalk it up to me and something that I am doing differently. No matter where it groups, the size is small enough that I am happy with it. I did move the rear sight, but then it would shoot to the right. On a good day when "I" was doing everything correct, I moved the sight back to where I figured that it should be. Most days at the range (back yard) it shoots well enough that I do not mess with it any more.
I shoot a lot of cast bullets through both a Lone Wolf and Storm Lake barrel, so I am not sure that it might be the bullets. They might be from a different batch, but not sure. |

Had the same problem with my Gen 4 G22 hitting way far left, and about 7-8" high at 25yds.
I dropped in a LWD barrel, which I was getting anyway for my reloads. A 6.1 height rear sight, and it now hits center. Sight that came with it was a 6.9 height. I think the barrel was poorly fitted to the slide on this one. |
