G19/23 Point of Aim or Zero Out of Box

OK, we all know that the standard Glock is not "zeroed" in the factory. The test fire is just function check. But here is my question.

A conversation with some friends brought this up even though we all change out for aftermarket, we are curious. Is there intent in the design for the sights out of box to be set at a certain distance?

A standard Out of the Box G19 or G23 (actually it would be interesting for all models and Gen's) with factory sights (no optics) what is the rough point of aim/impact distance?

We figure the design itself, based on the dimensions of the pistol and height of the sights there would be an "expected zero distance". With manufacturing I would assume some sort of consistency in sight installation. So, where is the "expected" zero distance based on the dimensions, sight height, etc.? Of course different ammo as well as bullet weights, etc. would change this. But we would assume the engineers involved would have had some sort of intention around this. 5 yards, 7, 9, 20, 25, 50? Or even what people have seen on the first range trip. I plan on trying to get anyone I know to start tracking to compare. :)

I hope that made sense. Also, factoring in that it is not done purposely you would not rely on it as a true zero by any stretch.

Thank you for that information. Very interesting. A lot of this conversation came from how a few of the guys were getting good grouping out to 15 yds (3-4 inches) but as soon as they tried 25 yds they were not hitting paper. Most of the guys were teasing about their horrible shooting. Much more colorful words where used. LOL

Complete geeking out below and in denfensive shooting would make little difference for most people but interesting.
I may be completely over thinking it. But that variance (2.4 inches for each rear sight and 3 changes) you have a possible barrel angle variance of ~20+ degrees. Used fuzzy off the top of the head math. Where your example above is "assuming" a 0 degree variance. That the barrel is parallel to your line of sight. But changing the rear sight you are basically mortaring your barrel. It is canted several degrees upward from your line of sight. Regardless of the math, the idea is that there could be circumstances (specific handguns) where you could get decent groups out to 15 meters/yards (the shooter will notice the POI is a little higher than POA. But reaching out to 25 meters/yds you could end up off paper and have to hold over. Or am I up in the night? Complete off the top of my head with very little to no math involved.

Regardless, I appreciate you entertaining my crazy question on the engineering and design.
