Anyone knows what is a near and far factory zero for most Glocks
like Glock 17/22 9mm, 22/23 40 cal?
Respectfully - if you don't know what those terms mean please do not respond.
To my knowledge the guns aren't test shot for any zero. They are only test fired for function and eve that is done in a "machine" thing that's kind of like a drawer. The gun goes in, goes bang a couple of times, then comes out. I believe any "zero" the guns hold is just based on the tech specs of the gun and sights ... not really a "zero" for that gun.
This is opposed to say, a custom 1911, that is accuracy tested and adjusted as necessary.
Might not answer your question per se but beats around the bush.
Perhaps the factory doesn't specify any particular zero in their manufacturing process however near and far zeros must exist.
Every firearm with any kind of sighting device, would it be iron sights or a scope has near and far zeros.
If Glock doesn't provide that information, perhaps someone empirically tested that with precision shooting from the bench.
From my experience near zero is probably at around 7 yards and far at around 35-50. But I might be wrong. I need a conformation to calculate proper hold offs for 100, 150 yards.
I am going to assume from experience in my shooting the near zero is 7 yards, dont know about far.
Here's a link to a "ballistics computer" that may help... It's not gun specific though.

Out to about 80 yards with my Gen 3 G23 I just put my target right above the front sight post. Fire.....wait about a second for it to get there[lol] and 'ting', it hits my gong.
