I have 2 gnat's-ass questions about pistol sight pictures and factory zero distance.
1. At what range are factory Glock sights zeroed (assuming here that most/all standard-height aftermarket sights would follow suit if properly installed).
2. Within the sight picture at the zeroed distance, does the bullethole in the target bisect the top edge of the front sight post, or sit behind the post centered in the white dot? If the latter, at what range should I set the target for a properly-zeroed set of sights to show the bullet he bisecting the top edge of the front sight post?
Context: I just bought a used SIRT trainer on eBay and it's wildly off-zero. I'm trying to figure out what right looks like at CQB ranges so I can correctly practice in my garage.
