Big Dot on a Glock 19 with a laser under the barrel

[rational_behavior]

I have a Glock 19 with a "Big Dot" sight installed on the slide. If you don't know about Big Dots, basically, the rear is a shallow V with a thin line on the rear sight and front is a big "golf ball". To aim, you put the dot on your target, "dot the i" and pull. I like this system so far, as my needs with this gun are purely defensive. Recently, I added a laser that is attached by the rail underneath the barrel. My question is, are these two sighting mechanisms compatible? I fiddled with windage and elevation of the laser at the range a couple of days ago so that the laser was roughly were I was pointing at on a target at about 30 feet, while still "dotting the i".

What I discovered later is that at distances much less than 30 feet (i.e., inside my palatial 750 sq. ft mansion), if I'm "dotting the i" on my target, I can't see the laser because its blocked by my gun's frame. On the other hand, if I'm using the laser to target then the dot is way above the "i".

I'm somewhat new to anything other than the gutter sight on a revolver; is this what is meant by "sighting in a gun" to x distance vs. y distance? Or did I screw up the elevation already?

There is no use-case for this pistol outside of "get off me" and/or "get out" (of the aforementioned small house). Do I have to go back to the range and re-fiddle the laser at a shorter distance?

The "New Way" to zero a laser is at the "Furthest Distance" you can see your laser dot (generally at night) cowhitness your front sight to the center of your laser or lollypop/dot the I. What this does is make the narrowest point between your front sight and laser @ 1.5" at the widest and only get closer until you hit the apex where the 2 planes meet. The 1.5 offset will still give you A zone hits from 0 yards out to what ever your capabilities are at distance.
