FYI, I have reworked and updated some info on: "How you can get an automatic and correct Flash Sight Picture + ......"
And even when you can't see the sights or use them.
As a case in point, on 9/4 I was shooting at aerials (pop cans), and hitting them with a glock airsoft gun that I am not so fond of due to its bulky grip that I have cut down.
Shooting at and hitting aerials is not that hard. And doing it will make "normal" point shooting a breeze.
The point is that what is said in the article works.
Could it work for You? Don't see why not.
Here is the info if you are interested:
