I'm sorry, but I find most of this entire discussion hilarious. Red
point lasers are not intended to *illuminate* a target, if you mean by
that lighting it up. They are to tell you if you are pointing at your
human target, and not to the left or right of or above your target.
On a handgun, if you are shooting targets, a nice red dot sight like
this one...
With the right red dot sight, a good shooter with steady hands can place
his rounds precisely. The red dot is "projected" within the sight, not
onto the target. A good target pistol will easily accommodate a rail on
which you can mount a red dot sight.
You obviously have reading difficulties. The red spot indicates where
the bullet is going. No one said otherwise.
