situations in which one can not readily index on the target in other ways, e. g., shooting from behind cover or unconventional positions in which one can't get a sight picture.
"Fun and Games with CT Laser sights"
When I was in LE I did a heck of a lot of building searches. I use to carry a little inspection mirror for peeking around corners and what not.
Didn't have LSs back then (or I didn't know about them). I don't do building searches any more but I still like using the mirror.
On my private range, I get behind the barricade, poke the gun around the barricade without exposing my head, then use the mirror to sight the red dot on the target.
Lots of fun, after a while you can get pretty good. Just remember using the mirror you move the dot opposite of what you think. Try it some time, Challenging at first but like I said, lots of fun.
