Eli5: Why do laser mounts of guns exist?

I understand that it makes you more accurate because it shows a dot where you are shooting. But dont they give away location and enemies know where you are shooting, thus they can flank you?

Generally speaking laser mounts are only used in very short range engagements. The beam of the laser isn’t usually visible, instead it is only the projected dot which is visible to the shooter (and it does provide a bright light from their position as well). A sniper for example wouldn’t want to use this because it would give away their position, be only vaguely visible from their range, and wouldn’t be pointed in the right direction anyway (being aligned with the barrel rather than the scope). That sort of thing is just for the movies where they need to show a gun is being pointed at a character without actually showing a view down the scope.

Instead lasers are used when relatively short range encounters are expected. Pointing a firearm at a target very quickly while under duress is actually somewhat difficult, especially when it is a pistol where there are tiny sights on the top to align. By using a laser sight pointing the firearm is basically as simple as directing a laser pointer: Put the dot on the target and the barrel is pointed in the right direction as well. Bullet drop isn’t relevant over such short distances so that is sufficient to indicate where the shots should strike.
