I have not yet seen a laser that performs well for the wide range of conditions that might exist under an average hunting day, range included.

Under dim light and very short range conditions, some do phenomenally well with them on pistols, but such conditions are limited.

Maybe some day a gun will be designed around a high power laser sighting system that will perform well in bright light and at long range. We have not yet seen the ultimate development of such sighting systems.

But sighting aside, the biggest threat to hitting is the trigger squeeze. A laser doesn't make a good shot. A good shot makes good use of a laser.
