With current unavailability of ammunition & high prices when you do find it I am thinking a laser trainer might be a good idea. I've been looking around a little at the laser trainer systems. Has anyone here used Mantis X or any of the other systems. If you use something else & like it I would like to hear about it. If you use Mantis X & like it I would like to hear that too. Also if you have had a negative experience with one of these systems please reply. Most of the reviews I have found seem to be positive but more feedback is always good.
