So everyone out there is not over forty years old and has perfect eye sight and does not wear bi-focals. Those are some of the cases where lasers really help. How much gun smoke is there in a defensive shooting scenario?
was interested in lasers until I used one in a low-light, indoor shoot a while back. We were doing a 2-man drill, and after just a few shots were fired, the laser did a great job of lighting up the smoke but not the target. The other problem is that without a lot of practice there is a natural tendency to chase the dot and not the target.
IMO they're a great training aid, but I'm not saving up for one.
