"I have never had a laser on any of my guns. I'm wondering if they are useful in conceal carry or home defense or if they promote bad habits and also, should new shooters use them?
I am not a new shooter but my wife is. "
I don't consider lasers to be anymore of a crutch than using night sights or a telescope on a rifle. My ultimate goal when picking up ane firearm is that I need to see the sights clearly enough to define the target involved. If that involves a target at 100yds or more, then I prefer a scope. If it involves a much closer target in low/failing light, I'm happy with either night sights or a laser. Of course, if I'm awakened in the middle of the night without my glasses on, then the laser is just the ticket for me. But, that's just me.
