I would suggest to practice in the dark or very low light. You also need to be able to see the threat such as a weapon in the hand. Then can you see your sights on your weapon and the target.
Good luck. Learning the hard way about this isn't the best way to learn
I let insects out of the house after I catch them, if possible.
That said, if someone would elect to pose a mortal threat to my family or me, they will die. End of story.
What if I have -really- freaking bright light mounted under my pistol?
Aiming’s not an issue...that’s what the laser’s for.
[the “blinding strobe” feature should be a hoot, too]
;D
