From what I've read, the lasers really are worth getting for better accuracy.
Oh, and an added benefit. Apparently, when the focus is right, the lasers can be a compelling argument for a criminal to decide to depart the scene.
You won’t regret your decision. I love my CT lasergrips.
The only drawback is when practicing. In full sunlight, they don’t show up well on a target, unless you are really close; which is why I live fire on overcast days when I can.
For dry fire, low light, or if you have an opportunity to shoot indoors, they are excellent.
FWIW, one time I had to use my Smith w/ CT in a situation. A 6’5” man was attacking me. When I aimed at his forehead, at about 10’ range as he was coming for me, I said, “And I know how to use it.” He immediately hit the ground and begged for mercy.
The long and short of it is, I firmly believe the laser was what stopped him in his tracks; he might have continued toward me, and tried to take the gun away from me if it wasn’t for the red dot.
The groups I shoot with it are great, much improved from when I was just using the sights. And as my eyes are getting older, I just don’t see as well; add to that a panic situation and lasergrips give you an added advantage that could be life or death.
Your mileage may vary. ;-D
