You'll love this. I have a Quick Disconnect Laserlyte. I carefully shot at 15 feet using my range bag as a rest (old briefcase). I aimed the light at the center of an N.R.A. pistol target. The shots were at about 5-6 inches to 9 o'clock. When I got home, I took the laser off the gun and put it on a table at about the same distance. I then taped the target on the living room wall with the dot in the center of the target. Holding the laser steady, I moved the dot to the center of the group using the Allen wrench. I re-mounted it on the gun. To quote that famous T.V. cop, Hunter. "Works For Me".
