My wife has a SW .38 Sp J-Frame with a Crimson Trace LG-405 Grip Laser.
I had never messed with it much..but just tried to zero it with bore sight. The CT laser dot is about 4 in high and 2" left (all in garage without firing)
The windage adjustment was no problem...uses tiny hex wrench through hole in grip.
The elevation adjustment would not work. The actual adjustment screw is not visible as you work thru a time hole. Should work just like windage but nothing moves.
Anyone have any experience with this sight?
