The bishop - Laserlyte Fits Glock Handgun Rear Sight Laser Sight

I'm no gunsmith but with care and after carefully reading the instructions twice the installation went flawlessly. I took the pistol to the indoor range with a large target, and with some trial and error adjusted the laser red dot at point of consistent impact at about 25'. Since I wear bifocals I am now better able to put all the shots in a 1.5" circle. Paying a gunsmith to do it is another option for those who don't want to spend the effort. I would do it again. I love that all my holsters still fit the pistol with the Laserlyte attached.
Pros: ease of installation of hardware
Cons: adjustment of laser on target re: bullet impact
