Laserlyte rear sight for glock 27 - Laserlyte Rear Sight Laser For Glock 59474

The Laserlyte rear sight laser is an excellent choice. I have had mine for almost 2 years. It stays set very well. I have often shot a quarter size pattern at 20yds consistently. The only issue I have had is I recently lost the battery cover. I contacted Laserlyte, and they are sending me a new one free. Very good company to deal with.
Pros: Does what it suppose to do. Set it in, place the laser dot and hits target every time.
Cons: Need to keep battery cover extremely tight. I lost mine.
