Just saw this new style laser at a local store! The LaserLyte Rear sight laser only for GLOCKS! This may be my solution to finding a laser! Replaces the rear sight.. has an on off switch... has pulse AND contant beam... and best of all since it replaces the sight it has NO grip issues and fits ALL holsters!! Just what I was looking for!! VERY COOL!!!! Wanna kill these ads? We can help!
