Also, as with DJ Niner, I have the LaserLyte Glock RSL rear sights, but I'm happy with mine. As he said, it's not real quick to turn on, but with practice, I find it acceptable. I paid less than $80.
Thank you so much for the info. I'll put it to good use. This sight has been so helpful for me so far...
