I wanted to get into a red dot optic for my glock (see my review for Trijicon Red Dot) but wasn't sure if I was going adopt this method permanently so I used this Glock mount and it is fantastic. Setup took a few minutes and I didn't have to modify my gun. If you really like the red dot concept on the pistol the best way to go is probably milling the slide so it will sit lower but I have no immediate plans of incurring the additional cost. I highly recommend this mount
Pros: Cost, ease of setup, go back to your old setup if you don't like it
Cons: Is going to sit high on the gun compared to other methods
