Tijicon HD sights, Xs Big Dot sights, Meprolight, there are lots of choices out there, just comes down to what you like and will work for you and is easy to pick up with your eyes.. I have Xs big dots on my EDC G30SF, all my other glocks have stock sights, I just put a dot of high viz neon yellow paint on my stock sights to see them better over the white..
