I've been a huge Glock fan since the day my oldman gave me his duty Glock 23 after he retired as a Detective from the Milwaukee Police Department. I just picked up a Glock 20C with night sights I scored from a local Gun shop. At $450 I could not go wrong. It was used but you would never have known it by the new condition. I was searching upgrades when I found this sight. Thanks for the good insight thus far....
