I recently bought a BlackHawk CQC SERPA holster for my Glock 20 after recommendation from my local gunshop, the owner which happens also to be a police officer. I have to admit, its the best holster I have ever used. I like the side release latch button on the side of the holster. My Glock 20 snaps in and stays put until I release the latch button; it fits like a glove, too! Highly recommended!!!
