I got my first Zookeeper holster last weekend. CB came through with a holster that was exactly what I asked for. It is holding my Glock 19 right now, but I got him to leave the muzzle end open and the sight channel open large enough to accommodate models with a longer slide, like the 17 and 34. The quality of material and workmanship is excellent, and the truly custom service provided by the zookeeper is second to none. I highly recommend his product and service.
