CCI Blazer Brass is good stuff. Fairly clean ammo that is either the same price as WWB or just a little cheaper. CCI also make plain Blazer, which is aluminum cased. The plain Blazer goes for cheaper and I have heard good stuff about it, just never personally shot it since the brass was just a dollar or two more and was sold at Walmart. If you look though, the casings that came with your G19 should be CCI Blazer Aluminum, so clearly it is decent stuff that feeds well enough if Glock themselves are using it for demo shots.
