I was looking around too.... Midway has one half, Brownell's the other half, so you can find what you need if you are OK with G19 and black. Nobody seems to have complete kit, and I think you need frame kit/jig, slide and frame parts kit (3 things). I've been looking around too... seems kinda pricey, as much or more that at the LGS.

I had a question about the legality of glock kits, but wound up just searching and finding the information myself. I must admit I was a bit surprised when I found out that full glock kits are legal to ship at all.
