If you are looking for something like a Blackhawk Serpa, get the one that is marked for the H&K P30. There are people that are against using the Serpa style holster, but if it is for the range only, and that is what you are going to train with, I do not have a problem with mine. It fits the FNX9 just fine. I suspect that a lot of the "fitted" holsters for the P30 will work for the FNX9.
