Well there's no law prohibiting it, so that should mean it's legal.
Just make sure that the location of the mounted holster is such that the weapon is always under your control.
IANAL, but the only danger I could see from a holster in the center console (vs an under the steering column mount) is that depending on the location of the holster it could be argued that a passenger is the person "in control" of the firearm. Obviously this could pose a problem if your passenger was a minor or a prohibited person. Otherwise, it shouldn't be a problem. Just my 2 pennies.
