DeerPredator, there are those who would call you paranoid for carrying three guns...but, heck, a lot of them would call you paranoid for carrying ONE.
Be able to articulate the reason(s) you chose to carry three guns, and to document that there are experts who agree with you. In the pages of Guns and American Handgunner, Clint Smith has mentioned that he carries a backup gun, and sometimes two. John Farnam has explained to students, and to readers of his DTI Quips and his books, that he commonly carries more than two handguns.
Your setup is well thought out. Service pistol readily accessible to dominant hand, on hip. Small backup in weak side pocket gives fallback if dominant arm is hurt, and also allows you to discreetly have hand on gun in an "iffy" situation. Ankle holster is ideal when seatbelted behind a steering wheel, or down on your back.
Definitely pick up a copy of "Armed Response" by Dave Kenik, a concealed carry and self-defense expert who posts frequently on GlockTalk. In it, among other things, he gives a very lucid explanation of why he carries a primary on the hip, a BUG in a pocket, and another BUG on the ankle.
David Kenik also gives the coolest response I've ever heard to those who think carrying more than one firearm goes overboard. When asked why he carries three handguns, he replies, "Four would be ostentatious."
On a more serious note, check local regulations. At least one Federal agency forbids its armed personnel to carry more than one handgun, on or off duty. The state of New Mexico allows the licensed private citizen to carry only one handgun on his or her person in public.
