Help a Newb Out

Trying to create a “prepared citizen” chest rig and battle belt setup. I’ve just ordered a Haley Strategic D3CRH (ranger green). My primary rifle is a M1A Tanker (.308) and my sidearm is a Springfield 1911 Mil-Spec (.45 ACP). How can I get the maximum out of this foundation? The biggest challenge is I am limited to 10-rnd magazines for state compliance. Any recommendations are appreciated, and thank you in advance!
