Sections 1 and 5 of the -1 and appendix A from -1-1 should help.http://publicintelligence.net/hellenic-air-force-f-16cd-flight-manuals/
Here is what I've come across
Aircraft operating weight 20,168 lbs (C model)
Maximum operating weight 48,000 lbs
Combat weight is usually 50% internal fuel and weapons for AA engagement. ~ 23,500 lbs
AA weapon loading depends on mission but I've seen mostly outboard-inboard 120-9-AG with some 120-120-AG. In an AA-only mission I've seen in order of decreasing likelihood: 120-120-9, 120-9-120, 120-120-120, and 120-9-9. I am very uncomfortable flying without an AIM-9 at all. If I am SEAD escort then I might bring only 120 since real escort has AIM-9 if a merge is required. In AG if I have to fire more than 2x120 then something is very wrong.
