I'm not Air Force - however I can assure you that none of the three you mentioned would be used.
The standard issue firearms remain the M16A2/A4 rifles and the M9 (Beretta 92FS) pistol. I have seen the M4 used for qualifications in lieu of the M16A2/A4. A few select AF units use the M11 (Sig P228) instead of the M9. For your purposes, however, you should probably be thinking M16A2 and M9.
