He only wore 3 real kevlar bullet proof vests through out all 8 seasons. (IMFDB thanks The Golden Closet for providing the documentation on this gun.)

Because it was technically a live firing weapon and the photo shoot took place in Washington DC on the steps of one of the monuments, Secret Service agents were required to be present at the photography session.
