In Day 5 of 24, after living under an assumed name, Jack Bauer returns to Los Angeles CTU when a close friend of his is assassinated and Russian separatists threaten to carry out attacks throughout the United States if an anti-terrorism peace treaty between the US and Russia is signed.
The following weapons were used in Season 5 of 24:
Jack Bauer (Kiefer Sutherland) continues to use a Heckler & Koch USP Compact, chambered in 9x19mm, in Season 5 of 24. He is seen using it with and without a suppressor. Wayne Palmer (D.B. Woodside) is seen holding the USP Compact on Jack in "8:00am-9:00am" (S5E02). Christopher Henderson (Peter Weller) is seen holding Jack's USP in (S5E10).
TRIVIA: There were only two H&K USP Compacts used by Kiefer Sutherland through the entire run of the series. This was because Kiefer is a method actor and did not like to change props. 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.)
TRIVIA: Kiefer Sutherland also used the gun pictured above during the photo shoot for one of the posters promoting Season 5 of the series. 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.
