The vampires that try to capture Blade (Wesley Snipes) at the FBI Headquarter are armed with AP-9s, a gun built by AA Arms/Kimel Industries and is commonly confused with the Intratec TEC-9/DC-9s. Danica Talos (Parker Posey) also uses a satin nickel version of the AP-9 when she is shooting at Abigail (Jessica Biel) on the catwalk at the end of the film.
