Cyber-terrorist Mai Linh carried the suppressed Heckler & Koch P2000SK pistol as her main sidearm.
Mai used the suppressed Heckler & Koch P2000SK around the Eastern Power Hub in Middleton, West Virginia when she and two other men arrived posing as FBI agents. Mai shot and killed one of the security guards with it. Then she fired a round from that pistol and killed the head computer operator at the central control room. She placed her pistol on the control console.
Later that night, John McClane and Matt Farrell arrived in the Eastern Hub. Then when they arrived in the central control room, McClane, pointing his SIG-Sauer P220 pistol at Mai, he prevented her from taking the P2000SK pistol. As he took from her, Mai fights back and gets her own pistol away from McClane. The P2000SK pistol was never seen or used again afterwards.
