Mackey goes to the Byz Lat compound to interview Santi. The gang tells him to give them his pistol, which he refuses. He drops the magazine at 22:03 and asks if an empty gun is OK, and they let him in. At 23:42 he threatens Santi with the pistol, saying he still has a round in the chamber. Problem: all metal-framed Smith and Wesson semi-automatics, including Mackey's 4506, have a magazine safety. At the time he dropped the magazine, Mackey had a pistol that was incapable of firing unless he first inserted another magazine.
