NYPD Captain Roy Montgomery was Kate Beckett's boss at the Twelfth Precinct's Homicide Division. He carried a .38 Colt Detective Special as his sidearm, which he pointed at Dick Coonan during the latter's aborted escape attempt from the Twelfth Precinct. ("Sucker Punch") In the two other instances where he is seen with a gun, however, he used different revolvers; in "Murder Most Fowl", he carried a large-caliber revolver in a stainless finish, but in "Knockout", during his last stand against Hal Lockwood and his forces, he carried some kind of large revolver in a gunmetal finish and had a two-barreled Derringer pistol as a holdout weapon held in his left sleeve.
