In Episode 10, "Emperor and Hanged Man, Part 1", Hol Horse's Stand, The Emperor is a fictional revolver seemingly based on the LAPD 2019 Blaster, with the pistol grip based on the CZ-75, capable of materializing at will and manipulating projectiles mid-air. The Emperor later appears in Episode 11 ("Emperor and Hanged Man, Part 2"), Episode 14 ("Justice, Part 1"), Episode 15 ("Justice, Part 2"), and considerably later in Episodes 36 ("Hol Horse and Boingo, Part 1") and 37 ("Hol Horse and Boingo, Part 2").
In Episode 12, "The Empress", Indian police use revolvers; while they are not seen clearly enough to make a definitive ID, context makes the most likely option the Enfield No. 2.
In Episode 32, "Sethan's Alessi, Part 1", Alessi wields a Stechkin APB with a non-standard underbarrel rail and suppressor. He fires it eight times, then re-holsters it and never uses it again.
In Episode 47, "DIO's World, Part 3", Nukesaku uses a Sawn-off Double Barreled Shotgun of unknown make and model to test the power of DIO's Stand, The World.
In a continuity error, the Egyptian police officers' sidearms turn into Glock 18C machine pistols, colored as though they had wooden grips. In one particular shot, one of the pistols visibly has a thumb relief cut into the frame, making it a third-generation model, and thus anachronistic (as Stardust Crusaders takes place in 1987, when Glocks would have still been in their first generation).
