Part 2: Battle Tendency
Colt Official Police
In Episode 10 ("New York's JoJo"), one of the two New York City police officers wields what appears to be a Colt Official Police revolver.
Webley Mk VI
In Robert Speedwagon's flashback in Episode 10, one of the hijackers onboard Speedwagon's airplane wields a revolver, seemingly a Webley Mk VI.
M1A1 Thompson
The other two hijackers use M1A1 Thompson submachine guns without handguards. Seeing as this scene takes place in 1933, the M1A1 is anachronistic.
M1928 Thompson
At the end of Episode 10 and the beginning of Episode 11 ("The Game Master"), Joseph Joestar uses an M1928 Thompson submachine gun with a 50-round drum magazine against Straizo.
Mk 2 hand grenade
After failing to kill Straizo with his Thompson, Joseph uses several Mk 2 hand grenades against Straizo.
8.8cm FlaK 36
During Episode 11's explanation of World War II, German soldiers are seen firing an 8.8cm FlaK 36 anti-aircraft cannon.
Karabiner 98k
In Episode 12 ("The Pillar Man"), two of the German guards outside the secret facility in Mexico use rifles; while they are not particularly detailed, their general features (and the context) make the most likely choice the Karabiner 98k. Later on in the same episode, another guard inside the facility uses a similar rifle.
MP40
The majority of the German guards inside the secret facility use MP40 submachine guns. Santana also takes one and disassembles it in Episode 13, "JoJo vs. The Ultimate Lifeforms". As this scene takes place in 1938, they are anachronistic.
Walther P38
One of the guards inside the secret facility uses a Walther P38 pistol.
Rudol von Stroheim has a collapsible machine gun of apparently fictional design in his torso in Episode 19 ("A Race Toward the Brink"). According to Stroheim, it fires at 600 rounds per minute, and is capable of piercing 30 millimeters of steel. After this episode, it also appears in the ending sequence.
Vickers Aircraft Machine Gun
In the exposition sequence in Episode 24 ("The Ties That Bind JoJo"), George Joestar II's biplane is fitted with a pair of Vickers Aircraft Machine Guns.
MG17
In Episode 25 ("The Birth of a Superbeing"), the seaplane that Jonathan steals is fitted with a pair of MG17 machine guns, which he uses against Kars.
Rudol von Stroheim's Weapons
In Episode 26 ("The Ascendant One"), Rudol von Stroheim is seen in Stalingrad with a variety of weapons, listed below.
Part 3: Stardust Crusaders
Nambu Model 60
In Episode 1 ("A Man Possessed by an Evil Spirit"), Japanese police officers carry the Nambu Model 60. Jotaro Kujo also takes one of these revolvers.
The Emperor
In Episode 10, "Emperor and Hanged Man, Part 1", Hol Horse's Stand, The Emperor is a fictional revolver seemingly based on the (Blade Runner) - 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"), and Episode 15 ("Justice, Part 2"). In Season 3, he also uses it in Episode 12 ("Hol Horse and Boingo, Part 1") and Episode 13 ("Hol Horse and Boingo, Part 2").
Enfield No. 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.
Colt 1851 Navy
In Episode 14, "Justice, Part 1", the dead man seen at the beginning of the episode holds a Colt 1851 Navy revolver.
Stechkin APB
In Episode 8 of Season 3, "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.
Ithaca 37
In Episode 12 of Season 3, "Hol Horse and Boingo, Part 1", the man escorting a woman through the desert carries an Ithaca 37 shotgun. He is never seen using it.
Sawn-off Double Barreled Shotgun
In Episode 23 of Season 3, "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.
Browning Hi-Power
Later on in Episode 23, Egyptian police officers are seen using pistols resembling the Browning Hi-Power, albeit drawn somewhat inconsistently.
Glock 18C
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).
Part 4: Diamond Is Unbreakable
Nambu Model 60
In Episode 2, "Josuke Higashikata! Meets Angelo", Ryohei Higashikata uses a model Nambu Model 60 to intimidate his grandson Josuke.
Colt M16A1
The soldiers of Keicho Nijimura's Stand, Bad Company (appearing in Episode 4 ("The Nijimura Brothers, Part 2") and Episode 5 ("The Nijimura Brothers, Part 3")) wield Colt M16A1 assault rifles.
M67 hand grenade
Bad Company's soldiers also have M67 hand grenades on their webgear, though they are never seen using them.
M230 Chain Gun
The AH-64 Apache helicopters used by Bad Company have 19-barreled Hydra 70 rocket pods and AGM-114 Hellfire missiles on their wings, and M230 Chain Guns on their chins.
Browning M2HB
The M1 Abrams tanks used by Bad Company have Browning M2HB machine guns mounted atop their turrets.
M240
Bad Company's M1 Abrams tanks also have two M240 machine guns on each of them, with an M240C mounted coaxially and an M240D on top of the turret.
In Episode 12 ("Red Hot Chili Pepper, Part 2"), Akira Otoshi's Stand, Red Hot Chili Pepper, takes control of a miniature R/C Supermarine Spitfire in E-wing configuration, fitted with two non-functional Hispano-Suiza HS.404 autocannons.
Browning M2 Aircraft
The aforementioned model Spitfire is also fitted with two non-functional Browning M2 Aircraft machine guns.
Beretta 92F
In Episode 33, "July 15th (Thursday), Part 3", Terunosuke Miyamoto uses a Beretta 92F against Josuke. He fires the pistol once, then discards it.
Part 5: Vento Aureo
Smith & Wesson Model 30
Throughout the season, as well as in both openings ("Fighting Gold" and "Traitor's Requiem") and both variations of the first ending ("Freek'N You"), Guido Mista carries a custom Smith & Wesson Model 30 revolver, with a purple finish and a hammer shroud reminiscent of the Smith & Wesson Model 49 (albeit depicted as a separate part). He notably uses the weapon in combination with his Stand, Sex Pistols, to aid in reloading the weapon and redirect bullets mid-air.
LAU-68
Narancia Ghirga's Stand, Aerosmith, seen throughout both openings, both variations of the first ending, all variations of the second ending ("Modern Crusaders"), and most of the episodes in which he is present (starting in Episode 9, "The First Order from the Boss"), is a miniature airplane, armed with a chin-mounted bomb and two wing-mounted LAU-68 rocket pods, incorrectly depicted as multi-barreled machine guns.

Colt Combat Commander
Polpo's cell contains a stash of forbidden items, one of which is a Colt Combat Commander pistol. Another handgun is also present, though it is not seen clearly enough to make an ID.
Smith & Wesson Model 29
The stash of forbidden items in Polpo's cell also contains a Smith & Wesson Model 29. Notably, in Episode 4, Giorno uses his Stand, Golden Experience, to turn this revolver into a banana, causing Polpo to shoot himself upon attempting to eat it.
Mk 2 hand grenade
Another weapon in Polpo's stash of forbidden items is a Mk 2 hand grenade.
Colt M1911A1
A gang member discussing Polpo's death is seen using what appears to be a Colt M1911A1 in Episode 5, "Find Polpo's Fortune!"
