Paris police Detective Hubert Fiorentini (Jean Reno) carries a Smith & Wesson Model 686 as his service sidearm. During his confrontation with the leader of the transvestite bank robbers, Irène (Alexandre Brik), he kicks it over to Irene without the latter knowing it has been unloaded.
SIG assault rifles
The Paris police are seen with SIG assault rifles outside the Banque de L'Etoile.
FN Browning M1905
Irene (Alexandre Brik) holds a FN Browning M1905 on the bank president before carelessly tossing it aside when he gets ahold of Hubert's Model 629. Hubert mockingly tells Irene that the M1905 looks like a device used for ear-piercing.
Desert Eagle
A black Desert Eagle is among the many weapons Momo presents to Hubert upon his arrival in Japan.
Beretta 92FS (Two-tone)
Two two-tone Beretta 92FSs are visible inside one of the suitcases Momo presents to Hubert upon his arrival in Japan.
Mini Uzi
A Mini Uzi is visible inside one of the suitcases, which Momo describes as the "latest Uzi", firing "50 rounds per second". A Yakuza thug during the bank standoff also carries one.
M72 LAW
Momo provides two M72 LAWs for Hubert, telling him they are "heat-seeking rocket launcher[s]... 400 grams each... I got two." Although never seen, Momo also claims to have obtained an "anti-personnel miniature bazooka made in Korea" that "stops a tank at 100 yards".
"compressed air missiles"
Momo also provides "compressed air missiles" for Hubert that can "rip out a tree at 50 yards" for "maximum efficiency".
Mk 2 hand grenade
Momo (Michel Muller) carelessly tosses a Mk 2 hand grenade around after retrieving it from the suitcases he got for Hubert. He later realizes that the pin is out when he "saves" Hubert at the driving range, causing the two to run for cover as their car explodes.
"mustard gas launcher"
Momo also carries a "mustard gas" launcher inside the cases he brings to Hubert.
Momo (Michel Muller) also carries a Beretta Cougar Inox inside the cases of weapons he brings to Hubert. Momo also carries one alongside his SIG P226 after the arcade shootout. A Yakuza thug carries two.
Smith & Wesson Model 66
Momo (Michel Muller) brings two Smith & Wesson Model 66 revolvers for Hubert including a heavily-modified model that he demonstrates for Hubert. A Japanese Intelligence officer also carries one during the bank standoff.
Hubert (Jean Reno) picks out a Taurus Raging Bull from Momo (Michel Muller). After the bank shootout (during which the Raging Bull inexplicably made people fly across the room when they were fired upon), Momo picks up Hubert's discarded Raging Bull and waves it around at the dead Yakuza members. Hubert identifies the revolver as a ".45" when talking to Takawana, meaning that it only has a five-round capacity (despite the seven shots he fires from it without reloading during the arcade shootout).
A Yakuza thug holds a Glock 17 on Hubert and is also disarmed by a golf ball.
Beretta 92FS
A Yakuza thug draws an all-black Beretta 92FS on Hubert but is quickly disarmed by a golf ball. Hubert (Jean Reno) himself carries a Beretta with a light during the bank shootout after his Raging Bull runs out of ammunition.
