A Beretta M951 is used by Avner (Eric Bana) and Steve (Daniel Craig) as their personal weapons throughout the movie. Robert (Mathieu Kassovitz) also uses a Beretta M951 during the assassination of Abdel Wael Zwaiter in Rome, though he later switches to a Walther PPK.It should be noted that Avner brandishes Beretta M92F on the DVD cover, which would not have existed in 1972.
Note: The actual Mossad assasins used surpressed Beretta Model 70 pistols with hollow points.
I believe the real pistols were .22s. And in the movie, there are .22LR casings lying in the pool of the first target's blood.
Walther P38 or post-war P1 pistols can be seen in the hands of Palestinian terrorists throughout the movie, most notably during the initial seizure of the Israeli athletes in Munich and later during a Mexican stand-off between the assassins and PLO operatives in Athens. It should be noted that in real life, the Black September terrorists used Tokarev TT-33 pistols rather than the Walther.
Walther PPK pistols are used by members of Avner's team and by Palestinian terrorists, most prominently during the scene in Athens where the PLO operatives and Israeli assassins find each other sharing the same room. Later, Ali (Omar Metwally), uses a Walther PPK during a shootout with Avner as the assassins try to flee the scene after killing Zaiad Muchasi.
A Makarov PM is used by Carl (Ciarán Hinds) and Robert (Mathieu Kassovitz) during the scenes set in Athens, a curious choice considering the weapons used by his fellow team members. A Makarov is also carried by a KGB bodyguard that is watching over Zaiad Muchasi.
Jeanette (Marie-Josée Croze), the Dutch assassin that the team hunts down after Carl's death, attempts to reach for a Beretta 950 Jetfire before being shot by Avner and Steve's zip guns.
Norinco Type 56-1 rifles, distinguished by their hooded sights and underfolding stocks, stand in for the AKS-47s that were actually used by the Palestinian terrorists during the hostage crisis at Munich. Israeli Sayeret Matkal commandos also use Type 56-1s their raid on the PLO compound in Beirut.
An Israeli-model FN FAL fitted with a scope is used by Avner (Eric Bana) and Steve (Daniel Craig) when they attempt to assassinate Ali Hassan Salameh in Spain.
Heckler & Koch G3 rifles are used by the German police that surround the apartments where the Israeli hostages are being held, and later during their botched hostage rescue attempt at the airfield. Though the rifles used during the hostage rescue attempt are modified to resemble G3A3ZFs with 4x scopes, the police marksmen in real life used G3 rifles without telescopic or night vision devices.
WWII-era white phosphorous grenades are part of an explosive device assembled by Robert to kill Zaiad Muchasi in Athens. When the device fails to go off as planned, Hans (Hanns Zischler), the assassination team's document forger, uses another white phosphorous grenade to initiate the device, leading to a shootout between Muchasi's guards and Avner's team.
"Issa" (Karim Saleh), the leader of the attackers at Munich, uses a Soviet F1 fragmentation grenade to destroy one of the helicopters with the Israeli hostages after being ambushed by German police at the Fürstenfeldbruck airfield.
