Luger P08

Alpha (Anthony Dawson)gives a Luger to Gamma (Mario Soria) and orders him to commit suicide. Gamma instead turns the gun at Alpha, only to find out that the gun is empty and that the water he drunk earlier was poisoned. Maya (Daniela Bianchi) kill an assassin, who tries to kill Connery, with a silenced Luger. During the final battle inside the THANATHOS base Juan (Franco Giacobini) also carries a Luger, which briefly turns into an Astra 400 Kurt (Guido Lolobrigida), Thair's henchman, also carries a Luger.

Note: Both Gamma's death and the scene where Maya shoots the assassin were cut from the MST3K version because of time constraints.

Astra 400

THANATHOS uses a device, that makes all mechanical object useless. Thus the guards at the base and the agents storming the base all have bows or spear guns, except Juan who has a useless Luger. The Luger however turns into an Astra 400 at one point.

Colt M1911A1

When the agents attack the THANATHOS villa Juan uses a Colt M1911A1, and he shoots Mildred (Agata Flori), who also has the same type of pistol. Earlier the guard who looks after Yachuko also has a Colt. Later Connery also has a Colt, but he gets disarmed before he can use it.
