A Glock pistol is used by both Khalid (Ali Kazim) during the gas station robbery and later by Neo-Nazi leader Esben (Lars Ranthe) when threatening Ivan (Mads Mikkelsen). Probably a Glock 19.
Vektor SP1 Pistol
The Vektor SP1 also has multiple appearences on the screen. First, Adam (Ulrich Thomsen) draws it when presenting it as a "solution" for the crow plague. Later, Khalid (Ali Kazim) fires it, wounding some of the Neo-Nazis, and later, during the gas station robbery, it is again carried by Adam.
Unidentified Pistol
Khalid (Ali Kazim) uses this to shoot the crows. It is never shown in more detail than in these few scenes. It is clearly different from both the Vektor and Glock pistols.
Unidentified Revolver (Astra 960?)
Before the robbery, Gunnar (Nicolas Bro) is armed with an Unidentified Revolver, which is never seen closely. Might be an Astra 960.
Unidentified Sawed-Off Shotgun
During the gas station robbery, Khalid (Ali Kazim) wields an Unidentfied Sawed-Off Shotgun.
SVD Dragunov
While preparing the gas station robbery, Khalid (Ali Kazim) fires and unloads a SVD Dragunov (without scope), which is shown only in two short shots. Might also be a SAIGA 308.
