Atomic Blonde is a 2017 American spy thriller set in 1989 Berlin just prior to the collapse of the Wall and starring Charlize Theron as Lorraine Broughton, an MI6 operative sent to retrieve a list of agents. Based on the graphic novel The Coldest City, the film was directed by David Leitch, the former stunt performer and co-director of John Wick. The cast includes James McAvoy, Sofia Boutella, John Goodman, and Toby Jones.
The following weapons were used in the film Atomic Blonde:
A Stechkin APS is used by Yuri Bakhtin (Jóhannes Jóhannesson) to kill James Gascoigne (Sam Hargrave), setting the plot into motion. Oddly, characters claim that a Soviet 7.62mm round was recovered from the body, despite the APS being chambered in the 9x18mm Makarov.
Browning Hi-Power
Lorraine Broughton (Charlize Theron) briefly holds a Browning Hi-Power in one scene. Judging from the external extractor and old-style ring hammer, it appears to be a highly desirable 1960s "T" Series Browning Hi-Power.
Makarov PM
The Makarov PM, presumably both East German and Russian models, is used by various characters, including Lorraine (Charlize Theron), KGB agents, and East German Volkspolizei. Several suppressed Makarov pistols are seen in the climax.
SIG-Sauer P226
Lorraine (Charlize Theron) uses a SIG-Sauer P226 several times, most notably to kill "Satchel". West German police officers also use P226s.
A British policeman carries a Heckler & Koch MP5A3 submachine gun with a Navy trigger group. The Navy trigger group is not an anachronism as the first Navy-style trigger groups were made in 1982.
Rifles
MPi-KM-72
East German border guards are seen with AK rifles. It's possible that these are East German MPi-KM-72 rifles.
SVD Dragunov
A KGB agent prepares a suppressed SVD Dragunov with black or black-painted furniture in the attempted assassination of Spyglass (Eddie Marsan).
AS Val
What appears to be an AS Val is used by Lorraine Broughton after taking it from its former KGB user.
