In Episode 1, Lee Jin-Pyo (Kim Sang-Jung) and Park Mu-Yeol (Park Sang-Min) are armed with the Beretta 92FS Brigadier during their time as Presidential Security Service bodyguards in Myanmar after an assassination attempt in 1983. Its presence in the 1980s is an anachronism as it was not made until the early 1990s. In Episode 3, Lee Yun-Seong (Lee Min-Ho) is armed with the 92FS Brigadier when he confronts the corrupt politician Lee Kyung Wan. However, this pistol does not fire live bullets as Lee had modified the sidearm offscreen to fire tranquilizer darts. Used by a PSS agent in Episode 7 before Min-Ho disarms him. Jin-Pyo uses this in Episode 5 after his assassination attempt had failed.
In Episode 1, Jin-Pyo uses the Beretta 92FS Inox as his main sidearm after conducting his self-exile from South Korea to Thailand over the failure of the black ops mission to North Korea.
Used by a young Yun-Seong during target practice in Thailand. Also used by an adult Yun-Seong to save his surrogate mother from being executed by shooting fruits dangling near her.
Jin-Pyo uses this in Episode 4 under his police officer disguise after he covertly took the Model 36 from a holster of a police officer driving the bus.
Jin-Pyo uses one with black grips and a three inch barrel to intimidate Seo Yong-Hak after capturing him. He also uses it to intimidate Yun-Seong and Na Na before he left the underground parking lot.
Gunmen working for Jin-Pyo in Thailand are armed with the H&K MP5A3. South Korean SWAT officers after responding to the Seoul Intercontinental Hotel shooting attempt are armed with H&K MP5A3. Also used by KNP SWAT teams to hunt down Seo Yong-Hak.
Used by some narcogunmen after firing at Yun-Seong's room. Used by Jin-Pyo and Mu-Yeol as part of their Korean People's Army disguise after infiltrating North Korea by sea.
Only used by a narcogunman before he was shot in the back of the head by Jin-Pyo.

Guns just like this one have been used in Tropic Thunder, Three Kings, and numerous other movies and TV shows.Error creating thumbnail: File missingThe gunman shot at the back has an AKMSU. You can only see it for a split second.
M16A1
Used by Jin-Pyo's henchmen in the 1st episode. Most likely Vietnam War-based surplus. Also used by narcogunmen working under a local drug smuggler.
Myanmar soldiers in honor guard duty are armed with the M16 in the 1st episode. This may be an error as the Myanmar Army were not armed with the M16 and instead, had G3 rifles as their main rifle. In the same episode, an Underwater Demolitions Unit (An ROK Navy black ops unit) commando snipes the black ops soldiers under orders from an ROK submarine. Jin-Pyo uses one to try and assassinate an ex-ROK officer turned politician.
