The President's Last Bang (2005).

The President's Last Bang (Korean title: 破그때 그사람들, Geudttae Geusaramdeul; lit. "The People of Those Days") is a 2005 Korean satirical black comedy film based on the 1979 assassination of South Korean president Park Chung Hee by his close friend and then-Korean Central Intelligence Agency Director Kim Jae-kyu.

The following weapons were used in the film The President's Last Bang:

Pistols

M1911A1

What appears to be a M1911A1 is seen with a Korean Central Intelligence Agency (KCIA) agent during a standoff with the Presidential Security Service (PSS).

Walther PPK

True to life, a Walther PPK is used by KCIA Director Kim Jae-kyu (Baek Yun-shik) when he first tries to kill President Park Chung-hee. As in reality, the pistol jams at one point before the president was fatally shot.

Walther PPK - .32 ACP

Director Kim brandishes his PPK, starting the events that led to President Park's death.

Director Kim clears the jammed pistol. Note that the real Kim Jae-kyu's PPK actually did jam during the assassination.

Revolvers

Ruger GP100

The Ruger GP100 is seen with KCIA Agent Ju (Suk-kyu Han) and Director Kim. This is incorrect since the revolver did not see production until the mid-1980s.

Well, he did it...

Smith & Wesson Model 36

The Smith & Wesson Model 36 is used by KCIA agents, including Agent Min (Eung-soo Kim), recruited by Agent Ju to assassinate President Park and his PSS detail. This revolver was actually used by the KCIA when the president was assassinated.

Submachine Guns

Heckler & Koch MP5A3

The Heckler & Koch MP5A3 is used by the KCIA as one of their primary weapons next to the M16A1.

Assault Rifles

M16A1

The M16A1 is seen with and with no bayonet by the South Korean Army and the KCIA. These are likely Daewoo-made since Seoul was allowed to make them under license by Colt.
