K-9 is a 1989 action comedy starring James Belushi as Michael Dooley, a San Diego police detective who reluctantly partners up with a drug sniffing canine named "Jerry Lee" in order to take down a drug lord who has targeted him for elimination. The film was released only three months prior to the similarly-plotted Tom Hanks action comedy Turner & Hooch. The success of K-9 would spawn two DTV sequels: K-911 (1999) and K-9: P.I. (2002).
The following weapons were used in the film K-9:
San Diego Police Department Detective Michael Dooley (James Belushi) carries a Beretta 92SB with wood grips as his primary weapon in this movie. The handgun is most prominently seen when Dooley lays his gun on the hospital tray table. In one scene, he mentions to "Jerry Lee", his new German Shepherd partner, that he's going to pull out his "revolver". (How do you mistake a Beretta 9mm for a revolver?!)
A Beretta 92FS is briefly seen drawn by San Diego Police during the standoff.
Smith & Wesson Model 39
Lyman (Kevin Tighe) uses a Smith & Wesson 39 in polished nickel. He uses it first to hold Dooley's wife, Tracie (Mel Harris) at gunpoint, and again to shoot Jerry Lee (the dog in the film). When Dooley says the line "You think this is a Nine Millimeter mistake?", he wasn't kidding.
