Breaking News (original Chinese Title: 大事件; Cantonese: Daai si gin) is a 2004 film directed by Johnnie To about an attempt by Hong Kong Police to use the media to rebuild their reputation after an embarrassing defeat in a shootout is broadcast all over the news, however, their 'operation' goes horribly wrong.
The Taurus PT92 is used by all of the members of Yuan's (Richie Ren) gang, as well as by assassin Chun (You Yong) and his partner. Inspector Cheung (Nick Cheung) later takes a PT92 from one of Yuan's men and uses it when the criminals attempt to escape the apartment building they are hiding in.
Colt Detective Special
The Colt Detective Special is the standard sidearm for all officers of the Criminal Investigative Branch (CIB) in the Hong Kong Police Force, including Inspector Cheung and his partner Hoi (Shiu Hung Hui). Superintendent Rebecca Fong (Kelly Chen) also uses a Detective Special when following Yuan after he escapes from the police cordon.
The last picture is definitely a Smith and Wesson Model 36. The ejector rod is closer to the barrel than the Colt.-saints

Uniformed officers of the Hong Kong Police Force, including officers of the Police Tactical Unit (PTU) are armed with Smith & Wesson Model 10 revolvers.
