A Better Tomorrow is a 1986 Hong Kong action film directed by John Woo and starring Chow Yun-Fat as a friend to a pair of brothers who decide to take on the Triad crime organization. The film would spawn the 1987 sequel A Better Tomorrow II and the 1989 prequel A Better Tomorrow III.
The following firearms were used in the film A Better Tomorrow:
The Smith & Wesson Model 10 revolver is carried by Kit (Leslie Cheung) as his police service weapon. A suppressed version is also used by an assassin who attempts to kill Ho and Kit's father.
Smith and Wesson Model 28 Highway Patrolman
One of the Taiwanese gangsters who attempts to fire at Mark (Chow Yun-Fat) during the shootout at the restaurant uses a Smith & Wesson Model 28 revolver.
Beretta 92F
John Woo's favorite handgun, the Beretta 92F makes frequent appearances in this film. All three main characters use the pistol at different times in the movie, as do many of the Triads.

Beretta 92SB
The Beretta 92SB is seen in the hands of Shing (Waise Lee) and a few Triads throughout the film, and is identifiable by its rounded trigger guard, and modern Beretta grips (versus the older style grips of the Original 92).
Smith & Wesson 39
Ho (Ti Lung) carries a Smith & Wesson 39 pistol during the scenes set in Taiwan, and the gangster that betrays him also uses one during the restaurant shootout. Other Triad members use the pistols during the shootout in the garage and at the docks.
Colt M1911A1
Many M1911 variants show up in this film, seldom clearly enough to make an ID. Seen mostly in the hands of Triads.
Browning Hi-Power
The Browning Hi-Power is relatively common in early Woo films. When Mark is engaged in a shootout at the restaurant, one of his Beretta's turns into a Browning. Mark is seen later dual-wielding the Browning alongside his Beretta while retrieving a data tape.
