Newman's Law is a 1974 American crime film. George Peppard plays an L.A.P.D. detective who runs afoul of gangsters and corrupt officers in his agency who are in league with the mob. It was the first theatrical film directed by television veteran Richard Heffron. Some sources state the script was initially written as a television pilot but was turned into a movie instead. Filmed on a B movie budget and packed with classic Seventies cop movie tropes (not to mention Seventies styles) it is an effective little crime movie with an excellently choreographed gun fight set in a supermarket.
The following weapons were used in the film Newman's Law:
Smith & Wesson Model 15
Vince Newman (George Peppard) carries a Smith & Wesson Model 15 as his sidearm through much of the film. Detective Pete Jimenez (Victor Campos) also carries a Model 15 as does Falcone during the climactic assault on Falcone's house. Filmed in the summer of 1973 the L.A.P.D. provided technical assistance. The agency had switched to the Model 15 in 1970 so the revolver receiving such heavy use is correct.
Smith & Wesson Model 10
Vince Newman (George Peppard) carries a Smith & Wesson Model 10 as his primary sidearm before he is suspended. It is also carried by his commanding officer, Lt. Reardon (Eugene Roche). The L.A.P.D. has historically allowed its officers considerable leeway when it comes to handguns and the Model 10 was one of the models that was authorized as an alternate to the Model 15.
Smith & Wesson Model 28
Winchester 1897 riot-gun
Both uniformed L.A.P.D. officers and members of the hit team sent after Newman use the Winchester Model 1897 during the super-market firefight.
After he is fired from the department Newman (George Peppard) acquires an M16 with the three-pronged flash suppresser. He uses it to take several shots at Falcone and his associates while they are enjoying a beautiful morning next to the pool. Any resemblance to Magnum Force is sheerly coincidental.
