Blood Work is a 2002 thriller directed by and starring Clint Eastwood as Terry McCaleb, a retired FBI profiler whose heart transplant is connected to a liquor store murder and a serial killer he had been tracking for years. The film was based on the best-selling novel of the same name by Michael Connelly, the author of The Lincoln Lawyer and the Harry Bosch series.
The following weapons were used in the film Blood Work:
Smith & Wesson Model 627
FBI Profiler Terry McCaleb (Clint Eastwood) carries a Smith & Wesson Model 627 as his sidearm throughout the film. It is a special version featuring an unusual barrel profile and an 8-shot cylinder made by the Smith & Wesson Performance Center. McCaleb's piece has a fluted cylinder, common to other variants of the 627, but not standard on the snub nose version. McCalebs revolver also has Hogue grips.
Heckler & Koch USP Compact
In the surveillance videos of the murders, the killer appears to use a Heckler & Koch USP Compact in 9mm. This type of handgun is also hinted at as the characters call the handgun an "H&K 9mm". In the novel, this weapon was described as a Heckler & Koch P7.
Remington 870 Police Shotgun
When he spots a man observing him from a parked car, Terry McCaleb (Clint Eastwood) takes a Remington 870 Police shotgun with newer style synthetic furniture from the trunk of Detective Jaye Winston's cruiser and uses it to fire at the man as he speeds off. The shotgun is fitted with a 6-shot, side saddle shell holder.
Smith & Wesson 5904
Sheriff's Department Detective Jaye Winston (Tina Lifford) carries what appears to be a Smith & Wesson 5904. She is seen firing it at the suspects vehicle after he nearly runs over Terry McCaleb (Clint Eastwood).
Rocky Mountain Arms Patriot Pistol
At one point in the film, Jasper 'Buddy' Noone (Jeff Daniels) takes a Rocky Mountain Arms Patriot Pistol from a locker on board a ship. The rifle is fitted with an early type carbine stock and a C-More red dot sight. It is clearly not a CQBR as previously mentioned. It has a raised, skeletonized flat-top upper receiver, and lightly ribbed, free-floating front handguard. These are both hallmarks of the Patriot. The barrel also appears to be shorter than the 10.5" of the CQBR, and closer to the 7" barrel of the Patriot.
Smith & Wesson 4506
At the end of the movie, Detective Ronaldo Arrango (Paul Rodriguez) can be seen with what appears to be a Smith & Wesson 4506 in his hip holster. The gun is never seen in full or close up, but the grips appear to wrap around the backstrap, and the 4506 was approved for LAPD carry at the time of filming.
