Blood Work is a 2002 thriller starring Clint Eastwood as a retired FBI profiler whose heart transplant is connected to a liquor store murder and a serial killer he had been tracking for years. Based on the best-selling novel by Michael Connelly.
The following weapons were used in the film Blood Work:
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.
Heckler & Koch USP
In the surveillance videos of the murders, the killer appears to use a Heckler & Koch USP 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 Shotgun
When he spots a man observing him from a parked car, Terry McCaleb (Clint Eastwood) takes out a Remington 870 with synthetic furniture and fitted with a saddle shell holder to shoot at him as he speeds off.
At the end of the film, Jasper 'Buddy' Noone (Jeff Daniels) uses what appears to be a Rocky Mountain Arms Patriot Pistol with a first type carbine stock and a C-More red dot sight. It is clearly not a CQB-R as previously mentioned. It has a raised, skeletonized flat-top upper reciever, 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 539
At the end of the movie, Detective Ronaldo Arrango (Paul Rodriguez) can be seen with what appears to be a Smith & Wesson 539 with black grips in his hip holster.
