Lewis is a British detective drama TV series, a spin-off of Inspector Morse series. Robert "Robbie" Lewis (Kevin Whately), Morse's sergeant in the original series, is promoted to DI and continued his work in the Thames Valley Police. In the latest series, Lewis had retired from the police, but is brought back as a consultant. Stories are mostly set in Oxford, often connected with the University of Oxford.
In "Reputation" (Pilot episode) Danny Griffon (Charlie Cox) owns a Smith & Wesson Model 10HB revolver that is used as a murder weapon several times throughout the episode. Dr. Laura Hobson correctly identifies it a .38 gun.
In the opening scene in "Old School Ties" (S01E02) an Oxford student Jo Gilchrist (Frances Albery) gets a Smith & Wesson Model 60 revolver as a birthday present. David Harvey (James Russell) who gifted the revolver claims that it was his grandfather's wartime gun (which is obviously wrong for Model 60).
In the climactic scene in "The Dead of Winter" (S04E01) Paul Hopkiss (Pip Carter), the butler in Mortmaigne's estate, raises an Enfield No. 2 Mk I revolver at DI Lewis. (Really, "The butler did it"!)
In "Reputation" (Pilot episode) Rex Griffon (Jack Ellis), Mr. Tanigaki (Dennis Matsuki) and several other Griffon Cars executives and their Japanese visitors use Over and Under Shotguns for skeet shooting.
Richie Maguire (David Hayman) fires a Double Barreled Shotgun in several scenes in "Counter Culture Blues" (S03E04). A double barreled shotgun is seen next to the dead body of Ralph Grahame (Jonty Stephens) in "The Dead of Winter" (S04E01); two more shotguns are seen in Grahame's house.
In the opening scene in "The Dead of Winter" (S04E01) a group of English Civil War reenactors widely use Matchlock Muskets. During the event one of the muskets fires a live bullet which is hardly possible for a weapon, used by reenactors.
Several bolt action rifles, some with sniper scopes, are seen on shooting range in "Dark Matter" (S04E02). They are used by Isobel Crompton (Sophie Ward) and Kate Cameron (Ruby Thomas). In the climactic scene Babs Temple (Annabelle Apsion) holds a rifle. Police expert claims the rifles to be of .22 caliber.
