James Bond (Daniel Craig) uses an Anderson Wheeler 500 Nitro Express Double Rifle with box lock in SkyFall. The movie's armourer acquired the rifle from London based gun and rifle maker Anderson Wheeler. The request was for a gentleman’s big game hunting rifle, also known as a 'double rifle'.
More than just a simple novelty in James Bond's arsenal is the ASP, which replaced his famous Walther PPK as his favorite sidearm during the later 1980s novels written by John Gardner and up through the mid 1990s novel
The Walther LP53 is a classic James Bond gun although it never featured in a Bond movie. The gun, with its distinctive long barrel was the weapon of choice for James Bond in many movie posters and promotional photographs.
The subject of Bonds personal firearms has in the past become a heated debate, much akin to the ongoing Omega/Rolex debacle. Everyone has their favourites, be it iconic, practical, real or looks alone.
In the 1987 film The Living Daylights (starring Timothy Dalton) Bond is paired with a fellow MI6 agent to help aid in the extraction of a Russian KGB general. The Walther WA2000 is used to disable a snipers rifle. Bond is given the option between soft-tipped or steel-tipped (armor piercing) rounds, taking the latter as KGB snipers most normally wear body armor.
The Walther PPK was the weapon of choice for James Bond from the films Dr. No to Tomorrow Never Dies (except Moonraker and Octopussy) and again in Quantum of Solace and SkyFall. The gun is also mentioned in the Ian Fleming novels from Dr. No to The Man with the Golden Gun. It's the only gun / gadget that is used by all the Bond actors.
