[Tanaka] S&W M66 6inch Stainless Finish Ver.3 Gas Gun (New release on May 12, 2026 - Pre-order)

S&W M66 6inch Stainless Finish Ver.3 

The K-frame series of real firearms is one of the most important models in Smith & Wesson's history, and the M19, in particular, was introduced as a model that combined portability with the ability to fire powerful .357 Magnum rounds. Nicknamed the "Combat Magnum," it was widely adopted by law enforcement agencies in the United States and is a popular model that frequently appears in movies, TV dramas, manga, and animated works. The M66 is the stainless steel version of the M19. The "6" at the beginning of M66 denotes stainless steel as the material. (Although the naming rules are quite irregular now.) Due to its stainless steel properties, it is resistant to rust and corrosion, making it a highly sought-after model for law enforcement officers who carry it for long periods, plainclothes detectives who carry it in shoulder holsters, and for home defense, as it requires less meticulous maintenance than iron.
The 6-inch barrel was difficult to carry and was adopted by only a few police departments, but the accuracy derived from the long barrel was considered a significant advantage as a stock gun in matches such as PPC (PPC stands for Police Practical Combat or Practical Pistol Course, a police shooting training course that was popular nationwide) and other competitions.
 
Now, the 6-inch M66 is available as a Ver.3 gas gun. In addition to changes in markings and a review of the exterior shape, weights have been added inside the grip, improving not only the weight but also the balance when held. Furthermore, the K-frame wide hammer and wide trigger, which were mounted on the 6-inch M19, have a plated finish, and the improved texture of the stainless steel plating gives it a luxurious appearance. Internally, it also pursues the ultra-smooth operation characteristic of SW, and the definitive edition of the M66 gas gun is now available as the Version 3 model.
