The Smith and Wesson’s Model 617 is built on the company’s famous K-frame with an external hammer, which serves the American people since 1899. It is a full-sized, stainless-steel, rimfire revolver chambered in affordable .22 LR ammo, with an amazing capacity of 10 bullets. The Model 617 is available in two barrel lengths, 4 and 6 inches. Both versions are greatly accurate, and the 4-inch variant feels slightly better balanced in a hand. It’s a pretty heavy revolver, but its weight contributes to accuracy and balance. The revolver features a single and double action trigger, smooth and flawless. The steel has a satin finish that gives the gun lifetime durability, and the hammer has checkering, for a firm grip. An automatic safety prevents contact between the firing pin and the hammer until the trigger is fully pulled. There is also a manual safety located on the left side plate, above the cylinder release control. The typical S&W sights include a pinned Patridge-type front sight, and rear sight, both replaceable. This gun is convenient for training new shooters because of almost non-existing recoil, and it has been one of the favorite choices among experts and professionals as well. The 10-round cylinder also makes it perfect for competition and shooting sports.
