Notes: The Model 31 is based on an earlier revolver, the Model 30 Hand Ejector (which was in turn based on the earlier M-1903 Hand Ejector), and was built on the new (at the time) I-Frame starting in 1949, and continuing until 1960. Finish was blued or nickel-plated, and the revolver had a rounded butt with walnut grips. The Model 31-1 was a version of this revolver based on the J-Frame instead of the old (by then) I-Frame; it was built from 1960-76. The Model 31 Regulation Police Target was a rare variant of the Model 31 (only 200 built); it had an adjustable target-style rear sight, but is otherwise identical to the standard Model 31 for game purposes.

Notes: This is a 6-shot revolver with two different barrel lengths. The Model 34 could be blued or nickel-plated, and is built on the small J-Frame, and is essentially a .22 weapon built on a .32 frame. It has a micrometer rear sight and a walnut grip. The Model 34 was introduced in 1953 and remained in production until 1991.

The Model 35 is a basically a Model 34 with a longer (6-inch) barrel, designed for shooting matches. It was introduced in 1953 and production stopped in 1973.

Notes: This weapon was first shown to the public at a police officer’s conference in Colorado in 1950; the officers themselves gave the weapon the name "Chiefs’ Special." It was the first of their small J-Frame revolvers. The Model 36 became popular with undercover police officers and higher-ranking officers due to its small size.

Notes: This is a lighter version of the Model 36, and at the time of its introduction (1952) was also known as the Aircrewman, a nod to hoped-for sales to the Air Force. It was originally built with a blued alloy cylinder and alloy frame, but it was discovered that the alloy cylinder of the time could not hold up to prolonged use of the .38 Special round, and it was replaced by a steel cylinder in 1954. It was also originally available with a 2- or 3-inch barrel, but the 3-inch barrel was dropped in 1988. The walnut grips were replaced with rubber grips in 1994. In 2000, the barrel was shortened by another 3 millimeters. Production of the Model 37 stopped entirely in 2001, but a stainless steel-cylinder version remained in production as the Model 637 Chiefs’ Special, capable of firing +P rounds.

Twilight 2000 Notes: The 2000 version of the Model 37 is not available, nor is the Model 637.

Smith & Wesson 38 Bodyguard

Notes: This is an aluminum-frame revolver that features a fully shrouded hammer. The Model 38 was specifically designed to be carried concealed (the covered hammer does not catch on clothing and makes for a faster, smoother draw). The short barrel and light frame make accuracy difficult.

The Model 638-3 is an updated version of the Model 38 Bodyguard; it has a faux stainless steel finish (called "bead-blasted" by Smith & Wesson) over its aluminum-alloy frame. The grips are of soft rubber, cushioning the hand as well as providing a positive grip. The ejector rod is unshrouded, which can lead to problems with bending, with attendant problems with rotation of the cylinder. The front sight is a ramp-type, but the rear sight is a simple shallow trough in the top strap – making it difficult to use in quick-aim situations. The Model 638-3 has a safety catch as well as a hammer lock which is operated by inserting a key.

Notes: This is a lightweight rimfire revolver with a 2.25" or 3.5" barrel. It is available in blued or nickel-plated versions, and has a micrometer rear sight. The frame is of light alloy, with a steel cylinder. Most were made to fire .22 Long Rifle, but a few were built for .22 Winchester Magnum Rimfire ammunition. It was produced from 1954-1974.

Notes: Introduced in 1959, this K-frame revolver was designed to fire the .22 Winchester Magnum Rimfire cartridge, with an option for an interchangeable cylinder to fire .22 Long Rifle. It was available only in a blued version, with three barrel lengths. The Model 48 has a micrometer adjustable rear sight, counterbored cylinders, and a walnut grip. Production stopped in 1986.

Notes: This is a J-Frame revolver introduced in 1960, and built until 1974. It has a micrometer adjustable rear sight, sunken cylinder chambers, and a 3.5-inch barrel. An option was an interchangeable cylinder to enable the Model 51 to fire .22 Long Rifle ammunition. The Model 51 could be blued or nickel-plated, with walnut grips.

Notes: This is an updated Model 36 Chief’s Special, known as the Model 60 Chiefs’ Special Stainless, and made from stainless steel to resist corrosion from sweat and body oils when carried in an inside-the-pants or shoulder holster. It was originally built only with a 2.25-inch barrel, but a 3-inch barrel version was added in 1972. The Model 60 had walnut grips until 1994, when a change to soft rubber was made. In 1994, the barrel length of the short version was made 3mm longer. In 1994, the revolver was strengthened and the caliber changed to .357 Magnum (and .38 Special). This revolver is still being manufactured today. About the same time, the Model 60-18 was introduced; this version has a stainless steel frame, barrel and cylinder, a full 5-inch barrel, a front sight with a orange plastic insert and an adjustable rear sight, rosewood grips designed specifically for smaller hands, a shrouded ejector rod, and a contoured trigger. Smith & Wesson describes it as a "target revolver for the shooter with smaller hands."

A variant of the Model 60 is the Model 60LS Ladysmith Stainless. As the name would indicate, it is a version designed for ladies’ self-defense and made with a stainless steel frame and cylinder. They have a 2- or 3-inch barrel. They were introduced in 1989; until 1992, they had wooden grips, but afterwards, they were given soft rubber grips. In 1996, the caliber was changed from .38 special only to .357 Magnum and .38 Special. The Ladysmith Stainless is still available, but now has a 2.17" barrel only. The Ladysmith Stainless is somewhat lighter than the Chiefs’ Special Stainless.

Another variant, introduced in 2005, is the Model 60 Trail Gun. It has a full 5-inch barrel, adjustable rear target-type sights, oversized rosewood grips with finger grooves, and with precision fit and finish (which is of stainless steel with a satin finish). It is designed for defense against wild animals, hence its name, and since it is meant for long-distance carry, is surprisingly light in weight.

Twilight 2000 Notes: .357 Magnum versions of the Model 60LS Ladysmith Stainless are not available in the Twilight 2000 timeline, nor is the Model 60 Trail Gun.
