The Single-Six is currently produced as the New Model Single-Six. The term "New Model" simply means that this model includes Ruger's transfer bar mechanism for increased safety, allowing one to carry the revolver safely with all six chambers loaded. Prior to 1973, the Single-Six was produced without the transfer bar mechanism, making it less safe to carry with all six chambers loaded, and with the hammer resting on a loaded chamber. The transfer bar safety allows the revolver to fire only when the trigger has been pulled. Ruger provides the transfer bar safety upgrade free of charge for owners of any old model Single-Six, though this may come with a significant trigger-feel penalty.
The New Model Single-Six is currently chambered in .22 LR, .22 WMR (.22 Magnum), and .17 HMR (initially offered with a second cylinder in .17 HM2). Barrel lengths include 4⅝, 5½, 6½, 7½, and 9½ inches, available in both blued and stainless steel.
Ruger manufactures several "convertible" models that ship with both a .22 LR cylinder and .22 WMR cylinder, allowing the use of both cartridges. The .22 Short and .22 Long cartridges can also be fired in the Long Rifle cylinder. For those models that ship with both cylinders, the last 3 digits of the serial number are engraved on the front of the cylinder; only cylinders that have been properly timed should be used with any given revolver. The term Super Single-Six refers to those models which have fully adjustable target sights.
In 2011 Ruger introduced the Single-Ten and in 2012 they introduced the Single-Nine. Both of these revolvers are stainless steel variants of the Single-Six design with fiber optic sights. The Single-Ten is chambered in .22 Long Rifle, with ten chambers and a 5.5 inch barrel, whereas the Single-Nine is chambered in .22 Winchester Magnum Rimfire (.22 WMR), with nine chambers and a barrel length of 6.5 inches.
.32 centerfire models
From 1984 to 1997 Ruger chambered the New Model Single-Six in .32 H&R Magnum (which allows the use of .32 S&W and .32 S&W Long cartridges). Ruger reintroduced this caliber option in 2002, and in September 2014 released the Single-Seven in .327 Federal Magnum as well, in a seven-shot stainless steel variant, with barrel lengths of 4.62 inches, 5.5 inches, and 7.5 inches.
