The Ruger Single-Ten is a full-size .22 LR single-action revolver with a 10-round cylinder, 5.5-inch barrel, and Williams Adjustable Fiber Optic sights. The satin stainless steel frame and barrel give it both corrosion resistance and a clean look. Hardwood gunfighter grips fill the hand well and look good against the stainless finish.

Detailed Features 

 
The Williams Adjustable Fiber Optic sights are a practical upgrade over the fixed irons common on revolvers in this class. They adjust for both windage and elevation, and the fiber optic inserts pick up light well in variable outdoor conditions. 
 
The transfer bar safety system allows carrying all 10 chambers loaded safely. Unlike older single-action designs that require leaving the chamber under the hammer empty, the transfer bar prevents firing unless the trigger is intentionally pulled. At 38 oz the Single-Ten has enough weight to tame .22 LR recoil to almost nothing, which makes long range sessions genuinely comfortable. 
 
Single-action operation requires manually cocking the hammer before each shot. This slows the rate of fire compared to double-action revolvers but makes each shot more deliberate, which most owners find useful for building trigger discipline.

The Single-Ten is well-regarded among .22 revolver owners. The 10-round capacity gets frequent praise as a meaningful improvement over 6-shot .22 revolvers without changing the gun's handling. Accuracy is a common topic; many owners report tight groups at 25 yards, which makes it popular for both target practice and teaching new shooters.

.22 LR is cheap to shoot, and the Single-Ten's single-action mechanism makes every round deliberate. Experienced shooters use it to work on technique without the expense of larger calibers. New shooters get manageable recoil and a gun that forces good habits.

Some criticism focuses on the weight and overall size. At 38 oz and 11 inches overall it isn't compact, which matters for some users. The single-action learning curve relative to double-action revolvers also comes up. Most owners consider this a feature rather than a drawback but it's worth knowing before buying. The finish and overall fit are consistently praised.
