Detailed Features 

 
The Single-Six Convertible ships with two cylinders -- .22 LR and .22 WMR -- allowing you to switch calibers based on what you're doing. The alloy steel frame with blued finish is durable and keeps weight manageable at 2.1 lbs. The adjustable rear sight and ramp front sight let shooters tune for different distances and ammunition. The standard single-action trigger gives a clean, consistent pull. Checkered rubber grips provide traction in wet or cold conditions and hold up over extended sessions. The transfer bar safety is the primary passive safety mechanism, preventing discharge unless the trigger is fully pressed. 
 

Usage Scenarios 

1. At the range, the .22 LR cylinder is cost-effective for extended target practice. 
2. The .22 WMR cylinder adds velocity for small game like rabbits and squirrels. 
3. The light recoil and single-action operation make it an accessible firearm for introducing new shooters to revolver basics.

The Ruger Single-Six Convertible .22 Revolver with a 5.5-inch barrel is well-regarded by firearm enthusiasts, with most feedback centering on its versatility and reliability.

The dual-caliber feature is consistently praised. Running both .22 LR and .22 WMR from one gun suits a wide range of activities -- target practice, plinking, and small game hunting -- without needing separate firearms. The lightweight build and controllable recoil make it accessible to newer shooters while still satisfying experienced ones.

Build quality gets strong marks. Ruger's manufacturing reputation holds up in practice, with owners describing the Single-Six as solid and well-fitted. The smooth action and clean trigger pull are frequently highlighted as contributing to an enjoyable shooting experience.

Some discussions compare the single-action format unfavorably to modern semi-autos in terms of firing speed. Many owners see this as a feature rather than a limitation -- the deliberate cock-and-fire process encourages aimed, measured shooting. That said, it's a real consideration for anyone who prioritizes rapid follow-up shots.

The classic design appeals to traditionalists, and the 5.5-inch barrel length is popular for its balance between portability and sight radius. Overall sentiment is positive, with most owners satisfied with the revolver's performance across plinking, hunting, and training uses.
