The Single-Ten holds 10 rounds of .22 LR — the highest cylinder capacity of any single-action .22 revolver in the Ruger lineup. The smaller diameter of the .22 LR cartridge allows 10 rounds in a cylinder sized to the Single-Six frame. The 5.5-inch barrel is the primary configuration. The extra 4 rounds versus a standard 6-shot single-action make the Single-Ten notably more capable for extended plinking sessions.
