The Mark III Target configuration pairs a fixed barrel/receiver with an internal reciprocating bolt and a simple blowback, single-action system. This layout is characteristic of the Ruger Mark series and contributes to consistent operation with .22 LR.
The 5.5 inch bull barrel provides a steady sighting platform. Sighting is handled by a ramped front sight with an orange insert and an adjustable target rear sight, allowing the shooter to dial in elevation and windage as needed.
Controls are set up for practical use, with a magazine release located behind the trigger guard, a manual safety, and a loaded chamber indicator. Rear grasping ears on the bolt facilitate easy charging.
Construction is all blued alloy steel for the barrel, receiver, and frame, complemented by smooth hardwood grip panels. Factory-listed overall length is approximately 9.75 inches with a weight of about 42 ounces, and this example was manufactured in the USA in 2010. It is cataloged as MKIII512 with manufacturer part number 10101.
Capacity is 10+1 rounds of .22 LR. This pistol comes with three 10-round magazines, a Ruger factory gray hard case with matching end label, and the original instruction manual.
