This specific configuration of the Ruger Mark IV pistol denotes a variant designed for accuracy and adaptability. It combines the reliable Mark IV platform with a longer, heavier barrel profile intended to enhance precision. The key feature is the threaded muzzle, enabling the attachment of suppressors or other muzzle devices.
A longer, heavier barrel offers several advantages for target shooting. Increased sight radius improves aiming precision, while the added weight reduces muzzle flip and felt recoil, leading to faster follow-up shots and improved overall accuracy. The threaded muzzle allows for the use of suppressors, mitigating noise and muzzle blast, which can enhance concentration and reduce shooter fatigue. This combination of features makes it a popular choice for competitive shooting, plinking, and small game hunting where accuracy and a quieter report are desired. This build upon the legacy of the Mark series pistols, known for their reliability and accuracy.
