I have a problem that has perplexed me for the last three years concerning the Ruger Mark IV Target .22 LR pistol I shoot for Steel Challenge competition and just ringing steel for fun. In cleaning this gun over the last three years, I have yet to come out with a clean patch at the end of my cleaning sessions.
Straddling the line between a pistol and a home-defense rifle, Ruger’s newest addition to its 5.7x28 mm line is a great choice for personal protection.
