The Ruger Mark IV Target pistol in .22 LR with a blued threaded bull barrel and blued aluminum frame (brand part no. 40178) is a Target Sports South exclusive that pairs the proven Mark IV platform with a suppressor-ready barrel. Ruger cold-hammer-forges the 5.5-inch barrel and machines an internal cylindrical bolt for permanent sight-to-barrel alignment, and a one-button takedown makes field-stripping and chamber-to-muzzle cleaning fast. The drilled and tapped receiver accepts a Weaver or Picatinny rail, and the ambidextrous manual safety can be converted to left-side only with the included washer. Two 10-round magazines ship with the pistol. Among suppressor-ready semi-auto handguns, this Mark IV Target configuration favors shooters who want a threaded .22 LR platform.
