The Ruger Mark IV Standard pistol in .22 LR with a 4.75-inch blued barrel (brand part no. 40104) continues Ruger’s decades-long rimfire pistol lineage, built for target shooters and plinkers who want an accurate, reliable .22. Ruger gives the Mark IV a satin stainless barrel finish under blued steel, a black polymer grip, and fixed sights, and the frame is drilled and tapped for optic mounting. Two 10-round magazines ship with the pistol, and an ambidextrous manual safety supports both right- and left-handed shooters. Among rimfire semi-auto handguns, this Mark IV Standard configuration favors target practice and training.
