The Ruger Mark IV Tactical pistol in .22 LR with a 4.4-inch threaded barrel (brand part no. 40150) brings top and bottom Picatinny rails to Ruger’s proven rimfire platform, giving shooters a training and suppressor-ready package built for tactical accessories. Ruger finishes the pistol in black oxide over an alloy steel slide and aluminum grip frame, and a one-button takedown allows quick field-stripping without tools. The internal cylindrical bolt construction ensures permanent sight-to-barrel alignment for higher accuracy than conventional slide designs, and the adjustable rear sight pairs with a fixed front. The pistol runs an ambidextrous safety, feeds from two 10-round magazines, and weighs 34.6 ounces. Among rimfire semi-auto handguns, this Mark IV Tactical configuration favors shooters who want threaded, rail-equipped training pistols.
