The Ruger Mark IV 22/45 model 40192 pairs the 1911-angle grip frame with a longer 5.50" bull barrel for an extended sight radius and improved balance for deliberate target work. The threaded muzzle at 1/2x28 accommodates suppressors and muzzle devices, while the distinctive engraved walnut grip panels add a premium aesthetic to this collector-grade variant of the classic Mark series. Internal cylindrical bolt construction ensures permanent sight-to-barrel alignment that conventional slide-action designs cannot match. One-button takedown simplifies cleaning, and the receiver is drilled and tapped for scope or red dot mounting.
