The Ruger Mark IV 22/45 Lite 4.4" .22 LR Pistol (Ruger part no. 43916) pairs Ruger’s legendary Mark IV rimfire action with a lightweight anodized aluminum bull barrel and a 1911-angled polymer grip frame, giving shooters the familiar Mark-series accuracy in a lighter, more ergonomic package. The Mark IV’s headline feature — true one-button takedown with no tools required — makes cleaning dramatically simpler than earlier Ruger .22 pistols, a welcome upgrade for range regulars and new shooters alike.
