The Mark IV 22/45 Lite uses a one-button takedown system — pressing a button at the back of the frame allows the barrel-receiver assembly to tilt up and off the grip frame without tools. The internal cylindrical bolt construction maintains permanent sight-to-barrel alignment. An ambidextrous manual safety can be converted to left-side only with the included washer, and the push-button magazine release on the left side of the frame allows the magazine to drop free on release. A magazine disconnect prevents discharge when the magazine is removed.

The cold hammer-forged barrel features 6 grooves with a 1:16 RH twist rate. The threaded barrel is compatible with the Ruger Silent-SR sound suppressor. Note: color and shade of anodized components may vary from photos.
