The Lite variant uses a ventilated, lightened aluminum upper with elongated oval windows and a gray anodized finish. This construction keeps weight down while maintaining the 22/45 grip angle and feel. The grip frame accepts checkered, replaceable 1911-style panels with a molded Ruger logo.
The stainless steel barrel is tensioned and threaded 1/2-28 TPI, with a thread protector installed. A visible barrel sleeve and the 4.40 in. length balance handiness with velocity in a compact package.
Factory sights include a fixed front blade and a fully adjustable rear target sight. A receiver-mounted Picatinny rail section is installed at the factory for straightforward mounting on the upper receiver; it runs between the sights and does not extend the full length of the upper.
Controls include a left-side magazine release and a left-side manual thumb safety. The trigger is gold-colored, and the action is a simple, reliable blowback design with a 10+1 capacity.
Ruger’s Mark IV one-button takedown simplifies maintenance. Markings include “RUGER MARK IV 22LR PRESCOTT AZ USA” and “LITE.” This example corresponds to Ruger part number 43934 and weighs approximately 25 oz.
