Ruger Mark IV 22/45 Lite Diamond-Gray .22 LR Threaded Barrel Semi-Auto Pistol
This Mk IV 22/45 Lite pairs Ruger’s one-button takedown system with a lightweight 25-ounce build and a distributor-exclusive diamond-gray anodized receiver. A tensioned, cold-hammer-forged 4.40-inch stainless barrel sits inside a ventilated aluminum shroud and ends in a 1/2-28 TPI thread, ready for rimfire suppressors or compensators. The full-length Picatinny rail, gold-tone skeletonized trigger, and 1911-style 22/45 grip frame give this pistol a distinctive mix of function and style.

The 22/45 Lite’s polymer grip frame matches the 1911 grip angle and accepts replaceable checkered black panels with Ruger phoenix medallions, giving shooters familiar ergonomics in an ultralight package.
A full-length integral Picatinny rail is machined into the receiver, providing a solid base for optics while retaining black iron sights—an adjustable rear paired with a fixed front blade in a dovetail.
The pistol uses a single-action blowback system with an internal hammer. An ambidextrous manual thumb safety, magazine disconnect, and sear-block safety deliver multiple layers of security without complicating the manual of arms.
Ruger’s gold-anodized skeletonized trigger offers a crisp break, complementing the flagship one-button takedown that separates the upper and grip frame for fast cleaning and maintenance.
Built in 2022 in the USA, this Mark IV 22/45 Lite (part number 43934) combines modern materials, a threaded barrel, and an eye-catching finish—ready for target work, small-game duty, or suppressed rimfire fun.
