Ruger Mark IV 22/45 Lite 22 Long Rifle Pistol 4.4" Non-Threaded Barrel 10+1 Round Black Slide Black/Gray Grip Black Frame

From MidwayUSA

Ruger redesigned the platform of their famous 22 pistol to make the Mark IV 22/45 LITE Semi-Auto Rimfire Pistol with a simple rear-mounted takedown button and a frame-mounted pivot pin that eliminate the complexities of field stripping previous models. The Mark IV pistol disassembles and reassembles easily, allowing proper chamber to muzzle cleaning. The 22/45 LITE utilizes a single-piece, aerospace-grade aluminum receiver with a ventilated barrel shroud that houses a tensioned stainless steel barrel. The aluminum receiver coupled with a Zytel polymer grip frame results in a super lightweight, full-sized pistol.
