READY GUNNER PURCHASE GUIDE
Ruger Mark IV 22/45 Lite .22 LR Pistol – 4.4 in. Threaded
The Ruger Mark IV 22/45 Lite is a semi-automatic .22 LR pistol with a 4.4-inch threaded barrel and a lightweight ventilated aluminum receiver — 25 ounces total. It pairs the Mark IV's one-button takedown with the 22/45's 1911-style grip angle, and ships with two 10-round magazines in a lockable hard case.
Tensioned Threaded Barrel
The 4.40-inch barrel is tensioned stainless steel, cold hammer-forged, with a 1:16-inch right-hand twist and six grooves. The muzzle is threaded 1/2x28 and a thread protector is included.
One-Button Takedown
A recessed button in the back of the frame lets the upper receiver tilt up and off the grip frame without tools, for chamber-to-muzzle cleaning. The internal cylindrical bolt keeps the sights permanently aligned with the barrel.
Lightweight Ventilated Receiver
The receiver is aerospace-grade aluminum with ventilation cuts, black anodized. The grip frame is glass-filled nylon with a 1911-style grip angle, checkered replaceable grip panels, a serrated front strap, and a checkered backstrap.
Sights and Rail
A fixed front blade and a fully adjustable rear sight are fitted, and a Picatinny rail comes factory-installed on the drilled-and-tapped receiver — the iron sights remain usable with the rail mounted.
Controls and Safeties
Controls include ambidextrous thumb safeties (convertible to left-side only with the included washer), a left-side push-button magazine release with drop-free magazines, and a magazine disconnect safety.
