Ruger has been listening to the suggestions from Steel Challenge shooters, as well as other aficionados regarding its 22/45 and is producing the pistol with factory installed rails and a threaded barrel. The 22/45 comes with a 10-slot rail on top and a 6-slot rail under the barrel to allow for easy installation of a holographic sight on top and a laser, flashlight, or other accessory on the under-barrel mount. The barrel is also factory threaded 1/2×28 to accept a suppressor or other .22 caliber muzzle device and includes a thread protector.
From their press release: Ruger announced two new 22/45 rimfire pistol models with threaded barrels. These new models allow owners to attach an assortment of muzzle accessories to one of America’s favorite rimfire handguns, the popular Ruger 22/45RP rimfire pistol.
Both models feature a 4.5 inch, factory ½-28 thread barrel, which accepts many popular muzzle accessories. When not using a special application attachment, the threaded barrel and barrel crown are protected by a muzzle cap.
The 22/45PRRP model (10149) comes without sights and features a Picatinny rail on top of the receiver for mounting optics. A shorter Picatinny rail is mounted on the bottom of the barrel for attaching lights, lasers and other accessories.
The second model (10150) features a fixed rear sight and Partridge-style front sight. The receiver is drilled and tapped to accept a Weaver-style scope adapter so shooters can mount a variety of optics on the pistol.
Like all pistols in the 22/45RP lineup, the new Ruger 22/45 Threaded Barrel pistols have replaceable 1911-style grip panels on the polymer frame that features the grip angle of the classic 1911. Similarly, the locations of the magazine button, manual safety, and bolt stop are virtually identical to the classic 1911 pistol. The slim polymer-grip frame has a serrated front strap and a checkered back strap.” Click here to purchase a Ruger 22/45 with Picatinny rail and threaded barrel.
