Sturm, Ruger & Company, Inc.'s 22/45 rimfire pistol models with threaded barrels 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 (available at ShopRuger.com) 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.
