Ruger 22/45 is a semi-automatic pistol manufactured by Sturm, Ruger & Co. since 1992. The 22/45 combines elements of the Ruger Mark II, Colt 1911, and the Nambu Type 14 into a pistol intended for use in competition shooting.
The 22/45 is a two-part design, in which the grip frame and trigger are manufactured from a Zytel ® polymer, while the receiver and barrel are manufactured from aluminium. The aluminium is aircraft grade for both strength and lightness, meaning that the 22/45 weighs as little as 1.4lbs (0.65kg), making it one of the lightest pistols on the market today.
The 22/45 uses a blowback action, similar to the Nambu pistol of Imperial Japan in the Second World War. This means that the potential for misalignment of the sights through the movement of a slide (which most .22 LR pistols use) is avoided. The barrel has six rifling grooves with a 1:16 inch ratio twist, and is threaded to accept a silencer or other barrel accessories.
Numerous safety mechanisms are also fitted to the 22/45. As well as a conventional manual safety to lock the sear, the 22/45 is fitted with a loaded chamber indicator and a magazine disconnect, intended to prevent accidental fire if the magazine has been removed, but a round still remains in the chamber. The ejection port has also been designed with user safety in mind, angled and contoured to prevent ejected casings from hitting the user.
The Ruger 22/45, as the name suggests, is a .22 caliber pistol, chambered to accept the .22 Long Rifle cartridge. These are fired from a ten-round magazine, which slots into the grip. A magazine release button can be found on the left side of the frame, above the trigger guard.
