Ruger Automatic Pistol (MFG 1978), .22 LR, 4.75 inch Barrel

The Ruger Standard Model (pre-Mark II) manufactured in 1978 is a classic, blowback-operated rimfire semi-automatic pistol. As the foundation of Sturm, Ruger & Co., this iconic handgun features a distinct aesthetic inspired by the sleek profiles of the German Luger and Japanese Nambu pistols. The 4.75-inch tapered barrel configuration represents the original, definitive "plinker" design that popularized the rimfire pistol market. The simple blowback mechanism paired with a completely rigid, non-moving barrel ensures reliable cycling and match-like precision with a wide variety of .22 LR rimfire ammunition.
