Ruger GP100 .357 Magnum Revolver - Blued Finish, Classic Early Production

For sale: Tough, proven Ruger GP100 double-action revolver chambered in .357 Magnum. This heavy-duty wheelgun, built on Ruger’s legendary large-frame design, succeeded the Security-Six with enhanced durability for heavy magnum loads—perfect for range work, home defense, or field use.

•  Caliber: .357 Magnum (safely shoots .38 Special for lighter practice)

•  Barrel Length: 4.2 inches (balanced sweet spot for accuracy, recoil control, and handling)

•  Capacity: 6 rounds

•  Action: Double-action/single-action with transfer-bar safety mechanism

•  Finish: Blued steel (shows attractive age-appropriate patina, light handling marks, and honest wear—no heavy pitting or abuse visible)

•  Sights: Adjustable rear sight, fixed front ramp

•  Grips: Textured black rubber grips (secure and comfortable, factory-style for excellent control under recoil)

•  Condition: Very good to excellent for its vintage—tight timing and lockup, smooth trigger pull, clean bore and chambers. Mechanically sound and ready to shoot; cosmetic wear consistent with normal use over the years.

Introduced in 1985 as Ruger’s beefed-up evolution of the Security-Six, the GP100 features a thicker frame, full-length ejector shroud, and heavier construction to handle unlimited +P and full-power .357 loads without the frame stretching issues seen in some competitors. Early Southport, Conn. markings indicate desirable pre-2000s production. Built like a tank—many owners call it the “indestructible” .357.
