This GP100 is the seven-shot variant, identified by Ruger as Model 1771 (SKU 01771). The cylinder uses a push-button release and is fluted with seven chambers, offering added capacity while maintaining the GP100’s familiar form factor.
The 4.2-inch barrel is heavy with a full underlug and is made of stainless steel, matching the investment-cast stainless frame and cylinder. The brushed/satin stainless finish presents a clean, durable appearance, and the Ruger phoenix logo is present.
Sighting is handled by adjustable iron sights: a black square-notch rear paired with a green fiber-optic ramp front for a bright, easy-to-acquire aiming point. The revolver operates in double-action/single-action and incorporates Ruger’s transfer-bar safety system.
The modular grip frame is fitted with black rubber grips and smooth hardwood inserts, providing a secure hold with a classic Ruger GP100 aesthetic. This example was manufactured in 2019 and includes the factory case labeled with the matching serial and SKU 01771.
