What's Included
- Revolver speedloader
The GP100 platform is built on carbon-steel components with a blued/black-oxide finish, including the frame and cylinder. The 4.2 inch barrel has a full underlug and a serrated rib, with the ejector rod fully shrouded for protection and smooth operation. This example was made in the United States in 1991.
The six-shot fluted cylinder uses Ruger’s triple-locking system for secure lockup. A left-side push-button cylinder latch provides straightforward unloading and reloading, and the coil-spring lockwork and modular grip peg reflect the model’s serviceable design.
The revolver operates in double-action/single-action with a spurred hammer and a smooth trigger. A transfer bar is fitted as a safety feature.
Targeting is handled by a pinned ramp front sight and a fully adjustable rear sight. The factory Ruger one-piece rubber grip with hardwood inserts provides a secure, hand-filling hold. A revolver speedloader is included.
