What’s Included
- Ruger GP100 .357 Magnum stainless steel revolver (4 inch, 6-round)
The GP100’s stainless steel, one-piece frame without a sideplate provides a rigid foundation. Ruger’s triple-locking cylinder design secures the cylinder at the front, rear, and bottom for consistent alignment. A left-side push-button latch offers straightforward, positive cylinder release.
The 4 inch heavy barrel with a full underlug adds forward balance. Sighting is handled by a green fiber-optic front ramp blade that is plunger-retained and interchangeable, paired with a fully adjustable square-notch rear sight for precise windage and elevation settings.
This revolver runs in double-action/single-action with a transfer-bar safety system. The exposed hammer with a checkered spur allows controlled single-action shots when desired. The six-shot cylinder has six flutes and is cut for .357 Magnum while also accommodating .38 Special and .38 Special +P.
Ergonomics come from a one-piece black rubber grip with inset hardwood panels, providing a secure hold and a classic appearance. The brushed/polished stainless finish and Ruger phoenix rollmark on the frame complete a durable, low-maintenance package suitable for sustained use.
