What’s Included
- High Standard Sentinel R-101 revolver
Frame marked R-101, this Sentinel pairs an anodized aluminum alloy frame with a blued steel 6-inch barrel and 9-shot fluted cylinder, keeping weight around 25.4 oz with an overall length of approximately 11 inches. The configuration reflects late-1950s U.S. production and the model’s emphasis on light weight with solid steel working components.
The action is double-action/single-action with an exposed hammer and a smooth trigger. The revolver uses a forward-pull ejector-rod cylinder release and a hole-type cylinder ratchet, both characteristic mechanical details of the Sentinel line.
Sights are straightforward and practical: a ramped front sight with a red insert for visibility and a square-notch rear sight cut into the topstrap. These factory-style sights complement the 6-inch barrel length for steady sight alignment.
Original-style brown checkered plastic grips feature a diamond motif and the Hi-Standard Sentinel eagle medallion, matching the period look. The blued steel barrel and cylinder contrast with the anodized alloy frame for a classic two-finish appearance.
