High Standard Sentinel for Sale

Founded: 1926

HQ: United States

The High Standard Sentinel is a double-action/single-action revolver in .22 Long Rifle, defined by its 9-shot cylinder. It stands out for lacking an external cylinder thumb-release, unlocking instead with a forward ejector-rod pull. On FirearmLand, High Standard Sentinel listings most often appear in .22 LR and .22 WMR.
