Chiappa CF340182: A 10-shot version of the classic Single Action chambered in 17HMR. This model has a 7.5\" long barrel with adjustable sights. One of the most accurate reproductions of the 1873 Single Action. While maintaining the true to form classic design, this Single Action revolver is a hybrid of modern technology and manufacturing with the feel of the Old West. This revolver is crafted with a steel rifled barrel, with most of the mechanism and components constructed from a special formulated alloy that offers greater ductility and flexibility assuring long lasting reliability and durability.
