Standard Model 1859 pictured. The Berdan Special Version (not pictured) was a double set trigger model of the Sharps rifle without the lever catch.
Hiram Berdan was a successful engineer and inventor before the Civil War. With the commencement of the war, Berdan was permitted to organize units of sharpshooters, which would consist of the most accomplished marksman from the Northern states. The result was Berdan's 1st and 2nd regiments of U.S. Sharpshooters. These units soon became legendary for their expert marksmanship and respectable battle record. From 1862, most of Berdan's men were armed with Sharps rifles. These were breech-loading rifles that were easily and quickly loaded. Furthermore, they proved to fire accurately and became the favorite weapon of the men.
