If the .44DA was the "cutting edge" of the 19th century, somebody forgot to tell the gun buying/shooting public. It took S&W over 20 years after they were made, to clean them all out of the vault. They even tried the design with a .38/40 caliber and that really struck out! I have a .44DA in .44S&W Special caliber, probably a test gun to see if the obsolete top break design could stand a .44 Spl. round. Smokeless powders were just around the corner and the top break design had seen it's day. The cutting edge was the Hand Ejector design of the 1890s that lead to the M&P K frames & the Triple Locks.
