One of S&W's finest revolvers. Introduced in 1955 as the S&W Model 1955 45ACP Target rev, it was renamed the S&W Model 25-2 in 1957. It continued in production until 1999(?).
It is a continuation of the original 45 ACP revolver, the S&W Model 1917 and is rifled to shoot hardball ammunition or handloaded equivalent. Lead can also be quite accurate if sized to the cylinder throats.
I like them, a lot.
