The Colt Army Special
The term "Army Special" moniker was a marketing ploy. No army ever officially adopted the revolver as a sidearm. In 1927, the Colt Army Special became the Colt Official Police with only a name change. This particular revolver is one I picked up at Kay Clark-Miculek's place for $275 a couple of years back. The prices have not changed drastically since then, but Here is a Range Report.
