FROM WIKIPEDIA
The Ruger No. 1 is a single-shot rifle introduced and manufactured by Sturm, Ruger & Co. since 1967. it is designed with a Farquharson-style hammerless falling-block action, where an underlever lowers the breechblock to expose the chamber and allow cartridge loading, and closing the lever sets the rifle in battery and also cocks the hammer. A shotgun-style tang safety secures the hammer and sear.
