 It was possible to lower the Whitney hammer between cylinder chambers for safe carry, but without the Remington milled slot, the Whitney cylinder could possibly slip and rotate, allowing the hammer to strike a loaded, capped chamber and cause an accidental discharge.The Remington revolver permitted easy cylinder removal, allowing a quick reload with a spare pre-loaded cylinder; this being an advantage over other revolver designs of the time.It is, however, unlikely that this was common practice during the period.
