Origin

From the late-1700s or earlier, the term sure fire was used to refer to gunpowder that was sure to light or guns that were sure to fire. Early guns were notoriously unreliable, so a weapon that was guaranteed to fire was an important advance, so important that it led to the term being taken up into general use, by the mid-1800s, for anything that is a ‘sure thing.’
