Snaphaunce Lock

Timeline

1. c. 1555–1570Northwest European firearms workshops · Northwest EuropeIn the era when matchlocks and wheellocks coexisted, craftsmen tried replacing the match and pyrite wheel with flint striking a steel. Early snaplocks still required the pan cover to be opened by hand; the snaphaunce combined the wheellock's automatic cover opening with a horizontal sear, allowing the priming powder to stay dry while cocked. This reduced misfires in cavalry and maritime use, though half-cock safety remained imperfect.
2. 1568–1584Scotland and England · British IslesWeapons history research by Claude Blair and others indicates Scotland had a snaphaunce manufacturing industry by at least 1568, with considerable output by 1575; England has archival records of multiple cases of "snaphance" shipped to Ireland in 1580, plus a dated 1584 firearm. Hakluyt's voyages also mention deaths from snaphaunce misfires during circumnavigations of the 1580s, showing the mechanism had gone to sea with fleets.
3. 1600–1650Western European and Mediterranean firearms markets · Western EuropeIn the first half of the 17th century, snaphaunces, Iberian miquelet locks, and early dog locks coexisted. Cavalry could pre-load multiple pistols without tending a match; infantry still widely used matchlocks due to cost and reliability. The term "snaphance" only becomes common in Dutch sources around 1619, so the mechanism should not simply be described as "invented in the Netherlands in the 1570s."
4. c. 1610–1680France · FranceThe true flintlock combined the striking steel and pan cover into one piece, automatically uncovering the pan on firing, with reliable half-cock safety, fewer parts, and better suitability for standardization. In the late 17th century European armies switched to flintlocks, and the snaphaunce left front-line service; its historical position was the transitional lock between the wheellock and the true flintlock.
