A doglock is a type of lock for firearms that preceded the 'true' flintlock in fusils, muskets, and pistols in the 17th century.

A snaphance or snaphaunce is a type of lock for firing a gun or is a gun using that mechanism.

Miquelet Lock is a modern term used by collectors and curators, largely in the English-speaking world, that is widely applied to a distinctive form of snaplock, originally as a flint-against-steel ignition form, prevalent in Spain and Portugal, Italy, the Balkans, North Africa, the Ottoman Empire and throughout Spain's colonies from the late 16th to the mid 19th centuries.
