The Flintlock, sometimes called the French Lock was the last in the line of locks based on the flint. It was developed in France about 1615. Marin le Bourgeoys was given credit for designing it. The basic design became the standard for flintlocks and quickly replaced older firing mechanisms throughout Europe. Flintlocks had a "half cocked" position, which was the "safe" position since pulling the trigger from this position did not cause the gun to fire. Flintlock muskets were the mainstay of European armies between 1660 and 1840. It was replaced with the percussion cap system. (Wikipedia)
The first of the flint based locks was the Snaphance, the English Lock, the Dog Lock, the Miquelet Lock, then finally the French or Flintlock. Pirate Fashion is the only place in the world were you can get all type of locks from the matchlock to the percussion cap.
