French Design. Caplock or Percussion Lock pistols were so called because the lock system causes a percussion cap to be struck by the hammer when the trigger is pulled. Powder inside the cap ignites and this in turn ignites the main powder charge, which propels a lead ball from the barrel. Most (though not all) caplock firearms were loaded from the muzzle of the gun (muzzleloaders). The Caplock was a great improvement over the flintlock as it was less susceptible to weather-related misfires. The original of this pistol was made in Brescia, Italy in about 1825. This non-firing version is accurately detailed and shows typical Italian craftsmanship a great costume or conversation piece.
