General Marie-Théodore de Rumigny

“Compelled by my duty to deal with firearms, my taste for hunting has led me to seek out the invention that offered me the most certain advantages. I declare that after numerous trials, Mr. Lefaucheux’s gun, with the base applied to cartridges, has seemed to me the most perfect of those that have been invented to this date.”

Paris, November 17, 1834.

The Lefaucheux Legacy: A Timeline of Innovation

Trace the pivotal milestones in the life of Casimir Lefaucheux, from his birth to his groundbreaking contributions to firearms technology, unfolding a legacy of ingenuity.

Heritage Begins: Birth of Casimir Lefaucheux

In Bonnétable, France, a visionary in firearm engineering, Casimir Lefaucheux, was born. His innovations would shape the future of firearms.

The exact timing of Casimir Lefaucheux’s apprenticeship initiation at the Pauly workshops is not documented. Typically, during that historical period, apprenticeships began at ages 12 to 14. Pauly left his French operation for England in early 1814, so it’s possible that Lefaucheux could have apprenticed under Pauly himself or started later when Henri Roux took the helm.

Casimir Lefaucheux’s 1835 patent laid the groundwork for modern ammunition with the pinfire cartridge system. This invention streamlined the firing process by integrating the primer into the cartridge, featuring a striking pin for rapid ignition. A milestone in firearms, it significantly advanced the efficiency and safety of loading and shooting mechanisms.

Alexandre Dumas

“I have bought from Mr. Lefaucheux a carbine and a gun; besides the advantages of a quick loading, I have found in them a more accurate and longer range, especially with bullets. The carbine, much less heavy, much easier to load than the Swiss carbines, has given me in two or three Cantons, over the shooters of these cantons, an advantage that I attribute entirely to the superiority of the system.”

Alexandre Dumas,
Man of letters.

(Author of The Count of Monte Cristo, The Three Musketeers, etc)

These endorsements from distinguished individuals of the past provide a testament to the enduring quality and innovation that define Lefaucheux’s contributions to firearms engineering and artistry.

I have also been using Mr. Lefaucheux’s guns for a long time, and I have always been satisfied with them; but the new improvements that this weapon has received make it even more convenient and leave nothing more to be desired, even in terms of lightness and elegance.

F. Nicod, deputy.

For more than five years that I have been using Mr. Lefaucheux’s gun, I have only had praise for it in all respects; I do not see what could be invented that is better and more convenient in this category, especially since the improvement made to this weapon by means of the bases added to the cartridges, which gives it more range, and prevents any kind of spitting.

Count Lanjuinais, peer of France

For thirty-five years that I have been hunting, I have had guns from Paris, Versailles, Maubeuge, and Saint-Étienne; I have used all systems, but, as a great hunter and arms enthusiast, I must say that Mr. Lefaucheux’s gun is, to date, the best I have seen; it is very quick to load, the safest and the most convenient for all kinds of hunting.

Lieutenant Colonel, L. Lorry
