The service revolver model 1873 Chamelot-Delvigne was the first double-action revolver used by the French Army. It was produced by Manufacture d'armes de Saint-Étienne from 1873 to 1887 in about 337,000 copies. Although replaced by the Modele 1892 revolver, it was nevertheless widely used during the First World War, and issued to reserve units in 1940. The Resistance made widespread use of it during the Occupation. The model 1874, of which 35,000 were made, was an officer's version. It differs from the model 1873 by having a lighter structure and a darker finish. Many copies for civilian sale were made in France and Belgium. Both the 1873 and the 1874 use an 11mm cartridge which proved to have insufficient velocity. The weapons themselves were very reliable and resistant to damage. A Navy version was also produced. A more powerful cartridge was produced for this version, but production ceased and they turned to the regular ammunition when the stocks were depleted. The Chamelot-Delvigne 11mm Modele 1873 was adopted by the French army as a service revolver for non-commissioned officers. The Modele 1874 Revolver d'Officier was the version issued to officers. The differences between the two models included the following: the 1873 was finished in the white, whereas the 1874 had a fluted cylinder and a blued finish. The 1873 and 1874 were the first center-fire cartridge revolvers adopted by the French army. They had solid-frame, side-ejection, double-action mechanisms. The pistols were manufactured by the St. Etienne arsenal, which still continues to manufacture fine sporting arms. The design of the Chamelot-Delvigne revolvers became so popular that versions were adopted by the Belgian in 1871, Italian, and 1872 in Switzerland with the Model 1872 Revolver. Revolver Model 1872 The caliber of these French pistols was 11x17.8mmR. The French round was actually 0.47 mm larger than its German counterpart. The German round could be loaded and used in the French pistol, but French rounds would not chamber in the German pistol. The cartridge had a pointed lead bullet weighing 11 grams. The case length was 17.8 mm, which was rather on the short side. Reloading this cartridge could take some patience due to the shortness of the case. Military specifications called for black powder loads, replaced by a mild smokeless powder in the early twentieth century. Standard muzzle velocity was around 550 feet per second. The cylinder had a side-loading gate which pulled straight to the rear. The sight picture was a ball and v type and is easy to align. It could be difficult to stay on target when shooting double-action due to the stiffness of the action. There was certainly no danger of accidentally pulling the trigger double-action. Cleaning and disassembly were easy as the cylinder pin doubled as a screwdriver and all-purpose tool. Internal parts were finely machined and finished. The trigger, hammer, and several of the internal springs were straw-finished, a type of case-hardening hot oil finish. The French pistols began their service with the French army in the late 19th century and saw service all over the globe in French colonies. Many saw service in World War I when European armies finally realized how important pistols were in the trenches. The Chamelot-Delvigne finally ended its venerable service as a police sidearm in World War II.
