Charles Gabriel Petter (26 March 1880 – 7 July 1953) was a Swiss firearms designer.
Charles Petter, born in Lavey-Morcles, studied mechanical engineering in Bern and was a lieutenant in the infantry of the Swiss Army. He became an employee of Krupp in Essen, Germany. During World War I he served in the French Foreign Legion, where he obtained French citizenship and the rank of captain.
He received two French decorations, the Croix de Guerre and membership in the Legion of Honor. (He was made a French citizen by Presidential decree in 1916).
After that, he was director of the French branch of the Belgian company Armes Automatiques Lewis and consultant of the Société de Constructions Alsacienne Mécaniques (SACM) in Cholet.
Petter designed the Modèle 1935 pistol which had some of the same design elements as the John Browning M1911 such as the grooved slide and barrel which interlocked and recoiled together until a pivoting link lowered the barrel, thus unlocking the assembly and further rearward movement of the barrel and slide together, which after reaching the point of greatest movement would be returned to battery. Along the way the slide would strip a cartridge from the magazine and push it into the chamber just prior to the under barrel link forcing the barrel up into engagement with the slide, locking the action. Petter eliminated the barrel bushing and used a full length spring guide which had the effect of removing some of the inaccuracy from the M1911 design and increased functional reliability.
A unique feature of the system was an integrated fire control system. The trigger, hammer, mainspring, and sear assembly were contained in one unit. His design impressed SIG of Switzerland, who licensed it in order to produce their model 47/8 handgun (which became the Sig P210, now known as the Sig Sauer P210).
