Little did they know then, that their company would become one of the world’s most renowned manufacturers of small arms. Just seven years after constructing an industrial plant for building the most sophisticated wagons and railway cars, the three ambitious owners undertook a more serious venture. In part to a challenge from Switzerland’s Federal Ministry of Defense, the Swiss Wagon Factory entered the competition to develop a state-of-the-art rifle with the hopes the Swiss Army would adopt it. At his point, the Swiss Wagon Factory, with an order for 30,000 muzzle loading Prelaz-Burnand rifles in hand, changed the name of the company to the Swiss Industrial Company – Schweizerische Industrie-Gesellschaft, known worldwide as SIG. Fast-forward to the 20th century, in 1949, the SIG P49, the forerunner of the SIG P210 was developed for the Swiss Army and destined to become a legend on the battlefield as well as the competition field. That same year, the P220 made its appearance as the new pistol for the army, soon followed by the compact P230 for the Swiss Police. These pistols offered new features and levels of reliability never before seen in the industry. October 1, 2007 SIGARMS changed its name to SIG SAUER. The change reflected the vast worldwide growth in demand for Sig Sauer products. In response, the company more than tripled its work force in the next 30 months, invested 18 million US dollars in state-of-the-art manufacturing facilities and equipment, and significantly expanded its engineering base. The name change, coupled with major new product introductions in pistol and rifles, reflects the continued commitment to the high standards of production, service and innovation the Sig Sauer brand has always represented. The Herrington Arms HC320R Compensator is an amazing compensator that greatly reduces the vertical and horizontal recoil of your P320 with two finish options of FDE Cerakote or Black anodized to match your weapon color, this is easily one of the best upgrades for your P320 Raider platform that is also at an incredibly competitive price point.
