About the Handgun:
The Sphinx 2000 series is based on the Czech CZ-75 pistol. Improvements to the CZ design include a firing pin safety and slightly different barrel/slide locking system. Sphinx pistols are made in a wide variety of models and modifications, suitable for self-defense, police duty, and practical shooting under IPSC and IDPA rules. The Sphinx 2000 is a short recoil operated, locked breech pistol. The barrel is operated using a Browning cam system, and is locked to the slide by single lug via a large ejection port. Most 2000 models feature a Double Action (DA/SA) trigger with external hammer.
About the Manufacturer:
This was a Swiss based manufacturer of high quality pistols used mainly by special forces, elite police units and sports shooters. This machine-tool and engineering company started in the gunmaking business when it acquired gunmaker ITM of Solothurn in 1989, along with the rights to its handgun designs. Sphinx was best known for its ongoing development of the original Czech designed CZ 75 pistol, which has been evolved into the Sphinx 2000 and Sphinx 3000 designs. Sphinx pistols are were mass produced and were fitted to tight tolerances, so Sphinx pistols are more expensive than mass produced products.
The Swiss company KRISS Arms Group purchased Sphinx in November 2010. By 2012 KRISS Arms ceased production on all previous Sphinx handgun models and began development of the SDP line of handguns under the Sphinx brand.
KRISS USA is the North American extension of the Swiss based KRISS Arms Group. Product development, manufacturing, and distribution currently take place across the US, from Virginia to California.
About the Cartridge:
This cartridge was introduced along with the Luger semi-automatic pistol. The pistol and cartridge was first adopted by the German Navy in 1904 and then by the German Army in 1908. This cartridge has since been adopted by the military of practically every non-Communist power. It has become the most popular and widely-used handgun cartridge in the world. Performance wise, the 9mm cartridge has somewhat more power than the .38 Special but falls well short of the .357 Magnum.
