The absolute best?
I vote Sphinx 3000 series.
Sphinx Systems Limited is a small Swiss based manufacturer of high quality pistols used mainly by special forces, elite police units and sports shooters. The company has been in business since 1876. Sphinx is 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 manufactures all pistols in Switzerland, slides are made from solid billet steel, frames from casts, forgings or also from billet, and fits each pistol with high quality barrels. Each pistol part is machined to very close tolerances and assembled by Sphinx master gunsmiths.
All Sphinx pistols except the AT380 are shipped with an actual test target, which confirms the accuracy of each pistol.
Sphinx pistols are not mass produced and are fitted to tight tolerances, so Sphinx pistols are more expensive than mass produced products.
Historically imported to the United States, by SILE corporation, SPHINX products are now imported by SABRE Defence Industries.
Sphinx 3000 Series
A full and medium sized defense and sports CNC machined pistol made out of various metals such as stainless steel, aluminium and titanium. The Sphinx 3000 quickly displaced the legendary SIG P210 as the best Swiss made pistol, as the Sphinx 3000 offers the same accuracy and reliability combined with better ergonomics and twice the capacity for ammunition. The Sphinx 3000 was designed as a modern combat pistol with features like a Picatinny accessory rail, a low bore line, extended magazine release, various safety system options, various finishes, sights, pistol sizes and materials to choose from.
