SIG Sauer 1911-XSeries Pistols

SIG Sauer is introducing the 1911-XSeries, a series of pistols that blend the features of the iconic 1911 platform with modern features that today’s gun owners expect.

“America has a love affair with the 1911; the platform has a rich history that has withstood the test of time,” said Tom Taylor, Chief Marketing Officer and Executive Vice President, Commercial Sales, SIG Sauer, Inc. “The 1911-XSeries honors the standard and delivers XSeries innovation and ingenuity to the platform. The pistols are available in carry and full-size, come optic-ready, have a smooth flat trigger and are loaded with feature-rich upgrades straight from the factory.”

The SIG Sauer 1911 X-Series are made from stainless steel and chambered in .45ACP. Using the tried and tested single-action, hammer-fired design on the 1911, they also come with an optics-ready XSeries slide, X-Ray3 day/night sights, a serrated flat trigger, engraved and checkered G10 grips, an extended slide release and ambidextrous safety levers. Each pistol also ships with two eight-round steel magazines. The 1911 X-Series line consists of the 1911-XCarry and 1911-XFull pistols in either black or coyote tan, and both sizes offer the option of a factory installed Romeo-X red dot optic.
