100 years of tradition. Sig Sauer pays tribute to the father of the modern self-loading pistol with maximum quality standards: minimal tolerances, extreme functional reliability, perfectly treated surfaces, and match-grade trigger characterize our 1911 in .45 ACP and 9x19. The Stainless Target model also features a skeletonized hammer for faster shot release, an ambidextrous safety lever, and a SAO trigger.
