Used SIG Sauer Values 2026:
Every Model, Every Caliber.
SIG Sauer's roots go back to Swiss Industrial Company (SIG) in 1853 and J.P. Sauer & Sohn in 1751 — the two firms partnered in 1976 to produce the P220. Today SIG Sauer is the U.S. military's standard sidearm contractor (M17 / M18 / MHS program, adopted 2017) and produces the dominant carry-pistol family (P365), one of the most-adopted duty pistols (P320), the gold-standard service-grade DA/SA (P226 / P229), and an expanding rifle line (MCX, MPX, M400, Cross). Limited-edition Legion series command meaningful premiums.
