Overview

About the Sig Sauer M18

The Sig Sauer M18 is the compact counterpart to the M17, also based on the U.S. military’s adopted sidearm, with a shorter 3.9" barrel, a 10-round magazine, Siglite night sights, and Coyote tan finish. It’s the same military-pattern pistol in a more concealable package than the full-size M17. Ask Miami Guns whether they currently have the M17 or the M18 in stock.

Sig Sauer

Sig Sauer traces its roots to Swiss and German gunmaking traditions going back over a century, with its modern U.S. operations headquartered in New Hampshire. The P320 serves as the U.S. military's official M17/M18 sidearm, and Sig's broader lineup spans everyday-carry pistols, precision rifles, and modern sporting rifles.
