The M17 is the <strong>full-size</strong> version (4.7&quot; barrel, 8.0&quot; overall length, 29.6 oz empty), while the M18 is the <strong>compact</strong> version (3.9&quot; barrel, 7.2&quot; overall length, 28.1 oz empty). Both pistols share the same Fire Control Unit (FCU), the same grip height and width, and 17-round standard magazines are <strong>fully interchangeable</strong>, as are the 21-round extended magazines. The U.S. Army fields the M17 as its primary sidearm; the Marine Corps chose the M18 — and by 2026 the smaller M18 has become the more widely issued of the two. In the airsoft world, VFC offers licensed 1:1 GBB replicas of both.</p>
