If you\u2019ve ever been torn between building a compact or a full-size pistol, we just made your decision easy \u2014 get both.<\/p>\n

The GST-9 MOD100 \u201c2 Guns in 1\u201d Bundle<\/strong> gives you everything you need to run a G19-sized carry gun and convert it to a G17-length setup in minutes. The included Overbite Kit<\/strong> lets you extend the dust cover and front rail to support longer slides \u2014 no second frame, no extra paperwork, and no wasted money.<\/p>\n

This is the most modular Glock-compatible pistol platform on the market. Period.<\/p>\n

Here\u2019s What You\u2019re Getting:<\/strong><\/h3>\n
    \n
  • \n

    1x Fully Assembled GST-9 MOD100 Frame (G19-sized grip)<\/p>\n<\/li>\n

  • \n

    1x Overbite Kit (for G17, 19L, or 19X configurations) \u2013 Requires Gen 3 Glock 17 slide<\/p>\n<\/li>\n

  • \n

    Smith Defense Lower Parts Kit \u2014 installed by a certified armorer<\/p>\n<\/li>\n

  • \n

    Test-fired and backed by our lifetime warranty<\/p>\n<\/li>\n<\/ul>\n

    Why It Matters:<\/strong><\/h3>\n

    4-in-1 Modularity<\/strong>
    G19, 19X, 19L, or G17 \u2014 the MOD100 is built to adapt. This bundle unlocks full-size functionality with the same serialized frame.<\/p>\n

    No Corners Cut<\/strong>
    Premium internal components come pre-installed. That means a billet aluminum trigger shoe, polished trigger bar, extended mag release, slide lock, and slide stop \u2014 all tuned for smoother shooting and faster reloads.<\/p>\n

    Better Ergonomics by Design<\/strong>
    Gas pedals, undercut trigger guard, high beavertail, and flared magwell come standard. You\u2019ll feel the difference in every shot.<\/p>\n

    Duty-Grade Durability<\/strong>
    Stainless steel internal rails are 3x longer than OEM for added strength and better slide tracking.<\/p>\n

    Glock-Compatible and Aftermarket Ready<\/strong>
    Runs Glock 19 Gen 3 parts and accepts most holsters, slides, and accessories without issue.<\/p>\n
