John M. Browning is undoubtedly the foremost gun designer in history, boasting an unmatched legacy of prolific invention spanning a wide array of firearms. From the iconic single-shot rifle to the revered model 94 lever action rifle, from the groundbreaking model 1911 handgun to the formidable M2 .50 Cal machine gun, and not to forget the revolutionary Auto-5 shotgun, Browning creations have solidified his reputation as a visionary who crafted durable and reliable arms for both hunting and global security. Among his illustrious designs, the superposed shotgun holds a special and cherished place. Despite Browning passing before its production, this masterpiece remains one of his most beloved and successful creations, earning admiration from shotgun enthusiasts across the globe. While the idea of stacking barrels on top of each other wasn't entirely new, the superposed emerged as the first commercially viable over-and-under shotgun. Browning, a passionate shotgun enthusiast, envisioned a double-barrel shotgun with a single sighting plane, a single selective trigger, and a dependable mechanism that would outshine the side-by-side models of its era. Applying the same ingenious approach that marked his other innovations, Browning gave birth to the superposed, a testament to his ingenuity. The result, a robust and exceptionally reliable firearm that, once again, left an indelible mark on history.
