The Ruger LC9 Conversion Kit lets you transform your LC380 or LC380CA pistol into a 9mm Luger shooter without buying a whole new gun. This genuine Ruger factory kit includes everything you need: a blued steel barrel and slide assembly, a 7-round magazine, and clear conversion instructions. It's a practical way to expand your carry or backup gun's capabilities if you already run 9mm ammunition elsewhere in your collection.
Converting between .380 and 9mm with a factory kit means you get Ruger's engineering and quality control—no guessing, no sketchy parts-bin builds. The blued steel finish matches classic Ruger aesthetics and holds up to regular carry and use. Note that this kit is designed specifically for the LC380 and LC380CA models; it won't fit the LCP platform.
Whether you're a shooter who wants more ballistic options from a single pistol or someone building out a practical defensive battery, this conversion kit bridges that gap affordably. The included magazine gives you a complete package right out of the box.
