This is the real deal factory conversion straight from Ruger, built for owners of the LC3801 or LC380CA who want to add 9mm Luger into the mix without buying a second gun. Since the LC380 and LC9 were built on the same platform, swapping the barrel and slide is really all it takes to open up a new caliber option on a pistol you already know and trust.
The kit centers around a blued 9mm Luger barrel and matching slide assembly that drop right onto your existing LC380 frame. Because Ruger engineered these two pistols to share a common lower, there's no fitting, machining, or gunsmith work required. You're simply swapping upper assemblies to change what the gun feeds and fires.
Along with the blued barrel and slide, you get a 7+1 round 9mm magazine that includes the extended finger rest baseplate for a fuller grip. Ruger also throws in a printed instruction manual along with step by step conversion instructions, so you're not left guessing on reassembly or function checks once the new components are in place.
This kit is built specifically for the LC380 and LC380CA models and will not fit the LCP or LCP II. If you're not sure which pistol you own, checking the model stamp on the frame before ordering will save you a headache. Once installed, many owners find their sights stay properly zeroed after the switch, which speaks to how tightly Ruger dialed in the tolerances between the .380 and 9mm variants.
No, this kit is built specifically for the LC380 and LC380CA models. The LCP has a different frame profile and this barrel and slide assembly won't mate up correctly with it.
Most owners handle the swap themselves since the LC380 and LC9 share the same frame design. It's essentially the same process as a normal field strip and reassembly, just with the new barrel and slide going on instead of the originals.
Yes, the slide comes with sights already mounted and many owners report they stay properly zeroed right after the conversion. It's still smart to run a few rounds through and confirm point of impact before you consider it range ready.
This magazine is built specifically for the 9mm LC9 configuration and fits the shared LC380/LC9 magwell, so it won't drop into other Ruger models outside that platform. It does include the extended baseplate for a slightly longer grip and a touch more purchase.
