I have the Twisted Industries Ruger LC9-22 conversion. Ive had this for a year or so now, and its a well made, reliable conversion. Twisted Industries now has threaded barrels available for these kits. Mine came in the mail today. The new barrels are stainless steel. The barrel needs a thread adapter to use a suppressor, and Twisted Industries also has the matching adapter for that purpose. The adapter TI sells is aluminum. I shot 30 rounds today with the new barrel, and my SilencerCo Stainless Sparrow, and it runs perfectly. No FTF or FTE. This is a neat little combo, and is one of the few DAO 22 suppressed pistols you will find. This kit DOES NOT work with the new Ruger STRIKER fired LC9s. It does work with the Ruger LC380.
