    Just put my first 100 rounds through this new barrel, and I couldn’t be more pleased. I wanted a US standard .578 x 28 threaded barrel when converting my HK45 to a suppressor host. Yes, the new barrel dropped right-in. No, it didn’t need any gun-smithing. Your mileage may vary. The .578 x 28 thread pitch is very well-machined, and spares me from having to purchase a differently-threaded suppressor piston (i.e. My 1911 is also threaded at .578 x 28). Thread protector is included. Green o-ring is included. Alles ist klar, Herr Kommissar.
