Just installed a threaded SS 9mm Storm lake in my XD 40 service. Only problem, if it is a problem. The barrel is just a little loose. It sticks out past the slide about 3/4 of an inch. I can push it up or side-to-side about 1/32 of an inch. My 357sig aftermarket brl. And the factory Springfield 40 S&W brl. does not move hardly at all. I called and talked to a tech person at SL and they said that much movement was within tolerance. Haven't shot it yet might be fine.
