I just put together a beautiful Nelson 22 conversion for one of my 1911's. What a great kit. It happens to have a threaded barrel for a barrel weight/brake. It would also thread on a silencer. We're now up to 159 co-sponsors on HR 367. They just keep dribbling in...man, I wish they would just get this done. I'm getting writers cramps sending letters to my congressmen and senators.
