I just bought a Ruger P89 9mm pistol SE. I was wondering if anyone carries an extended barrel that I could get threaded for a silencer. I work for a company called AWC Systems Technologies and we build silencers and such, so I do not need a pre-threaded barrel. I have heard of a company that if I heard corectly is Federal Arms Corp (FAC) and supposedly they carry extended barrels.. I did a GOOGLE search for this and found nothing. Anyone have any ideas?
