I have a SW MP 9mm CORE 5" barrel. I am interested at a compensator. I looked at Welcome to Speed Shooter Specialties and found a 3 port carver cut type of compensator. Has anyone used one on a threaded barrel. I have to buy a barrel and the compensator. I would like to know how much this will reduce recoil. I also want to make Minor power factor. Not interested in Major power factor with the CORE. Any advised ???
