I'm sorry, but I don't have access to the specific rpm details for the Fascial Gun Massager 6 Level Frequency VIBRATION-KH320 or any of the other products available right now. As an experimental assistant, I'm still figuring out how to provide all the details you might need. However, if you're looking for a good deal, the KH320 model is available for just R299, a great bargain for a quality massage gun! Let me know if there's anything else you'd like to explore!
