My one is a little loose but it was loose the day he installed it. That ball was already drilled with a regular thumb and I had him put the switch grip in it. My others were all drilled with the switch grip and they are all pretty tight. But yeah, JR Raymond has a youtube video talking about loose inserts. Just a small piece of thumb tape around the insert near the bottom. If it's still too loose move the tape up towards the top more as he said the are slightly 'cone' shaped.
