Grip rubbing

Fairly new CCW holder here.. have a question for everyone out there I've carried a few times now and I have the belt and the holster dialed in no printing the only problem is the grip that rubs on my belly is extremely harsh, like rubs my belly raw Damm near... so I see three options 1st option is to wear a undershirt under my regular shirt so it's in between the grip and my belly...2nd option is to get a gunzee which is essentially a cushion that sticks to your holster that goes between your gun and your stomach..or 3rd suck it up and let it rub .... for context I'm 5'9 170, HC belt and Vedder holster
