I recently started using my first IWB leather holster. The mouth of the holster is reinforced to make one handed holstering easier. I read somewhere (FAQ of some holster maker's website I think) that it is bad to wear an empty leather IWB holster with a tightened belt. When I drive, I transfer my pistol to a holster that is mounted to my car seat because I can't draw from my right hip while I'm in the car. Do you think that it is a problem for the shape of the holster to leave it empty under a normal fitting belt?
