Is there a need for a gun belt when carrying IWB?

I have a G26 that I have been carrying for about a year. I love the gun and it feels well when I carry it in the right positions. But I was wondering if it was generally recommended to use a gun belt when carrying IWB? I always wear a leather belt, but it's just a generic belt. via /r/CCW https://ift.tt/2ocgKqo
