I have one of these. Another one I bought to possibly replace my daily - but I wore it once and threw back in the drawer.
If I need to conceal my small Beretta, I use it. It’s uncomfortable as hell though. Pinching, rubbing and generally making me hate the fact that I have to hide my right to carry from a-hole libs who seem to have more control over my wardrobe than I do.
The whole IWB just irritates me and makes me hate about half of the country.
I wear mine OWB. I too dislike IWB.
