I’m a fan of IWB carry. As a bit of context, I have a job where I have to fly on commercial flights while armed with a full-size handgun. Concealment is a big issue and I have to be able to draw and re-holster one-handed. I’ve tried lots of holster options, and have landed on a kydex IWB holster made by a company called Cascadia Concealment. It retains the gun well, doesn’t collapse, and is comfortable enough to fly or drive all day and it doesn’t bother me. They cost in the neighborhood of $50-$60. Wish I could figure out how to post pictures.
