"I complained to my retired LEO buddy about the chafing with the Sig and how I'd been advised that it would 'get better' with age. He said, "yeah, about the time you've chafed a hole in your belly and your intestines are leaking out!" Ha ha. What a jokester. (Maybe he was right.)" I think I solved the summer chafing issue this past year when I bought a package of "Tank top" type undershirts - sleeveless, light weight garments that I wear UNDER my holster, and cover it all with a regular T shirt.
