How can I make this grip texture more comfortable

I bought a S&W M&P 2.0. The grip texture feels great in my hand but not so great when I'm carrying AIWB and it's rubbing on my belly for hours. The options I know I have:Wear an undershirt: Not ideal because I run hot and don't want to add another layer when the weather is hot.Sand the grip: I've already sanded the removable backstrap but the rest of the grip still rubs me raw. I don't want to sand the whole grip and make it look like crap in case I decide to sell or trade it later.I've already tried Talon grips. They work great on my CZ P10c but don't stick very well and look like shit on my M&P. They seem to peel off easily from this pistol.Any other ideas or products? I'm wary of adding a grip sleeve if it makes the grip feel like a 2x4. I like how the small and medium backstraps feel in my hand. Thanks in advance. via /r/CCW https://ift.tt/3GmMPmi
