The 2.0 grip texture is too sharp for some. Easily adapted to whatever you need.

Sand it in stages until you get where it is comfortable, as has been suggested in dozens of posts.

Put a grip sleeve on it, which will make it bigger, and that may be an advantage.

Use grip tape. Again, bigger.

Or go with the 1.0 that some complain is not grippy enough, so it might need to be enhanced too.

As grips get more grippy, they tend to snag covering garments, especially a t-shirt, and potentially print. They wear the garment faster. They can interfere with moving the covering garment out of the way.

You need a comfortable but secure grip on a CCW. These two characteristics are not mutually exclusive, but you will likely have to compromise and customize a bit to get what works for you.
