Don't sweat stuff like that. The purpose of a forend is to keep the barrels on, not to grab hold of. You should be holding the barrels themselves and the splinter facilitates this.

If they get too hot use a glove or a barrel shield.

I know it's a personal taste but beavertail forends really look clunky to me as opposed to the sleek appearance of an English stock in combo with a splinter forend.
