I like the factory wood on my Redhawk, but it would be perfect if the grips were narrowed a bit, and checkered. It is in 45 Colt and I do shoot some stout loads but I don't think it would be much worse than full house 44's in a S&W 629 with factory target grips.
If there is someone on the board that does this, I would lke to hear about their work.
