A wood stock with a gloss finish is certainly more delicate than a matte or oiled finish. I far prefer an oiled finish over a glossy one. An oil finish is repairable with some fine abrassive (400 grit paper, 0000 steel wool,etc) to blend out the scratch, followed by oil, wax, or scratch hider. A high-gloss finish can not be fixed in this manner.
I have seen M1 Garands that went through combat service in WWII and Korea, and the stocks on those were not too bad. I don't see how hunting can be more abusive than combat.
