But nice if you're walking a lot and shooting only a little. Only problem is, you go that light, then anything heavier than an ounce at modest speed and the recoil will get your attention.
I had a Lindner Daly Featherweight a bit lighter than that. Can't recall ever touching off any of my Gamebore 1 1/16 oz field loads in it. Let alone anything we'd put through an American 12, like a 1 1/4 oz Super X--which is a whole lot lighter than some of the pheasant loads they're pushing these days.
