There’s been a few posts about this recently, and I agree with you. Back in D1, 9 slots was enough for the amount of loot in-game, but now with all the stuff we have, 9 feels like nowhere near enough. Like someone else has said, third party apps will put your vault in your hands, but I think we should still be able to carry more than 9 per slot. 3-4 of each of mine is filled with an exotic, plus 3-4 regular use guns. Even if it’s just up to 12 per slot, I think it would be a good quality of life improvement for the game.
