Ideas for weapon/attachments

Ok, so you know the breaching shotgun and the M320s, right?

Very simple concepts: the breaching shotgun gets added to the regular shotgun list to fill the role of "smaller, CQB-oriented shotgun with wider spread and lower toob count," but also stays as a long tactical, UNLESS you equip a shotgun, in which case its replaced by breaching shells you would chamber load into your shotgun of choice

As for the 320s, and by technicality, the breaching shotgun again, a new attachment you could do would be to swap your grip out for an underslung 320/203 or a masterkey, giving you quicker access to your long tacticals while still being a bit of a trade-off since no grips means no buffs, and naturally the underslung blooptoob or masterkey wouldn't be available on all the rifles due to lack of attachment points and/or size but still it would be a nice concept for all the other rifles/battle rifles
