Vanilla Armor Expanded - Reduced bulletproof vest weight, increased bulk.
Vanilla Weapons Expanded - Add one-handed tag to sawed-off shotgun
Reasoning
While 10 is probably appropriate for a vest with a hard plate, the bulletproof vest is stated to be soft armor, so the weight has been reduced. Bulk also increased to something closer to other armor.
Sawed off stats were generated with the intention of making it 1-handed, I just forgot the tag first time around.
