I believe this is a shield you might consider. I could not find the prices on them. I am on board with your idea. Funny how we are so willing to have the offense but lack the defense. Shields were so widely used, and with guns it kind of diminished. Of corse the swat teams use them, and I would think that shows the usefulness of it. Yes they are room clearing, and what not. That does not mean this would not be a brilliant idea to have for a defensive situation like a home invasion, shtf. This small shield in the link seems like one of the best for this scenario. Small Ballistic Shield
Years ago i was writing an article (that i eventually sold to Guns n Ammo) on penetration in a modern home. During the research i conducted a series of tests where i shot simulated walls with various calibers to see what would penetrate. Since it was a foregone conclusion that 2 layers of sheetrock would stop nothing, i placed all shots thru the stud in the middle (no i did not shoot myself...i shot the wooden 2x4 between the sheetrock layers). Amazingly i was able to achieve penetration down to a 32 (which consistently penetrated half the stud before exiting sideways.)
So that tells you how much protection walls give you.
But to answer your original query; Years ago Masaad Ayoob was modelling a pretty cool fanny pack that had a kevlar shield that you could pull outta the bag with one hand. So the fanny pack would not only act as a vest, but it could hold a gun, phone, and cuffs. Pretty cool item, dunno if they still sell it though. Twas likely expensive.
Best suggestion is to teach your people to stay down until the shooting is done.
