Legislation is always a possibility. In my view a greater concern is that - if the balloon goes up - the military and LEO types will get priority for available armor (as they should) and it simply won’t be available to others.
Frankly, body armor from reputable manufacturers is all high quality stuff. Within equivalent price ranges, it’s all pretty close to the same. Keep in mind these manufacturers all buy the ballistic materials from the same sources.
Also the NIJ standards keep the playing field rather level.
In the past, body armor manufacturers were simply tailors. Nowadays they are spinning off into all sorts of strange hybrids and laminates of questionable value. Questionable not because they don’t work – they do, but because they really don’t seem to work appreciably better than vests made of one material. (The clear exception to this being vests that are both bullet and knife resistant.)
Each manufacturer will try to convince they have discovered some new material, combination of materials, process, etc. which allows them make the best, lightest, coolest, most comfortable, yada, yada … vest on the market. You should simply ignore such claims.
Second Chance is an excellent, highly reputable vendor. However, they are perhaps a little pricey compared to some of the other vendors. IMHO they charge a bit more since they go the full distance to try to insure your vest fits you.
Also, their non-ballistic materials and workmanship seems a little better than some. In some of their more expensive vests, you can actually get a Gore-Tex carrier.
Incidentally, just a personal opinion, but I’d avoid anything with Spectra in it since it doesn’t seem to handle high velocity rounds too well (though it definitely can meet NIJ standards).
While quite expensive, my first choice would be a vest made of Zyloflex (Second Chance’s trademark for this is Ultima).
This is probably one of those situations where it is: “better to have it and not need it, than to need it and not have it”.
