due relatively low recoil of a handgun firing greentips at a fixed spot

A "fixed spot"? How is this achieved? Do you glue the handgun's muzzle to a spot on the vest? That's the only way you'll get that kind of repeatable impact.

So, my hypothesis is that a handgun shooting a greentip bullet rapid fire might penetrate a level III, while 'even' higher recoil rifles firing rapid fire could not, due rifle rise; thus I was suggesting another reason to ban the greentip.

Now your contention is clear -- it was not clear before, due to your vagueness and inaccurate word choices. However, your contention is still nonsense. It is virtually impossible to get that level of accuracy at speed from a .223 handgun, even at point blank distances. You're talking about "one ragged hole" accuracy, a Holy Grail even for scoped rifle shooters. The notion that someone could do that in a combat situation beggars belief. One pictures the assailant telling the police officer to hold still and stop shooting back so that he (the assailant) can line up his next shot. And even with these mythical three shots in rapid sequence, the notion that the armor would be compromised is baseless speculation. No, if this is what you're basing your ban-support on, your case is very, very weak.

I believe it's a peculiarity after hitting a soft target & short travelling, due the canellure (is it?). Hitting something hard might compress the bullet rendering it less inclined to fragment.

So your contention is that the bullet will fragment less on impact with a hard target than it does on impact with a soft target? Peculiar indeed. Remember that we're not talking about hollowpoints here. Do you have a reference for this? Perhaps you're thinking of the legendary "tumbling" of the .223 round on contact with a soft target, something that wouldn't be an issue with a hard target.
