I keep hearing this penetration argument...

Wouldn't this make the 5.56 better in a shoot house than 9mm?
But I guess in close-quarters live fire drills, the 9mm would be a better training round due to reduced chance of armor penetration in the even of an ND/AD.
Whats the deal with that? Some are always saying that the 9mm is going to be worse with that so it is therefore the reason that the MP5 or similar is now not being deamed as useful with CQB?
If that were the case wouldn't frangible rounds or similar specialty rounds just nullify that argument?
If you prefer the power and versatility of the 5.56 so be it, but that won't improve its performance in a very short barrel.
