Well if it does not fire a single round without the magazine then it must not fires multiple rounds without it either.
How many lives do you think it saves by them putting those warnings all over the gun?
What if it was modified to fire without a mag? Its much better to only (if you have to) put a warning on when it does fire without a mag like the M&P that comes both ways.
And of course they have to make the text so deep that to take it off would require major work.
Only thing that should be that deep is the manufacturers logo, name, model and serial number. The rest we don't need.
