No need to carry, but being hold for hours by police for identity
verification isn't much fun either.

Being held by police doesn't make it any easier to go and get the
passport from the drawer at home, either.

If your home is near where they check you (same city), they'll simply take
you to your home and there you show the papers.

If they catch you in Hamburg with your ID in Berlin, they can hold you
until they get someone in Berlin confirming your identity. And that can
take a bit of time.
