One more AR question: hammer pivot pin...

I've finished putting my lower receiver together except the buffer tube and that should be here tomorrow. I put a Geiselle SSA-E trigger in it (and it is sweet too!). Anyhow, I see the hammer spring engages the trigger pin and captures it, but is there nothing to keep the hammer pin from pushing out other than friction and spring pressure?
