Federal, 'Champion' will work just fine. I've got a standard weight recoil spring in my G-19; and I go through, about, a thousand rounds of, 'Wal-Mart's finest 9mm ammo' every month.
Make sure you bring an open-topped; non-locking; and, preferably, Kydex holster; a strong gun belt; as many as eight magazines; and up to 4 magazine holders.
ADDED: Oh, yeah! A little thing like an Uplula will make life much easier for you.
