What ammo should i get?

So I just purchased an sp5. can't afford the suppressor yet. had to get rails, sights, etc. anyways i plan on getting it stamped and going quiet. in the meantime do you recommend I run regular ammo out of this? should I use subsonic with a suppressor? are hollow points recommended or not out of a gun like this.. What ammo are you guys running on this gun?

hoping to get a few recommendations and trying them out myself, thanks
