So I just realized while cleaning that the back of the frame has a broken piece off. Do i have to send it in or can i still fire like this

Don't worry about it. That's how it's supposed to look like.

Thank you. probably a stupid question but its my first firearm just want to make sure i didnt mess anything up. thanks again

You're very welcome. There are no stupid questions.
It's always better to ask if you're not sure than running into trouble or worse, hurting yourself or others.
