1911 help

Ok so my dad got a us army 1911 auto loader, and we decided to try it out at the range. We put 71 rounds through before he had to leave and at home I was asked to clean it. I took it apart and the ejector rod(I think thats its name) popped off when it never came off when I cleaned it before shooting.
This is it with the rod off.


This is what it was like before.


Now I thought it was supposed to do that at first untill it I looked at it closer, and it looks like the pin broke on the front have in this pic.


My question is, is it safe to use as is? If not where would a good place be to get a replacement part that wont break after 71 rounds? And also can I install the part myself? Any and all info would be greatly appreciated. Thank you for your time.

p.s. Sorry for the blurry photos, big hands small camera

Well I dont like sendin it in to the factory unless I have to So I was wonderin if its possible to buy a replacement part and fix it myself, or have a gunsmith fix it instead.

I thought as much, I'll try the gunsmith first. Thank you for all your help guys.
