Recommendations on my first gold weapon?

Reinhardt! It's the biggest one. Bigger is better!!

My first was Ana because I was maining her at the time, but honestly just go for what you play the most lol.

Your first gold weapon should be whatever you feel you do best at. A gold weapon is to show you're good at that character and players would most likely give up that character because you have that character's weapon golden. Try some other characters to see if you like them.

The gold is up to you lol if you want to get one to meme gettorbjorn gold gun.
