Gun Fanatic Achievement Not Working

[Brick]

I just got the handcannon, and the achievement still hasn't popped. Do I have to have every single weapon in a single playthrough in the campaign or is this just bugged?

You have to acquire ALL weapons in a single savefile.

So basically I have to start a new game and acquire every single one?

check the challenge to see how many you are missing.

If you have a finished game already you can do a new game plus on it, this way you will already carry all your stuff from the first round and receive the bonus weapons acquired.
If you didn't have the bonuses unlocked before starting a new round you will need to finish again the game to receive them or create a new game.

Important to note that, you need to acquire the gun in-game, not only unlocking it on the extras menu.
The handcannon will be added to the stash in every new round after it is acquired.

It says 28/29 but I have all models. Weird.

Usually the most commonly missed:
- Infinite RPG. You need to buy it in-game.
- Chicago sweeper.
- Hand Cannon.
- Matilda (purchase with spinels)

Thanks a lot. It was the Infinite RPG, although I'm more than sure I used it once before.

I actually kinda having this problem in my NG+ run to complete the achievement. The thing is you must equip the weapon or at least move it to the attach case. In my case, the primal knife is in the storage, then i move it out to the case or equip (i forgot) and i got the achievment.

You are welcome friend. Have a nice game.
