Someone made a GM items model in the Steam Workshop. It has all the weapons and cosmetics. Just favourite it and when you next open SFM it will ask you to download it, click yes (It's really quick). Then to add it navigate to add model and select All Mods. then scroll down to workshop, items, scout, cc_fortunate_son_summer15, add it and centre it to your player model. I have used it in a couple of my posters if you want to have a look I'd be honoured.
