Example data pack/resource pack for adding guns doesn't render the gun, shows a stick

I'm having issues figuring out why the gun texture isn't showing up, it's just a strangely positioned stick. The laser texture and the firing sounds in the resource pack get applied, so the resource pack is applied, and the data pack is active because i'm able to shoot bullets out of a stick. The laser gun model isn't applied. Any idea why? I've been racking my brain trying to figure it out for over a week

Link to your post on Discord where you shared the resource pack and data pack: https://discord.com/channels/336389026586165261/490398075131658271/955052467740082187

laser stick that should be a laser gun:

I should add that when I add the laser gun to a quest reward, it shows the laser gun, but when I get the gun it's a stick which leads me to believe it's broken?
