Is it possible to loot a proper gun on the first island? I found a vendor who sells it but I am short on cash!
No, there are very few lootable guns in the game. Also, pistols are simply off hand weapons (press E to use one). Bigger guns like shotguns and muskets are actual weapons, but you have to join the Inquisition to get access to the good stuff. The whole fire arms tree is pointless unless you do.
Edit, figured I might add a little spoiler in case you really want a pistol:
You get one from one of the pirates you fight at the start of the 2nd island.
