Yes, there are. In some of the abandoned shacks in the game world during the story, you might find a free gun or two. These shacks are often off the beaten path.
Sure, there are hidden places. One such place could be some of the caves that you come across during the story. These caves may have been used by outlaws before and could contain a free gun among other loot. Another place could be the ruins of old forts. They may have been looted long ago, but there's still a chance of finding a free firearm if you search carefully.
There are indeed hidden places for free guns in the RDR2 story. For example, certain graveyards in the game world might have something hidden. It could be that a gun was buried with a deceased outlaw and if you're lucky while exploring the graveyard, you can unearth a free gun. Also, there are some remote cabins deep in the woods that may hold a free weapon. These are often places that are not easily discovered but are worth exploring if you're looking for free guns.
