You want to have the best shotgun early in RDR2? We’ll show you where to find one of the best weapons in the game, the semi-automatic shotgun.
West of Wallace Station you will find a small cabin, Watson’s Cabin. In the hut you meet an old lady, talk to her and wait until she sends you to the basement, then go down to the back room and through the hatch. There you will find the semi-automatic shotgun.
