Stalker 2: Heart of Chornobyl has an abundance of unique weapons in the game that are either modified or high-powered versions of their base variant. One of these unique weapons is the Texan, which is one of the best shotguns in the game due to its high rate of fire and amazing damage. Players can find this weapon in one of the late-game regions called Jupiter. So, you'll either get this weapon towards the end of the game, or you can visit Jupiter early by following the Stalker 2 Pripyat guide.
