Lupara

The Lupara is a rare and considered the best weapon in the game (apart from the horrible ammo count). It is very inaccurate but fires multiple (9, to be specific) pellets of shrapnel (as a shotgun) which makes the chance of you hitting your target way higher and is (technically) the most accurate in the game. It only has 2 shots but its power makes up for that.
 * Real Life: The Lupara is a sawn-off shotgun used by hunters and criminal gangs.
