I spent the past week creating a system that gives you ammo on account of weather you have any clips left. And whilst the pistol is just a redstone buffed bow, it has a smooth and realistic feel (especially when combined with a resource pack). Works in 14w33a and onwards. Weekly snapshot testing will take place.
