45 caliber bullets and our world's equivalent of Roland's original bullets are Long Colt. They are described multiple times as being 'comically large'. The guns are extraordinarily large by the standards of modern pistols. Others believe the guns came from same Kashamin pyramid that Arthur and his sword Excalibur have been entombed in others say they were a gift from the Dark Tower. However, there are many other legends regarding their origins, and some say the steel and sandalwood are not from Mid-World but brought from an alien world. The sandalwood grips of the gun have never lost their fragrance and near the muzzle of each gun can be seen scroll work which translates to 'White', which was Arthur's dinh mark. They were made using the melted down blue-grey steel of the sword, Excalibur, and have the rose, the sign of the Eld, engraved in the side. They have been passed down through the ages from Arthur Eld himself, down to Steven Deschain and ultimately Roland Deschain. The Sandalwood Guns are the guns of a true gunslinger.
