Three 357 Magnum revolvers were stolen from Dekaise, including one Ruger and two Smith & Wessons.
Remington 357 Mag Metal Point bullets were used.
357 Magnum bullets are more powerful than a 9mm or a .38. A revolver doesn't jam like a pistol does; it's more reliable. However, it has much less ammo capacity and takes longer to load. The 357 Magnum also has more recoil and more muzzle blast.
