The particle magnum is the standard sidearm of the Travelers. One is also carried by Ronon Dex. It is an energy weapon with settings for stun, kill, and incinerate. It is carried by the Alliance of Nations. The particle magnum has the appearance of a long-barreled revolver. The cylinder of the weapon is a power cell with a luminescent dome on the back. The cell has a finite amount of energy, but can be removed to recharge or replace it. The barrel of the gun has three small crystals of increasing size from bottom to top. The weapon has three settings: stun, kill, and incinerate. The toggle is on the barrel just in front of the cylinder, and the cylinder color changes to indicate the setting: red is for stun, white is for the other settings.
