Plasma Gun 438

Space Marines Portal Deathwatch

The weapon denoted 438 in the Deathwatch Armoury vaults is a plasma gun of ancient, pre-Heresy design, with a noticeably different muzzle casing than that of later patterns, and exposed cooling ducts.

While the gun is undeniably a powerful weapon, its provenance is entirely unknown. As such, many of the Deathwatch refuse to contemplate its use, for fear it has been in the hands of traitors.
