Lasguns - Dune: Awakening Database

Though the Imperium has forbidden the import of lasguns without a safety mechanism, there are other alternatives for bringing a lasgun to Arrakis. The smugglers have access to an entire offworld arsenal of lasguns that do not include the safety mechanisms put in place by the Landsraad council.
Unfortunately, this Unique lasgun is not one of them. It’s just a regular lasgun with the serial numbers filed off.

When a lasgun contacted a hot shield in Carthag, it was a disaster. Thousands died in the ensuing nuclear blast and the city was leveled.

Due to the devastating loss of life and spice production capacity, all lasguns imported to Arrakis are now fitted with a safety mechanism that immediately shuts them off if they are targeting a Holtzman shield, including this Unique model.
