The weapon profiles themselves in no way change. Pathfinders are essentially armed with two shooting weapons: the markerlight, and the pulse carbine. The pulse carbine has an Assault 1 profile - you may therefore move and fire it. The markerlight, on the other hand, is Heavy 1, therefore you may not move and shoot it.
The fact that it's coincidentally strapped to the body of the carbine has no effect whatsoever on the rules.
Also, as normal, you may only use one of these two shooting attacks, you can't use both in the same turn.
