In general, models with more than 1 Ranged weapon may only fire one per turn. However, multiple exceptions to this occur, so be sure to check. If I may ask, do you have a Specific model in mind?
For Example: Seraphim have 2 bolt pistols, and can fire them both at once as a twin linked bolt pistol (or inferno or hand flamer)
Space Marines, however, have both bolter and bolt pistol, and can only fire one.
