You can only fire one weapon during the attack phase. Either you choose your primary weapon or you choose the heavy laser cannon. If you fire the heavy laser cannon you will have to turn all crits into hits after your initial roll. The advantage is that you have 4 attack dice and since this is a secondary weapon the defender will not get any range bonus at range 3.

The disadvantage doesn't really matter because it is still a damage and you can use a target lock to reroll your blanks and focus results into hits and crits, the crits stay after the reroll, so will any other stuff that helps turn hits into crits like Mercenary Copilot or Calculation.
