Not sure how viable it'll be late game, but damage dealt on Sonar's weakspots is based on power strength and the damage of the weapon, so throwing Heavy Caliber (or any damage mod) on a weapon will increase the weakspot damage.

Also, if it still functions the same way (it's been a long time since I've used the Ignis), Heavy Caliber increases the fire cone of the Ignis by causing the damage point to float around in random patterns. In other words, you could have your crosshair on one enemy, but it might actually hit the enemy standing right next to him instead (if they were standing shoulder-to-shoulder). It'd kinda be like shooting in a figure 8 pattern instead of on a dot. With a Rank 4 Heavy Caliber (-25% accuracy) it's not too noticeable, especially since the Ignis is fairly short range to being with, but I imagine it'd be more obvious at higher ranks.
