Since it could be in the primary slot, why not have it be the Sticky bomb version of the Loose Cannon bombs?

As in have fuse time to cook, plus it sticks to walls, to compensate for not being the secondary?

I think this would be a good primary weapon, especially with the Loose Cannon style stats.

And I see people say that it can be a Black box, maybe 25 HP on kill for 50HP overheal?
