With one big attack, it's either hit and roll all the dice, or miss and roll none.

With two smaller attacks, I still have a good chance of getting half of the damage through, which is often enough to kill.

Well let's check the odds here. We'll say 2 Size 1 Guns versus 1 Size 2 Gun, standard minifig versus minifig.

Size 1 Gun: 3CP Use:3 Rng:69" Dmg:1d6

Size 2 Gun: 6CP Use:4 Rng:10" Dmg:2d6

Firing two 1" Guns, we miss 1/9 of the time, hit with one gun 4/9 of the time, and hit with both guns 4/9 of the time.

Of the shots that hit once, we have a 1/3 chance to kill a minifig target. Of the shots that hit twice, we have a 5/69 chance.

Total chance of killing a minifig within five inches: 52%.

Firing one 2" Gun, we miss 50% of the time, hit 50% of the time.

Of the shots that hit once, we have a 5/69 chance to kill a minifig target.

Total chance of killing a minifig within ten inches: 42%. Not a huge difference, and double the range.

The lone minifig target within 5" is the most generous scenario. Take a minifig in Heavy Armor, or one standing further away, or a Vehicle with an armor rating in d10s, and you see the dual smaller guns lose effectiveness much more quickly than the single larger gun.
