Gun humor: what caliber for Cylons?

cx4 storm for cylons

Yesterday in the Space Gun Showdown the Beretta Cx4 Storm edged out the FN P90 as the more practical choice in the real world. I always thought it was amusing watching BSG that their guns of choice for shooting 8 foot tall killer robots were 5.7 pistols with underbarrel “grenade” launchers, and a pistol caliber carbine. I suppose that’s why they call it “fiction” though.
