What is the fastest firing rate for a submachine gun in Borderlands?

I'm looking for the fastest firing submachine gun in Borderlands. I'm willing to sacrifice accuracy, magazine size and element effects while maximizing the total bullets per second. Is there a fastest firing SMG gun, unique or otherwise? Or do artifacts generally overwhelm the basic firing rate?

Solution 1:

The double anarchy is by far the fastest firing SMG. Every 'shot' results in 4 bullets traveling to the target but expends only 2 rounds of ammo. I made this video to compare my double anarchy with a hellfire mentioned in Portali5t's answer. Note that even with a 82 round clip compared to 55, the double anarchy runs through the clip at a much faster rate.

The drawback to any gun with the anarchy mod is that its highly inaccurate, unless you find a good one with a high zooming scope.

And here are the comparative stats:

Solution 2:

Well, there is a 2 part answer to this: The Gasher is the fastest firing SMG type, but it only fires in 3 round bursts, so it's not continuous. The fastest full auto SMG types are the Anarchy, Tsunami, Hellfire and Stinger. About the artifacts- that is a matter of personal opinion, personally I think that using explosive artifact with an SMG is effective due to the immediate damage-per-shot that results. Hope this helps!
