The only thing that you do want to keep in mind is that once you SBR the draco, you MUST be in possession of it. I.E. I cannot make one my "trunk gun" even though that is the best use of it because if I let my wife drive the car, then BAM! she is one search away from big time trouble. And forgetting is no defense.
That is the only downside I can see.
