I will be getting a SP5K and Dakota Tactical full size Mp5 SBR in the near future when available. My only question is I'm left handed and have never fired a MP5. I like that the SP5K comes with ambi selector. The mag release will be a non issue but how much of a pain is the cocking handle to manipulate left handed? I would think just rotate up and use right hand? Just seeing how others do it. I've always wanted one of these (or three) and now it's time to make it come true
