Heavy long trigger pull, you are actually cocking/loading, and firing the gun with every trigger pull. (I can't remember if that means double action or single action).
Depending on how hard and fast you pull the trigger you can get more velocity too! (Slow pulls shoot soft, I don't think it will ever shoot "Hot")
LOVE the magazine/loader system though! Fun little guns, can still hold their own in more urban or close quarters games no problem!
