One thing to consider too is that sliding a guy handcuffs is a bad idea in that you have now armed him again. What's this? Handcuffs a weapon you say? Highly unlikely?
That's what I thought too until I saw one of our trainers swing a set of chained cuffs and they went right through drywall like it was nothing, tearing a rather large hole. Remeber that that could be your head. George Hill's comments are correct in that if you are going to cuff, you need to do it yourself. It is dangerous to do so without someone covering you, but it can be done.
