I've always been a fan of Hiatt cuffs because of their locking system. I got these and haven't been disappointed!
I have a pair of ASP ultra hinged 3 pawl, a pair of peerless 802 hinged handcuff, 2 pairs of S&W model 100's and the Hiatt hinged cuffs. These are by far the most solid hinged cuffs of all of mine and cost less than the ASPs. If you are debating which hinge cuffs to get these are by far my favorite.
