I cast my vote with GlockRock. Have used the ASP chain cuffs for several years now. Very nice tool. I won't use anything else. ASP even engraved my name and Dept on them. You can't go wrong with em.
I have owned Hiatts, ASPs, and peerless in the past. I ALWAYS come back to my S&Ws. I carry a M300 hinged, a Model 1 over-sized and a M100. Mostly because Hiatts went out of business.
