Peerless, S&W, Safariland (Who now make Hyatt cuffs here in the States). These 3 are good. However, I have never like S&W's side lock slot. Too hard to hit when a Perp is un-co-op. I carry Hyatts lite cuffs, because as I get older, I like the weight off my belt. If you want steel cuffs, get Peerless. S&W build a better hinge, IMHO however. I think S&W has gone back to the pin lock in the frame in one of their cuff models. Check them out. Good place for cuffs is Handcuff Warehouse online. They have cuffs you have never even heard of.
A quick side note: Buy quality cuffs from the names I mentioned. Inexpensive cuffs from LE catalog companies will get you hurt, the cuffs are usually of poor materials and construction.
And the ASP plastic cuffs? Not junk at all, well made. But way to much flex in the single and double strand, they can cause problems during speed cuffing, as the single strand can miss the double strand entrance slot, IMHO.
