I am not an LEO, but I do have two pairs of S&W cuffs, one hinged and one chain link pair. They both fit in the Bianchi double cuff pouch I bought (no I don't carry them). I've always had a fascination with restraints, and locks, and how they work. They may come in handy if an intruder enters, finds himself on the wrong end of a 12 gauge shotgun, and gives himself up until police arrive (cuff him to the stair railing).
If you have standard cuffs, they should fit in any standard sized cuff pouch you buy.
