Ken 158 were your lightweight cuffs made with magnesium? I had an old salty Sgt that carried a lightweight set of cuffs off duty. Always wanted to grab a set just out of nostalgia. I always preferred Peerless cuffs myself but no doubt the S&W’s are/were quite popular. I liked the way peerless double locked. You could just use an ink pen to punch the double lock. Sorry for the thread drift.
