I mean they are good build quality typically, but they have no shim protection, 1 pawl so easy to pick, not only that but the key position/angle makes picking even easier. Peerless would be slightly better in terms of picking. Why don't police choose a better cuff that people cannot shim or easily pick? They exist, they are not prohibitively expensive either. True NIJ certified cuffs. They wouldn't need to pay a million bucks for the best of the best of the best or anything but about anything would be better than Smith and Wesson. Wouldn't you agree?
It's simple economics- buy several hundred duty pistols like the M&P, AND agree to have S&W send boxes of handcuffs over the course of several years for your department and get a discount. The S&W cuffs seem to work fine for duty use, and I've never seen anyone shim them. Offenders either try to slip them off or try to get their cuffs up front, that's about it. What I don't like about the S&W's is that since about 1997 they have lengthened the links by about 1/4" making the key way stick out the side of the black box, making it possible to use a standard key to open them even with the handcuff cover in use. I emailed S&W telling them about this, but they never responded and the cuffs are still made with the longer links, which is why Peerless cuffs with the key way in the center are better when using the black/blue box. Just my opinion after 15 years on the job moving prisoners.
