Poor fit.

The product itself is great, it's very sturdy, design is good, machining is good, but on an 870 Police with a Vang Comp magazine extension the clamp caused a measured .025" deflection of the magazine tube because of the center contact surface/where the Allen head screws interface. The clamp requires extensive modification to fit the contours of the barrel and magazine extension without causing deflection. I suppose it's entirely possible that my police trade in 870P has a non standard spacing, but I rather doubt that is the case considering the amount of material I had to remove from the clamp before it would attach without spreading the barrel and magazine extension. Again, quality product, but I cannot give it more than 3 stars considering the level of modification necessary for it to work CORRECTLY on MY shotgun. As always, your mileage will vary.

Good clamp but has some flaws

It is a good clamp but I personally had some not so great things happen with it. For one it absolutley ruined the finish on my barrel and mag( I didnt mind too much since it is a combat shotgun) but the thing that really bothered me was the screw stripped out after shooting it one time with a TLR 1 light on it.
