Will an 870 Police stock fit on an 870 Tactical Express? Is the Police stock more desirable that a normal 870 stock and why? Does it come with the needed hardware to install? Or is that a separate purchase?
Which is more widely preferred, a normal fixed stock or a pistol grip adjustable stock on a tactical shotgun?
Current configuration is Remington 870 Tac Express with Knoxx Stock and XS Ghost ring sights, added +3 tube extension for 7+1, 6 shell side carrier, magpul moe forend with streamlight TLR1s light. Weight, who cares about weight right?

The reason for changing the stock is bad reviews on gen 1 knoxx stock breaking and recoil to the face.
