Hi, I just bought a Rem 870 express with a 2 shot extention from the factory. Model number 5077. Note this gun is not on the Remington web site, and this is an express model not the police. The reason I am letting you know about this is my dealer told me he is getting them for the same price as the standard 870 HD, and you might save some time and money if you order this model to start with. There are no dimples on mine, however there is the dumb safety lock on it. My dealer is pretty honest with me, he told me his cost is $235, same as all the base model 870s. Hope this helps someone looking into the 870 as a HD weapon.
