Here's the pair of HD/SD shotguns that I've put together over the last couple years. The M500 is pretty much stock, except for the VR barrel cut down to 18.5 inches. The 870 has a SF PG stock, factory extension and GR sights. I think that I might swap the GRS for a dot sometime soon. These are both great shooters and I can break 8/10 hand thrown pigeons with them.
