I just picked up my new Christmas present from my wife. It is a police trade M1 Super 90. I am completely new to the Benelli game and need info. I did a google search and did not find a lot useful. This gun is an older model, with Heckler and Koch (Sterling Va) stamp on the right side of the receiver. It has cruiser rack finish wear on it but is practically new inside. I would like info on disassembly for cleaning and what to look for in normal or abnormal wear. I figured for $499 out the door I could probably do worse on a deal. It has the extended tube and ghost ring sights, so all I figure I need is a Surefire fore end for it and it will be as pimped as I will ever need. Any info on this gun as far as manuals or tips/tricks to keep it running smooth is definately appreciated.
