So you're going to try to bluff him into surrendring. (No ammo onboard)
Do we have scrap for the railguns ?
Yes plenty and the scrapyard represents an unlimited free supply if you ever need more.
He has 900 ton cargo vessel, which probably won't be undefended. And maybe the guys he's dealing with have guns to.
Inquire about the cargo vessels cargo, defenses and the local pirates/mafia/black market sector.
The vessel in question is called "the Cresent Dawn"
The majority of cargo aboard was primarily cheap electronic devces (dishwashers, information storage devices that sort of thing) but there is a lot of it and it will be expensive to replace it all.
The target vessel has two defensive turrets, both are tripple barreled six inch repeater cannons.
They're mounted on the top and bottom of the midsection of the ship and have a slow turning speed.
The Cresent Dawn was supposed to pick up a squad of private secruity soldiers to defend from boarders but they were left sitting at port.
The local pirates usualy (but not always) prefer to surprise ships and board them in shuttles and smaller vessels as primarily they make most of their money selling the captured ship rather than the cargo.
Many merchaniaries groups use cargo ships modified to work as small carriers and fly escourt ready to launch fighter wings if and when pirates appear.
Other merchaniary groups use converted mining craft as capital vessels and some pirates have taken to doing this as well.
All black market deals are conducted across a peer to peer encrypted network but no one on the local black market is offering to sell several hundred tons of electronics.
If you take the job the client will supply with the Cresent Dawn's transponder codes and senosor images of it's engine exhaust profile (unquie to each ship and in space takes ages to dissapate).
