$300 seems to be the top end for mint condition

A newish 1300 with all three factory supplied choke tubes is worth about 325$, the OP's best bet if he wishes to sell is to sell the shotgun with the full choke barrell for whatever he can get then sell the slug barrell for 125$ or so.I will go out on a limb and say that the barrell would probably sell much faster than the gun.
