Russian commercial high capacity (IJ-70-18AH or IJ-70-17AH): $250 - $4000 Note: 12-round magazines add about $75 - $90 each to the value
Yours can take cartridges 25% more powerful then older models/Versions like the type made by powerball and buffalo for self defence. Keep It if you have any problems with the magazine loading or the slide getting to weak to load rounds get new springs from Wolff a main spring recoil slide of about 19lbs will set you up fine. I wouldn't sell it lower then say $350-400 even though I have seen them lower becuase of the economy being bad....keep it pass it on to a grand child.
