Personally, I wouldn't cut down the original stock if you will ever sell the gun. You can get a stock on Ebay that somebody has taken off to turn their Mossberg into a mall ninja weapon. Wait until the right one comes along (maybe one a little dinged up and is lower priced), cut it down, and put on a grind-to-fit recoil pad. Cutting and grinding is something an average guy can do. That way, you can always put the original stock back on if you want to sell it.
