i visited my local pawnshop today and spotted a mil spec mossberg 590 police trade-in. Except for the finish, the shotgun is in perfect working order. It comes with speed feed pistol stock, and all for $250. My first question would be if this is a good deal or should i pass. I seem to keep comming back to this shotgun, but due to lack of income i am unable to make the purchase. However I have a winchester 1300 defender that I would be willing to trade for it. My second question is should i go ahead and trade for the 590 or should i keep the winchester. thx
