One problem I have 1 issue with 870 20 ga. Guns. It's the laminated stock. Keep that gun from getting wet. The stock will swell with water. I took it on a hunting trip, and after I shot my first buck (on a day where it rained from 330 am to 1pm) the next morning my cousin used the gun. Couldn't load or cycle shells because the stock and forearm swelled about 1/4 inch.
