870.I've had both a defender and an 870.I beat my shotguns around and am hard on them.The defender lost every bit of bluing/finish from the forearm after 1 week of use,I purchased it new.I dont know if it was me racking it too hard,too fast or the fit of the forearm vs the mag tube dimensions.I sold it for 125 bucks after 2 weeks of use.
The 870, my old standby, is an express magnum with a choate 8 shot extension on it for HD.its been many years and all the finish is still there except on the bolt, which has lost most of it.Im considering swapping out the bolt and trigger gr/mag latch for one out of an old police gun that is chromed for slicker action.Its taken many cottontails,varmits, and a few coyotes that were getting too close.I have a trap barrel for it and though I dont win much, it does well against my friends winchester semiauto at the bird stations,his remy 1100 is broken with yet another gas ring problem.I like its dual purpose, one thing a defender didnt have.
