That may have been the case fifteen or even ten years ago, but i have been hearing more and more problems and complaints about new 870's, and now i wouldn’t touch one with a barge pole.
Old 870's are great, and a second hand wingmaster should and does hold the title (IMO) of the greatest shotgun that there ever was, but Remington have really let everyone down when it comes to newer 870 express shotguns.
Just look around on this forum alone;
Poor coating,
Susceptible to rust,
poor ejection,
bad finish (exterior)
bad finish (inner workings)
thats on this forum alone!
Not for me...
I do hear that there are good batches and bad batches though, and i hope you get success with yours.
If they are good, they are very very good; but if they are bad they are terrible!
