The 870 Express? I
love my lefty 870 Express! [8D] It does anything, shoots anything, goes anywhere.... It's the best bang for the buck out of any other shotgun. I think it's been said somewhere (indirect quote):
Throughout the years, at one point or another, everyone has owned or borrowed an 870!

P.S. as far as the rusting issue, just keep some of those dessicant(?) little packs
{that stuff that looks like a small pack of sugar} in the gun case, and every so often, wipe it down with a silicone cloth. I *still* don't have one speck of rust on my 870 Express!
