Remington 870- an older one. Or save a few more bills and spring for a Benelli M2 Tactical.
I, too, like the Mossberg 500 for the "tang" safety (there really is no tang) but with one caveat.
The safety button is plastic and often breaks. Metal replacements are inexpensive and easy to install, and I strongly recommend doing so before putting the gun into service.
Who's the owner du jour?
I actually have an S&W 3000 which is the precursor of the 870 so it got my vote.
I didn't know that. I figured the 870 had been around far longer than the S&W.
