Can't go wrong.
I own 2 870's. I've tried some other shotguns but I keep selling them and coming back to what's confortable and reliable. My 870's will cycle any shell made, will work with amazing amounts of grit, mud, muck, grass, weeds, dog hair, etc congeled in the action, and they're economical to buy.
My 870 express has killed over a thousand ducks and countless geese, quail, dove, grouse, and turkeys. And it works as well as (actually, better than) the day I purchased it. Now it's my backup gun and I shoot a new 870 super mag. Same story with the new gun: bulletproof. I've fired thousands and thousands of rounds from these 2 guns and I've never been let down.
I've also used my (unloaded) 870 by the stock to dig out my Toyota from the mud, and as an emergency boat paddle. Versitile!
If you're looking for a safe, blue-collar starter gun, look no further.
