870's in to clean? Really? It takes about 10 seconds to field strip one of those. I shoot with a guy once in a while with a Benelli semi auto, when he takes it apart to clean it he always ends up with short strokes and jamming, has to jam his knife into the action to clear a shell. Maybe it's from working with mechanical things so long but guns are very simple to reassemble.
I have a 930 that I do a quick clean on every time we go through a hundred rounds of trap loads (They're dirty as hell) and never had an issue.
I guess it just depends on how you grew up, on the farm if you couldn't fix it, you had to buy it and that often wasn't an option.
Car owners manuals have to state not to drink the coolant now adays. Pretty much sums up the world we lie in
