I clean any gun any time I shoot it. Not a complete detail strip, but a quick spray and wipe. 5 minutes at the most, usually less. Even stainless revolvers. I like an 1100 because I can hit what I am shooting at with one better than anything else I have shot in 54 years, except a Wingmaster, and that's a tie. Over 40 other shotguns have come and gone at my house in that period, and I shot I don't know how many others, so it is not like I haven't tried about everything there is. They do run a little dirtier than some newer designs, but not so dirty I have ever had one stop running on me, even with filthy heavy Blue Dot reloads. I don't really want to know how long it could go between cleanings.
I will never go to Argentina and shoot 300 doves, much less 3,000. Just not my cup of tea. If you like it, more power to you. I know they are so numerous you can't put a dent in them, and they are agricultural pests, etc., etc. Sounds a little like what they said about the Passenger Pigeon, before we wiped out what was likely the most numerous warm blooded species the planet has ever seen. I am not saying YOU are the problem, but given the chance we people seem to be able to screw up just about anything.
I have run over 115,000 rounds through one of my 1100s with one broken extractor to show for it 34 years ago. I did not shoot them all in the same weekend. Only part I have ever broken on any of them.
