I shoot my 1100 about the same as your recent 1187 shooting routine you speak about. I take the barrel off, wipe the gas tube clean with an oily rag, and run a bore snake through the barrel after the shooting session. About once a month or so, I spray some clp in the barrel and let it sit overnight or at least a couple of hours. The CLP turns loose the plastic residue that has been stuck on the inside of the barrel and allows for easy cleaning with a bore snake or a brush. I clean the rest of the gun on about a monthly basis in a little more depth than just the wipe down after shooting. Seems to work so far! That routine may be extreme to some and not enough for others. I live in Tennessee. The high humidity here dictates diligence to keep it wiped down from sweaty hand prints and such especially in the summertime.
My son uses an O/U gun for his clay shooting. Pretty much the same goes for his rountine. He runs a bore snake down the barrels and wipes the outside down with an oily rag after each shooting session. About once a month he cleans all of his gun with a little closer attention.
I am sure you will hear more opinons here than you can count. Do what feels right to you and have fun!
