I believe most would highly recommend that a Python owner have the book "The Colt Double Action Revolvers: A Shop Manual, Vol. 1" by Jerry Kuhnhausen. It is available from Midway, Brownell's and/or your book source of choice. It details disassembly, cleaning and inspection and repair/replacement. Although you would generally not want or be equipped or experienced enough to do replacement part fitting, disassembly, cleaning and reassembly is not difficult and the replacement procedures make you appreciate why you would want to send it to a qualified repair facility when necessary. If you are not inclined to buy the book and not inclined to remove even the sideplate or cylinder, then you are left with the option of flushing or dunking it in appropriate solvent like GunScrubber and lubing it with a good gun oil and protectant like Breakfree CLP. There are some posts, notably by Dfariswheel, on timing checks and basic lubing and some posts on cleaning, some under Revolvers and some under Coltsmithing. If you don't spot them, I will search. /forums/images/graemlins/cool.gif
