Paul - I am really sorry to haer about that bad experience but will welcome you openly to this forum. As Volshooter and the Iowegn have already said, you have a fine new piece and their advice is very sound.
I would add only to purchase lots of ammo and practice a lot with it. My preferance is for Sellier and Bellot 230 gn ball - it is inexpensive, loaded to mil-spec and reloadable. I carry it in my 45s and mil-spec ball has never failed me.
I would add only one more piece of advice to both you and the Volshooter and that is - gentlemen, it ain't the size of the hole in the end of the barrel, it is the man holding it that takes the field, and that's just my two cents worth.
As for maintenance: disassembly of the 1911 is fairly simple and if you do not have disassembly instructions they are very, very easy to come by - Kimber may have some specifics regarding the takedown of thier particular models and you can always request that information from them.
As for me, I usually clean and lubricate my 45s after a range workout of 2-300 rnds, load them up and holster them for future use. There is no real secret to cleaning or maintaining the 1911 pistol, it is fairly easy. I hope this helps, and anytime you have questions please let us try and help. Mikey.
