I use Amsoil on my Kimbers and ARs for lube , had a quart of 20-50 left over and decided to try it and it is the slickest, smoothest stuff I have ever used on a gun and the heat won't burn it off.... not to mention a quart goes a long way.
I use Hoppies on the inside of the slide and frame.... and foaming bore cleaner and a boresnake on the barrel on my handguns.
Fill the barrel with the foam (put your finger over one end or it will go everywhere) set it aside and clean rest of gun so as to let the foam do its work.
When you are finished with the rest run the boresnake through it, wipe down the outside of barrel and give it a light lube on the outside including the locking lugs and the barrel hood....just a couple of drops will do it.
As far as the slide goes I put some lube on the rail recesses from the back with the slide standing on it's muzzle and just let gravity work LOL
IMO any more lube than that is just asking for dirt build up.
Also take off the grips ever once in a while and clean under them and to check for rust......and yes even stainless guns rust.
I have rusted every Stainless pistol I have had from carrying it...between the sweat/humidity and the grips trapping both they rust.
If the barrel on your Kimber starts to rust or discolor some (and I say it will given time) , I just use 800grip emery cloth or Lead Away cloth on mine and lube it again....... it just seems to be a Kimber thing every Kimber I has seen will or/has done it , stainless barrel or not.
The ARs get Hoppies all around, using wet patch and boresnake on barrel, along with a scrubbing and scraping of the BCG.
Tried the foaming bore cleaner on the AR once LOL.....never thought I was gonna get it out of the gas system
Ok I will stop babbling now.........
