There is such a thing as too much oil. Oil attracts dirt and dust, so keep it out of the trigger group and firing pin channel.
I use Breakfree CLP for quick cleanings...
>Brush bore
>Spray CLP in bore, and let sit
>Brush slide, frame, and trigger group
>Run patches through bore until clean
>Put a drop of CLP on each rail, and one drop on the top of the barrel
>Rack slide several time
>Put CLP on a rag/a few drops on the slide, and wipe it down
My .45 Compact has had about 1700 rounds following that regime, and is working great. Every 500, I'll detail clean the inside of the trigger group and innards of the slide using Hoppe's #9 solvent, and a mountain of Q-Tips. Just know that you'll hate shooting such a clean gun after that.
