I used to do that all the time with my Colt 1911s when I shot IPSC, but then I was really familiar with them and knew what I was doing, plus I was shooting them a lot. I could have got away with just field stripping, but in those days I was pretty anal when it came to cleaning.
If it's just casual use and you're not really confident you know what you're doing then as other posters have said - Leave it alone. A field strip will get 95 percent of the crud and keep it shooting just fine. Hose out the other more intricate parts with gun oil and light air pressure to blow it out and dry it and you will be just fine.
If you insist on detail stripping it, then at least download off the web an exploded diagram and instructions, take plenty of pictures at various stages of stripping and keep very close track of all parts - particularly small springs. Some people advocate doing your first detail strip in the bathtub (drain plug in) and shower doors closed (small springs and parts have amazing mobility).
There are guns I just refuse to attempt to detail strip because of their complexity and the fact I don't use them very often.
Having the right tools such as properly sized screw drivers, brushes and drift punches helps a lot.
