For regular maintenance of O-Frames, especially carry guns, the extractor and the firing pin should be removed and the tunnels cleaned. For the Kimber Series II and Colt Series 80 with the firing pin safety, this is a little more involved but still doable. You need to depress the firing pin block out of the way so the firing pin and the extractor can come out. The firing pin should come out easily but the extractor may need a little finessing. Try rotating the extractor in the channel until it slips pass the depressed firing pin block.
A .177 cal airgun brush fits the extractor tunnel. A q-tip can be used to get power solvent in the tunnels and swab out residue. Can air is good for blasting out any remaining crud.
Make sure the extractor hook is cleaned of any debris. A bronze brush works well to clean off any caked on power residue.
Don't forget the firing pin block. You can't remove this without taking off the rear sight so it must be cleaned in place. Any of the aerosol cleaners will work. Follow up with can air to blow out the remaining cleaner.
After you installed the extractor and FP into the slide, do a check of the extractor tension to detect any gross changes. You do this by slipping a fired case under the extractor and feel for the amount of force the extractor is exerting on the case. The amount of tension the extractor exerts on the case can vary significantly between guns. So, know what you gun is like and watch for any sudden changes.
Another thing I forget to mention on the tool list is the needle oilers.
NEEDLE OILER BOTTLES at Brownells
I like these because of the precision and reach I have with the needle.
For the tupperware shooters, You can't neglect maintenance either. If you have a lot of rounds through your gun, consider replacing all the springs in the gun as a preventive measure. They are fairly cheap and from what I've been told, pretty easy to do. Also pull the extractor on a regular bases and give the hook and extractor cavity a good cleaning. Again, it's an easy thing to do and there is no need to prove Glock reliability with your life.
