Yes polishing will help to a degree if done right.If done wrong you can have a dangerous gun in your hand.If you need trigger work because the pull is attrocious,don't dig in there if you don't know what exactly to do,let a smith do it until you learn.I think 1911.org and the Sight have articles along with many Smiths.I put an explanation on Pvt.Ryan's forum,but there is alot of basic and related info not included to keep it somewhat short.While it doesn't explain any functioning of parts,you might pick up some info from it.There are pics of areas to polish for different parts.
