Well I decided to have a go at a trigger job on a 1911. I took the sear and hammer and touched up the engagement surfaces with 400, 800, and 1200 grit sandpaper backed up be a steel straight bar, and then buffed them by hand on a piece of cloth with jewelers rouge. Should finish buffing the rest of the internals and have it back together in a couple days. Trigger pull was about six pounds and kind of gritty feeling, I will post the results. I was too chicken to change the engagement angles so I am not sure how much improvement I will see.
