take it to a good smith well versed in 1911's & save yourself some headache, worry & quite possibly danger/peril..........this ain't one of the jobs amateurs should attempt in my veryhumble opinion..........it shouldn't cost that much for a good trigger job..........might get him to slick up the feed ramp while he's at it too.Bill at CYlinder & Slide in Nebrask is superbe, his rates are reasonable & he always had a good turn around time too.......
be safe, enjoy life, journey well
