I want to install a Commander hammer in my Colt Sistema 1927. I tried a Chip McCormick for Colt Series 70 but did not worked. Which one I can get that will work as a drop in without modificatins or fitting? Thank you.
You will must either bob the hammer so the rowel does not impact the top of the grip safety, or install a Commander model grip safety, or machine a clearance area into the top of the Government model grip safety.
