mil-spec trigger job with original parts

[ggun]

Hello 1911 People!

I'm getting ready to do a trigger job on my Mil-Spec but want to use the original parts. I've only got 120 rounds on the gun so the parts are practically new, and although I changed the trigger and mainspring housing, I like the look of the spur hammer and was hoping that I could just lighten up the pull with the original parts except for lighter springs (main and sear). I've got all the tools I need (or are "in the mail"), but somewhere I read that I shouldn't expect to get down below 5# with the stock components and I just don't understand that. I'm hoping that is a misstatement since they also neglected to make any adjustment to the sear spring, so I'm thinking that is the hole in their claim.

My impression is that after all the polishing of parts, the sear spring should be able to be adjusted for practically whatever trigger pull is desired. Is this not true? I'm only aiming for between 4# and 4.25#. I did order a new sear spring to adjust so that if need be, I can always put the unmodified original spring back in.

[And I have read through the many posts regarding safety issues on this job, much appreciated.]
