I just finished with my 1st trigger job. It was about 3 weeks in the making so it was nothing I just jumped into. I gathered all the info I could wrap my brain around and proceeded to get all the tools, equipment, and even hung a gun tool cabinet in my man-cave/reloading/amature gunsmithing corner of the house. I hit a few bumps along the way. Some I was prepared for, others not-so-much.
I started out installing a new trigger, hammer, and beaver-tail grip safety. After doing so, I went to the range with 150 handloads. I had about 10% light primer strikes with a 5lb trigger pull. The new hammer was quite a bit lighter than the stock hammer; http://3.bp.blogspot.com/-VQXWENMLbU...%2BLog%2B1.JPG
I read that most stock 1911's have a 23lb hammer spring. I ordered a full range of hammer springs from Wolff ranging from 16lbs up to 30 lbs. I decided on a 25lb spring. The old spring was much shorter and weaker after only 1100 rounds. I installed the 25lb hammer spring and now I have a 7lb trigger pull. (not what I was after at all). In the mean time, I had ordered a Marvel Sear Jig from Brownell's still waiting to be tested. No instructions came with the jig, so I dug up as much info on the Internet as I could after emailing them for the instructions with no answer.
After getting my ceramic stones and a jeweler's lighted magnifying glass from Amazon, I began the journey of stoning the sear and hammer. I worked on it a few hours-a-day. The trigger was down to 6lbs with very little creep. (nice and crisp) Still not happy with the results, I continued working on the sear and hammer a little at a time. I was disassembling and reassembling this pistol at least a dozen times and the 80 series block safety crap was getting on my nerves! So I ditched them!
After getting rid of the 80 series safety stuff, I went for the lightest trigger pull. I adjusted the sear spring, disconnector spring, took the hammer feet to .020 and further stoned the sear with the super-fine stone and brought it to a mirror polish. I was hoping for a 4 1/2 - 4lb pull, but 3LBS on the nose???????????? HOLY CRAP!
I'll be taking it to the range in the next couple of days with only 2 rounds in the mag then progressing to a full 8 round mag in case this thing goes full auto on me. It will be easy to get to the 4lb pull from here by simply adjusting the sear and disconnector springs back to original.....but talk about a SWEET TRIGGER PULL with a crisp 25lb snap!!
THE TRIGGER GODS WERE WITH ME TONIGHT!
