Since you are talking about a 1911 type pistol, I'll chime in.
Adjusting pull on the 1911 pistol is relatively easy...IF you go in with a good idea of what is involved.
The first thing you should do is to buy and study well the book by Jerry Kuhnhausen--the Shop Manual for the .45 Auto. This will give you a good idea of what you're getting into.
For a smooth, reliable pull, there are a number of things you must do BEFORE you even touch engagement surfaces. You must measure the parts involved to ensure that there is enough metal present for what you're going to do. Look at the parts involved--are they MiM or solid steel? Both can be of good quality--I prefer solid steel, but you will be the final judge of that.
You must perform measurements on the frame/receiver. Are the holes properly located and in spec? Is the inside of the frame/receiver clean, smooth, and free of burrs that might interfere with a smooth pull? Is the trigger raceway smooth and even throughout? Even the mainspring housing--is the spring recess clean and smooth?
There are measurements to do to the parts themselves. Is the replacement sear long enough for a good trigger job? Are the hammer hooks long enough for proper tuning? Will the mated parts prevent hammer bounce and sear damage when fitted? How about that disconnector--is it finished well, and is the hole for the disconnector smooth with a good internal finish?
You must also learn the depth of heat treatment of several parts. Something else you HAVE to have down before you start cutting into engagement surfaces--what a primary and secondary angle is on the sear itself. How does "breakaway" work, and what does it involve? If you don't do it right, you (at best) will have a trigger job that won't last 100 rounds, because all of the hardened surfaces will be removed. At worst, you will have a 1911 that goes full auto--and I'll tell you from experience, a 1911 pistol ripping out 8 rounds of full power ball ammunition is no joke--it can actually be a life-threatening experience.
It is good that you have questions about the procedures necessary. Please ask--there are folks here who have experience building and tuning the 1911 pistol who will be more than happy to help. I'll leave you with three reminders for the fledgling gunsmith:
1. Drop in parts usually AREN'T.
2. Measure two/three/four times--cut once and CUT SLOWLY.
3. ALWAYS work/cut the CHEAPEST part FIRST.
And finally....
95% of the problems encountered by shooters can be fixed with a proper detailed cleaning and lubrication.
Best of luck to you!
