He ya'll.Could someone explain to me exactly how a good trigger job is done?I am aware that stoning the hammer and sear is a critical part of the process in getting the right angles.But how exactly does tweaking(or whatever the term is) the sear spring and mainspring work?How does this work in deternming the poundage of the breakage point of the trigger?Do all the three tangs/prongs of a sear spring come into play in defining the triggers action?Or is it just one tang that is the key?Does a trigger itself,such as a Videcki,need to be fitted to the frame?Does the bow need to be modifeid in anyway towards each individual 1911?If any, how much of a role does a disconnector play in a trigger job?With the close tolerances of modern machine work and the help of CAD,CNC and EDM why cant sears hammers and springs be just drop in parts?Do the tolerances of the holes in the frame vary from frame to frame?Thanks.

Well if you can get a good gunsmith to tell you his secrets to a good trigger pull you'd be doing something. The basics you can find in some of the books. I know this much, it is much more complicated than it looks. Drop in kits don't always work because of the difference in hole spacing from one frame to another which affects the sear angle, yada yada yada. IMO you're much better off to leave this work to a pro.

The mainspring exerts force on the hammer strut, therefore the hammer. The higher the mainspring weight, the harder the trigger pull.

The sear spring works as follows (when viewed from the rear of the gun:
The left leaf exerts force on the sear. More force = harder trigger pull.
The centre leaf exerts force on the trigger bow. More force = harder trigger pull.
The right leaf exerts force on the grip safety only, and does not affect trigger pull.

Most drop in triggers need to be fitted on the top and/or bottom of the pad area where contacts the frame. The bow usually needs no fitting.

The disconnector plays only a small role in the trigger pull equation. The centre leaf of the sear spring also exerts force on the bottom of the disconnector. The contact area between the trigger bow, disconnector and sear spring should be polished smooth and lightly lubed.

Check out www.m1911.org for disassembly instructions, where you may get a better feel for how all these parts co-exist.

Thanks Shane45.Your explaination was easy to understand.
