longer sear?

after much messing about with following and some doubling :(
ive come to the conclusion that my frame wants a longer sear than the ground down ones i have.
i whipped up a little drawing for your viewing pleasure

i know that im on the steep learning curve on this
and realize that i pooched up the Wilson sear i tried to setup (and the hammer as well)
but looking at the pin hole locations, i can see that im already in trouble if im starting with a sear thats even as long as .455". any work done is going to drive it short very quick.
am i barking up the right tree here?
would a longer sear keep me from getting in trouble so easy
 
I am not sure what you are trying to do. Do you want a long sear just so you can have fun filing it down? The 1911 sear length is pretty well set by the combination of frame, hammer, and trigger bow, and any sear you buy has to be within the specs or it won't work. Usually sear work involves smoothing or reshaping the sear surface slightly IF NECESSARY. It does not involve hogging off metal.

If you did have a greatly oversize sear to cut down, you would also have to have the means of hardening it, otherwise it would wear out very quickly.

i want to find a sear that i can experiment with and hopfully end up with one that works, much unlike i have now.
after much reading it seemed like i had gotten in trouble because i have a frame that makes a sear appear shorter than it is.
so if i start with a sear thats .455" from the outside of the pin to the nose, i dont have alot of room to experiment with before i get a sear that follows,doubles and misses the thumb safety
 
I think you need to get Jerry Kuhnhausen's two books on the M1911 before going any further. Trying to improve the trigger pull is a reasonable goal, but blind experimentation can get pretty expensive (and frustrating).

Well, Kuhnhausen's Shop Manual clearly shows the proper shape of the sear and hammer notch, plus drawings of the parts with dimensions. And to work on sears, it is a good idea (like essential) to have a good sear jig if you want to do a quality job.

AFAIK, there is nowhere you can buy a sear as much oversize as you seem to want. I guess one could be made if you have the tooling and the machinery.
