SA 1911 trigger help

[pepperbelly]

I have a Springfield Armory Loaded .45acp that I use in competition- bullseye and falling plates. The trigger is smooth and crisp but a little heavy for match competition.
At one time dad prepped my hammer and sear- he is a good pistolsmith and used a jig and a hard stone to just remove burrs. During that session I said something about the heavy trigger pull and he looked in his goody box and found a Clark competition sear spring. We tried to install it but with the Clark spring we were unable to istall the ambi safety. It installed easily with the stock spring.
Is there something about an ambi safety itself or the SA pistol that could have caused the problem, or do we need to look at that spring?

One can easily get light trigger pulls from stock sear springs.......I don't think there's a need to change it out at all.

Not sure what's causing the problem, a pic with the Clark installed, would help.

have you changed out the ILS 28lb main spring?

Yes, we changed the mainspring with a Wolf spring- I don't remember what weight but less than stock. I also changed the ILS MSH with an arched non-ILS housing.
We never got the Clark installed. I seem to remember that the fingers of the sear spring were bent at the tip- I think. We couldn't figure why the Clark wouldn't allow the ambi-safety pin to go through.
I read somewhere about bending the sear spring slightly to lessen the pull weight. Was that on this site?

Yes, it has been mentioned here.......it's a pretty common thing to do, so could have heard it most anywhere.
