Exciting, I want to see pics! My Google-fu struck out.
it is already in progress .
it probably was one of my TSO

The pic offered by @GunBugBitdoes not do the EE Race Disconnector justice............
The contact surfaces come pre-polished:
i use EE parts and like them. but it's not 100% drop in set for my requirements. it needs some work for 100%
and after this it works perfect and long time.

This picture shows what’s unique about these disconnectors.
This disco urgently needs polishing.
Which company's part? It doesn't look like casting. The part looks good quality. but unfinished.
Because of all these problems, 6 years ago I managed to perfect the trigger system of the 1911 and it works for me in both guns with the trigger weight of 550 grams in one and 650 in the other without change.

From what you have described it sounds like more of a High Primer situation than anything. If the Primers are flush or protruding above the brass at all they are not seated deep enough. When the primers are seated to the proper depth they should be recessed a little bit vs the top of the brass.
High primers can also cause the slide to not fully lock up in the full forward position because the extractor hook depth is fighting against the brass rim because the primer is pinching against the breach face instead of the bottom of the brass. If the slide is unlocked even a little bit the hammer will fall against the bottom edge of the firing pin stop instead of the firing pin.
I came across something like this. I checked Headspace and saw that chamber was too tight. The problem was fixed and never reappeared.

So if it works 50/50, at least they should have given you a 50% discount.

Learn how to stone the sear, hammer and tune the sear spring tension.
Luckily I no longer need to tune this spring.

TGO runs very light triggers FWIW. He was annoyed when at a long-ago IPSC equipment-check the RO dropped the slide by accident, possibly beating up the hammer-sear a microscopic amount.
TGO ???
if u mean TSO their trigger system different from 1911 .
Power transfer ratio for the trigger pull in TSO around 1 to 4 and in 1911 1 to 1

It sub 2 lbs triggers are lasting 80k rounds without adjusting the spring, I'm not to worried about it either way. Generally I don't go under 2 anyway.
I've handled sub 1 lbs triggers, but I really don't see the point in that.
It also depends on the work on sear /hammer hooks for trigger job . Some guns will hold it and some will not.

That didn't really answer his question though. Why would a spring under less tension not last as long as one with more?
I find it hard to imagine the sear spring really wearing out when it's barely doing anything on a light trigger.
When a leaf spring is calibrated to a small force, there will be less pressure on the sear and it will not be able to respond as quickly as a spring, which operates at full force. Therefore, it is expected that the gun will fire bursts or hammer falls.
These springs have almost no wear . Just fatigue of the material over time. Just fold it back a little and everything returns as it was.

So why would going lighter stress the spring more? If it'll run 80K rounds at 2 lbs, its exerting more force and doing more work than it would when set to 1.5 (probably closer to where my triggers are) or even 1 lb, right?
I tried to shoot in 2011 with a trigger pull of a little more than 1 pound and it didn't suit me because I didn't feel the trigger. That's why I found that for me the best trigger for 2011 is between 1.5 and 1.25. On the other hand, in CZ I work with the trigger of 480 grams and it is comfortable for me.

Under 2lb somewhere. I care more about the feel of them than actual weight so I rarely bother to weigh them.
Springs not heavily loaded can run a very long time before fatiguing. A bit of quick estimation-math says the valve springs in my truck are around 20 million cycles each and are doing fine...
With a leaf spring set to trigger around 2 pounds there are no problems with leaf spring response and there should be no hammer fall.

Just a Colt sear spring and never tweaked.
In the experiment I used springs without a manufacturer's name and after 50k cycles the change was a reduction from 1.75 pounds to less than 1.25 and there were hammer fall after that
That's why I changed the trigger system in my gun so as not to depend on a leaf spring. The trigger on the gun was set to 630 grams and over the course of 4 years it dropped to 550 grams with no hammer fall in rapid fire.

I've got at least 80K each on two Dawson open guns with the original 3-finger leaf springs. YMMV.
What is your trigger weight?
I built a device to test the force drop for a leaf spring. There is a direct relationship between the amount of cycles it makes and the fall that makes it unsafe. And will cause the hammer to fall or double fire during rapid fire.

There is a theory that this lets air in so any smoldering ember will burn quick and go out. The counter is leaving the hammer down will suffocate a burning ember.
And I thought it was because of the moon's gravity.

1911.com has a wealth of info on 1911 trigger jobs, that site has some of the most knowledgeable smiths on it. My MCG open gun has 80,000 rounds with no follow with a one pound trigger with all original parts. You should never get hammer follow with any trigger manipulation.
If you use a 3-finger leaf spring, then I find it hard to believe that it saves 80k on a 1-pound trigger job, because one of the properties of a leaf spring is fatigue and power loss . Unless you use a different trigger system or strengthen the spring force from time to time.

I see you also built a scope mount
Similar to mine. Only in mine there are no sharp corners.
nice gun

Weird stuff breaks on Open guns. I had the thumb pad of a thumb safety snap off once (just the pad, the rest of safety was fine). And it was on the side I never use. Dawson looked at it and said "Open guns [break odd] things sometimes".
You have a smart gun it has disabled that pad because you don't use it

Lighter slide = less reciprocating mass.
Less mass = less spring force needed to slow/stop the rearward moving slide in recoil.
Less mass = less spring force needed to close the forward moving slide.
The whole theory is only about forward direction. Just forgot to mention that with a small mass and a weak spring there is a chance to get the broken slide in the face due to strong recoil.
Don't forget to include in this theory also the negligible thing called impact. MV/T.

Everything I’ve read is the opposite: the lighter the slide, the lighter the recoil spring (in general).
In which book did you read such things?

I would not want to destroy a good mag. instead I would grind the IPSC mag Gauge .

work looks great on this 5.7".
I have one 5.3" and another 5.1"

Looks great. I see that this is a model that is manufactured in the USA and not in Europe. So I understand that it is made of metal, which is intended for firearms .
