OK y'all, here's what I got. First a few notes:
-FCU#1 was tested after 1000 rounds through it. FCU#2 after 100 rounds. I found a 7.6oz reduction in #1 after a 1000 just from break in. (7#9oz to 7#1.4oz)
-FCU#2 was almost 1lb lighter than #1 outta the box. Wonder what the variability range from SIG would be if you checked a hundred of them?
-All measurements are an average of six pulls on a Lyman gauge (pretty cheap on Amazon, BTW) at mid trigger, the same way Bruce Gray demonstrates in his video. If you pull the trigger closer to the tip (as I do when shooting) the extra leverage decreases the pull weight. (by more than 1/2 lb in some cases)
-The GG measurements are with the included GG spring.
-Despite claims that the Apex 1.0 gives no pull reduction compared with standard, I found a modest reduction in both guns tested.
-I had a challenge installing the Apex 2.0 in BOTH guns. The problem was the engagement of the trigger pin into the trigger bar. Took me 5-10 minutes to get it to settle in each time. Once it was in though, it functioned just fine. All the other triggers I can do in less than a minute without tools. (GG method again) I have done dozens of changes in those other three triggers and it's a breeze. Not the 2.0, at least for me. Maybe I got a bad one...
-The second number I give for each trigger is the reduction from standard. Please forgive me if the math is screwed up!
-As mentioned before, I plan to repeat these for FCU#3 sometime soon.

Now the data:

FCU#1
Standard trigger: 7#1.4oz / --
Apex 1.0: 6#9.6oz / 7.8oz
Apex 2.0: 5#10.8oz / 1#6.6oz
GG: 4#4.9oz / 2#12.5oz

FCU#2
Standard trigger: 6#12.2oz / --
Apex 1.0: 5#12.1oz / 1#0.1oz
Apex 2.0: 5#1.5oz / 1#10.7oz
GG: 4#4.2oz / 2#8.0oz

Hope you find this helpful.

Cool Brian. Does he happen to work at Point Blank Range part time by chance?

P.S. to my data: All my aftermarkets are flat triggers.

Not terribly sure. I'd have to ask.

Reason I asked: I recently sold a S&W Shield to a Centerville PO who works part time there. Blanking on his name.

I don't think he does but it's possible. His name is Nick, bigger guy and bald.

If you could I'd like to know the weight using the apex 2.0 with the GG trigger bar spring
Thanks

Thanks for taking the time to do this. There seems to be not much of a difference between the two Apex triggers if you start with a good stock trigger. Since they are the same price I would purchase the Advanced. A friend has an Apex 1 never installed that he will sell cheaply, I might just go with that one though.

OK, I will do that too. I did previously try the Apex 1.0 with the GG spring and found it to be about a quarter to halfway better between GG trigger/GG spring and Apex 1.0/standard spring.

I think the Apex 1.0 is a nice upgrade from standard, especially if you are looking to change from curved to flat for low $. For me, that was a great move because I get a significant bite from the curved. (but that's just my deformed hand) Pull weight is one thing, but feel is another and I think the latter is more important, at least for me. The pull weights are a factor, but probably splitting hairs compared with feel.

Don't think it the same guy.

What the heck, for sake of completeness, I will check the GG spring with all of the non-GG triggers on all 3 FCUs. Just give me a few days...

Just finished tests with FCU#3. It's getting late so I will post the numbers tomorrow, hopefully. Preview: the results are very consistent with those for the first two FCUs.

Apex 2.0: 5#1.5oz / 1#10.7oz
GG: 4#4.2oz / 2#8.0oz

Hope you find this helpful.
Here's what I found for FCU#3
-#3 was tested brand new out of the box, never fired. I took it apart, cleaned it and relubed the trigger bar and trigger contact points with Lucas grease per GrayGun video.
-Forgot to mention before- all three FCUs and triggers were tested with the same 9mm compact grip and slide assembly.
-Installing Apex 2.0 on FCU#3 was easier than installing on the other two. But still not as quick and easy as the standard, Apex 1.0 or the GG.

FCU#3
Standard trigger: 7#7.4oz / --
Apex 1.0: 6#11.3oz / 0#12.1oz
Apex 2.0: 5#13.9oz / 1#9.5oz
GG with GG spring: 4#6.0oz / 3#1.4oz

When I get a chance to do some more calculations, I will post average figures combining all three FCUs for a more composite look at things.

I also plan to try the GG spring with the non-GG triggers to see what effect that might have.

OK, so here are my final numbers averaging six trigger pulls on a Lyman of the four different triggers on each of the 3 FCUs (given above) and then averaged again between the three FCUs to give one overall average pull for each trigger. If it sounds complicated, it was, but kinda fun.
-Listed as overall average pull / Reduction from standard trigger pull

Average for 3 FCUs:
Standard trigger: 7#1.6oz / --
Apex 1.0: 6#5.6oz / 0#12.0oz
Apex 2.0: 5#8.8oz / 1#8.8oz
GG with GG spring: 4#5.0oz / 2#12.6oz
