I followed the Burwell trigger work for my 1.0.

Seems the 2.0 has a different mechanism to pivot the sear, making the work on the 'front' tab of the sear obsolete (different interaction from trigger bar)... Only the shaping/height changes to the rear, catch, side of the sear. I did like the ability to adjust the overtravel with the previous job on the 1.0, and don't see how that is obtained on the 2.0. Any 2.0 owners shed some light? I am planning to do the normal buffing internally, but looks like a fairly substantial change on the 2.0 sear interaction.
 
I installed an Apex .45 sear, their competition sear, and trigger springs, rounded the button,and did a little buffing.
I didn't measure it, with a gauge yet, but, I believe it's a tad heavier than my 1.0s, that came in about 36 ounces.
2.0 NEEDS hotter loads to function than 1.0s. I believe it's because of the longer frame rails.
 
I ran my 130pf loads through without problem. I am guessing someone (apex) will make a redesigned trigger bar geometry. The only way to change the break and reset points internally as was done prior with a job in the sear. I think I will still go apex in the 2.0 just for the reshaped face that contacts the striker.
 
On my 5” 2.0, 131pf loads will barely eject, and if I try a full magazine, it will choke. I need to have at least 135pf to run reliably with a full magazine, but, It’s only got 2-300 rounds through it.
Hopefully, it will loosen up, so I can run a tad lighter loads.

Interesting. I am re-working my load up. This was the ~130 for my G34. I have not gotten it on a CHRONO yet. But yes. They barely dribbled out. I run 130grain powder coated TC with 3.8 TG. CHRONO last summer out of the Glock at 1091
 
I'm thinking it will take a couple thousand rounds to loosen it up.
Even with the 13# recoil spring, it's kind of tough to pull the slide back.
