Just installed the sear on my standard Shield 9 and have a PC to compare.
PC9 at 200 rounds at 5# 15.1oz
Shield 9 before (485 rounds, decent dry fire): 6# 10.4oz.
Shield 9 after Apex Sear 100-063: 5# 3.2oz. (dropped 1# 7.2oz)
While I was in there, I messed with the trigger bar: 0.021" stock, widened it to 0.028" then closed it to 0.016" but over-travel was still at 2-3mm (used a punch behind the notch on the trigger), similar to the PC's overtravel.
I'm going to double check my values later on but the PC has the longest take up and the least sear movement. 5mm reset in the Apex'd Shield vs 4.75mm in the PC.

I tried an Apex 063 and it was very nice but too light for carry from just under 4lbs to just over.

The heavier spring is the one under the cap that is under the sear right? I may have to look for a stock non performance center spring to try in my PC9.
