So I finished up the install yesterday.
Some notes about the trigger.
The pre-driven pin that must be driven into the existing trigger bar was a PITA hammer in. I've installed several FSS kits in the past and this Shield Trigger was by far the hardest I've done. I used a 24 Oz dead blow hammer and 1/8 inch punch.
Honing is required around the radius of the hole that sits in the trigger. This is to prevent binding. YMMV.
The trigger guard opening also required a little honing using a fine diamond file, since the left and lateral portions of the frame would bind the trigger. I removed 1/64 inches of material. Barely noticeable, but makes a big difference in fit. Again, YMMV.
The trigger bar loop required a minor adjustment by opening it 1/32 inches. I used feeler guages. Without this adjustment, the trigger bar loop would not engage the sear to release the firing spring. Thus, it would be a dead trigger. This minor adjustment, just like the FSS, concludes with a very nice, crisp click.
There is significant reduction in pretravel. The combination of this trigger with the DCAEK is 1000s times better than the stock trigger assembly. Reset is much more pronounced, too.
Got some range time today. 750 flawless rounds, no issues at all. Zero. (I had to eventually wear gloves since my hands were going raw)
I'm comfortable enough to carry it.
