OP, that trigger doesn't look right in your pictures. The rearmost part that extends under the safety appears to be half missing. Pull the trigger assembly and post some pictures. My bet is that you got a bad trigger from the factory.

Yes... All of the 0.170 triggers were manufactured like that. They were originally designed to be used in conjunction with the infamous Colt sear block which prevented a full auto trigger from being used. Even after sear blocks were discontinued, Colt continued to used the trigger because there was no need to change it to work with a lower receiver that didn't have a sear block.
Shows what I know. I haven't messed with a .169 FCG in so long I completely lost sight of the neutered trigger.

I think Sweeney talks about all the Colt FCG differences in his book.
Thank you all for your help! It seems it was a very simple issue that was very easy to miss...
Apparently there was a tiny burr in the channel housing the safety retaining pin spring that was rubbing up against the spring. A small file and five minutes and everything works just fine now. With and without the kns pins!
