Good trigger but... - APEX Action Enhancement Trigger KIT

I like this trigger a lot (hence the 4 stars) but I could not recommend it to a loved one yet. Stranger on the internet, YMMV. I'm working through an issue with a fairly new 43x (less than 1000 rounds pre-install), where the trigger failed to reset with this installed. It could be an issue specific to me. After two short-range sessions post-install, the trigger failed approximately 10 times in total. I thoroughly cleaned the gun and haven't had an issue in about 400 rounds and still continuing. But the gun wasn't that dirty to begin with. Anyways, I'll keep putting rounds through it and find out more.
