Default M&P Gen 1 dead trigger

First disclaimer, already working with APEX customer service.

Gun. M&P Gen1 9mm.
Installed: Apex forward set sear w/spring
Apex flat faced trigger
Stock trigger return spring
Stock striker assembly
Apex ultimate striker block
Apex semi-drop in barrel
M&P CORE Ported Slide Kit
Leupold Delta Point Pro optic
13 lb recoil spring, tungsten guide rod

Problem
At some point a round will chamber but trigger will be dead. Very random. Have adjusted the trigger loop from initial sizing of .009 to .012 to .015 to approximately .018. per the Apex instructions to allow more over travel. Gun works perfect in dry fire. In the process of replacing the sear housing block and the sear spring. Not sure that will fix the issue. It so random, that I shot practice last Saturday, approx 250 rounds, with no issue. Shot USPSA match on Sun, dead trigger 3 times during the match. Can not replicate the issue. It just "happens". Local gunsmith's only advice to go back to stock. As a comp shooter, that is not an option.

Gun did not have this issue with the standard Apex kit, trigger, sear, striker block. Only happened with the forward set kit, and only after about 1000 rounds.

Any thoughts would be helpful

Check the sear for abnormal wear.
