I recently sold my Glock 19 gen 5 and bought a Springfield Echelon 4.0c. My 19 was 100% reliable as my G43 and my Wife's G42, but neither of us could stand the grip/finger trigger placement on the 19. It isn't uncommon as I found out. My finger comes up so low on the trigger that it rubs against the guard. That and the stiff, slim blade safety will make for a sore finger. Of course it varies from person to person. The Echelon is a treat as far as ergos and trigger go.
