A friend had a 1x trigger C&H and it worked well. There were a few skeptics when he got it but the gun proved them wrong.
I had two Westley Richards 1x triggers and they worked flawlessly.
I have a Harrod's 1x trigger gun for over 10 years and there has never been a miss-fire. And, the trigger is selectable---push it forward and it fires the left barrel first---really neat.
