I've never heard anyone ('till now) claim an English single trigger was reliable...
Any of you guys seen the old Holland single trigger design in use? The one you push forward to get the tighter barrel? Mental masturbation, in it's purest form.
Even in the cold, I prefer a double trigger. I get around it with one of those giant mittens strapped to my front, that I can slip my hand out of as I mount the gun.
What is the reason, exactly, for a single trigger on a gun with two barrels? I have never understood that.
Best,
Ted
