Humpty, it has been posted before, here and elsewhere, that the IZ18 is based on the Iver Johnson single. I had one of those, it is nothing like the IZ18. It had an ambidextrous opening lever and central hammer. Unless there is another I.Johnson type, then the IZ18 is not related.

There were also posts accusing the IZ18 of slam fires, ie firing when the gun is snapped close. Obviously those posting did not knnow of the IZ18 automatic hammer block.

But to go beyond the details. Consciously and deliberately hunting with a single can be liberating. The absolute focus on the one and only shot changes hunting for the better, in my opinion. Just look at Pato's expression in the pics. He knows!
