re: comfort level
I have little to add to Dana’s excellent and thorough comment but having reached old age I realize my time is liimited and my ambitions continuing to grow. I fire regularly with no regard whatsoever after pushing the “start” button. In 20 years I have yet to have a problem. I’ve heard of others who have, but I’m feeling secure in this choice for myself.
