Rooster & Pete,
I had thought of it years ago and tried to solder in the notch in my '61 Navy but couldn't get it to stick so I gave up. Then last year I thought, "Hey, I use JB Weld for so many other things maybe that would work". So I tried it, tested it, wrote up an article on it and sent it to the SASS Cowboy Chronicle. But before claiming credit I did a search and it turns out that a fellow named Noz (Nozzle Rag) had suggested it to Fingers McGee who suggested it on the SASS Wire last year or so. So Noz was first to suggest it to anyone and Fingers passed it on but I still wrote it up (crediting them too) so others might get more reliability out of their perCUSSIN' revolvers. I suggested (emailed) to Alchemista that he provide hammers without the notch on the Piettas he makes but he stated that his insurance carrier would not allow it. I suggested he at least NARROW the width and put notchless hammers on their Colts without the safety pins on the cylinders to begin with. I did not hear back on that one.
