To avoid the dreaded "cap in the action" lock up, I shoot my pistols as seen in some turn of the century films. For the first shot, I aim at my target, cock the gun and fire. Then I point the pistol straight up and thumb the hammer back. If a cap falls off, it always falls free of the gun. I then aim and shoot. This is not a new Italian problem but from what I have read, it was common during the cap and ball period. My "technique" is not new, just copied from William S Hart, Tom Mix and Yakama Canuk. That's my take on it. I'm not saying mine is the final word, just a solution I believe was period correct.
