I have one of those horse pistols myself. It's been languishing in a drawer for the last couple of years (since it's arrival), because I've drifted away from shooting much. I've got grandkids starting to request range time now, so I'm getting anxious to get it out and give it a try. Is that a live round you're firing in the picture? And if so, how was the experience (recoil, accuracy, etc)? I've dry fired mine a couple of times, and I think I've got to take some off the mainspring, or it's really going to eat flints.
