I got to play with one of those yesterday. Neat guns! It might not look exactly right, but it seems well put together and that lock is fast and sure fire every time. We shot it with bare round balls and my homemade powder, and I was quite surprised at the accuracy. A person 100 yards away would be in great danger from that. The balls we had were too big for a patch, so we used them bare. The tumbler isn't right and it would catch on half cock if you didn't pull the trigger through hard, that needs attention but otherwise I could see owning one of those. Great fun!
