I've used one of the Navy Arms Ubertis for years - beautifully made, accurate, if you stage the barrel/firing pin so that top left is the first round, and reliable.
I even had Jim Downing engrave it after the Italian proof marks were removed.
I own originals as well, but you need to remember that these were made of essentially wrought iron, so .22CB Caps are about the extent of what can be shot.
