If you prefer, you could mill down the "SABATTI" name on the bottom and replace it with "RIGBY". That may make you feel better!

All kidding aside, even if regulation isn't spot-on, this is a lot of gun (and fun) for the money.
IMO, this could be a similar situation to the old days when the Italians started making Sharps, Remingtons, Colts etc. Many buyers were dubious of their quality then, and some were rather crappy, but some makers such as Pedersoli have continued to put out great products at very realistic prices.
Lets hope the Sabatti starts such a trend in the world of double rifles.
