Beretta does own Benelli. They both share the same corporate address, and it is located in Accokeek, Maryland. I had this question about 5 years ago, so I looked them both up in Maryland's State Department of Assessments and Taxation.

Beretta also owns Burris optics. I bought a lot of Burris Optics and will continue to do so, especially since they will continue to be made in USA. Beretta even makes some shotguns in the US now (i.e., the 3901 line). However, if I cannot get something that is made in the US, and I have a choice of made in Italy or made in Japan, China, Korea, etc, I will pick Italy 11 times out of 10.
