I read online that the Benelli M2 charging handle will work in the Stoeger M3500 and since I was ordering an extension tube for my Stoeger 3500 from S&J Hardware anyways, I ordered one of their M2 charging handles at the same time.
The work required was really basic and was centered around the end that goes in. It needed a bevel added to the inside bit so that it was slightly easier to extract, the shaft had to be turned down just a touch so it didn’t bind on the bolt, and it needed to be shortened so that it didn’t poke out the other side of the bolt. Very easy stuff.
