I have to admit to some fondness for side-by-sides, but Ruger just wasn't a name that would have occurred to me as a company to go to for one.
The author, Mr. Keefe, did put the obligatory reference to Mr. Kerry's famous double-barrel anecdote into the article.
From what I have heard and read, investment casting as done by Ruger really is high quality steel even if it does sound cheap.
