Did Double Gun Journal ever run a series of articles on LC Smith guns?
I wouldn't say there was a "series" on L.C. Smith Guns, but there have certainly been many great L.C. Smith articles over the years by such great authors and photographers as Bill Headrick, Tom Archer, Drew Hause, James Stubbendieck, Colin McLagan, James T. Tyson, and I'm sure many others I couldn't think of.
Most are listed here
