One of my favorite authors is Ross MacDonald (the pen name for Kenneth Millar). In particular, I have long enjoyed his series of mystery novels featuring private detective Lew Archer as the protagonist. The novels are typically set in the Los Angeles area, where I live. Paul Newman played the character in two films, "Harper" and "The Drowning Pool." In these movies, the name Archer was changed to Harper.
In the novels, when armed, Archer typically packed a revolver...the make wasn't specified, and it was never described much beyond ".38"...but it might well have been a Smith, so I figured it would be a good screen name for a Smith and Wesson forum.
While I'm on the subject, my avatar is a photograph of MacDonald.
