Mark III

Stainless steel Ruger Mark III with magazine.

The first lineup is simply known as Mark III. The pistol's barrel is made from steel bar and is threaded into the receiver which is made from steel tube. The barrel is not removable without machining, though. The layout is similar to the Luger P08, although the operating mechanism was originally copied from the Nambu pistol.

  2. The Ruger manual says "NOTE C—Scope mount bases and rings listed will fit all MARK III and 22/45 MARK III pistols. Only the MARK III Target models are drilled and tapped at the factory. The MARK III Standard models must be drilled and tapped by your local gunsmith. (Drilling and tapping instructions available upon request.)" As of March 2011 it appears as though Ruger has started drilling and tapping the Mark III Standard model.
