RUGER MARK III
Sturm Ruger was founded in 1949 in a small Connecticut machine shop by William Ruger and Alexander Sturm. Since then, it has become one of the major arms manufacturers in the country.
The Ruger Mark III is a full size, 22 caliber, semi-automatic pistol. The magazine holds ten rounds, and with one inserted in the chamber, the shooter has eleven rounds available.
In The Templar Concordat, this is the gun used by the hitman in Rome. It can be fitted with a silencer, makes much less noise that larger calibers, and at close range a shot to the head is almost always fatal.
