Iver Johnson Top Break
Model: Iver Johnson Top BreakThe vague model name above refers to the several different top break revolvers manufactured by the Iver Johnson company from 1894 to 1941. The Iver Johnson is one of the few modern examples of the top break ejection system, which has almost completely be replaced by swing-out cylinders.
All Iver Johnson revolvers had a transfer bar safety system, meant to ensure that pulling the trigger would be the only way for the weapon to fire. A number of hammerless double action only models were made as well; all Iver Johnson models automatically ejected the cartridges when broken open, allowing for a swift reload. They were fairly popular pocket pistols, with a .32 Safety Automatic being used to kill President William McKinley.

Where to find
Iver Johnson revolvers have been discontinued for quite some time, but they can be found for very low prices, along the lines of $150-200. Obviously almost all will be used.
Complexity
As a revolver, the design is inherently less complex and less prone to malfunctions than a semi-automatic. Be careful, as the design has been discontinued for well over 60 years; many revolvers are going to be in rather poor condition. Make sure to check if your revolver is safe to use smokeless powder in.
