The .357 Magnum comes into its own in this improved, stainless self-loader. By Jan Libourel

In the Coonan Arms stainless steel auto pistol, the .357 Magnum cartridge develops velocities far higher than those obtainable from revolver of similar size, giving it terrific smashing power!

The author fired the Coonan for accuracy and functioning with 10 different .357 loads.  The Coonan handled bullet weights from 110 to 180 grains with equal aplomb.  Properly lubricated, it proved very reliable.
