.32 Double Actions are neat little guns, as are the Safety Hammerless ones. You can get current .32 S&W ammo (not .32 long) and use it as it is very mild. You will be amazed by the accuracy of it.
The DA is a 5th Model, and the Safety Hammerless is a 3rd Model.
Then there are the .32 Single Actions. They are both Mod. 1 1/2 (CF) 2nd Issue, the Blue one has the Red Mottled stocks which were only put on Blued guns.
