Frequently Asked Questions

What distinguishes the Iver Johnson Safety Hammerless Second Model from other variants?

The Second Model is primarily identified by its two-sided barrel opening lever and the inclusion of a trigger safety bar mechanism, a feature omitted in the later Third Model which was also proofed for smokeless powder.

What type of ammunition is safe to use in the Iver Johnson Safety Hammerless Second Model?

The Second Model was designed exclusively for black powder .32 S&W cartridges. Using modern smokeless powder, even light loads, is strongly discouraged due to pressure differences that can cause mechanical issues and damage.

How does the trigger safety on the Iver Johnson Safety Hammerless Second Model work?

This revolver features a trigger safety bar located on the trigger itself. The trigger cannot be pulled unless this center bar is depressed, functioning similarly to safety mechanisms found in modern firearms like Glocks, but implemented over a century earlier.

What is the significance of the hammerless design in the Iver Johnson Safety Hammerless?

The hammerless design means the firearm lacks an external hammer, which is crucial for snag-free pocket carry. This design enhances concealability and prevents the hammer from catching on clothing or holsters.
