Frequently Asked Questions

What is the unique operating system of the Reifgraber Automatic Pistol?

The Reifgraber Automatic Pistol employs a short recoil system that is augmented by a gas assist mechanism. This system uses two gas ports located at the muzzle to vent gas forward, helping to cycle the heavy action, particularly in the .38 caliber variant.

How does the gas assist feature work on the Reifgraber Automatic Pistol?

The gas assist feature on the Reifgraber Automatic Pistol involves two small ports near the muzzle. When fired, gas is vented through these ports into the front of the frame, providing a pneumatic push that aids the mechanical recoil in cycling the bolt and completing the firing cycle.

What are the key differences between the .32 and .38 caliber Reifgraber Automatic Pistols?

The .38 caliber Reifgraber Automatic Pistol is significantly larger and heavier than its .32 caliber counterpart. Additionally, the .38 version utilizes dual concentric recoil springs for increased power, while the .32 version uses a single spring.

Who designed the Reifgraber Automatic Pistol and when was it patented?

The Reifgraber Automatic Pistol was designed by Joseph Joachim Reifgraber, an Austrian immigrant to the United States. The design was patented on October 30, 1906.
