Frequently Asked Questions

What type of action does the 1912 Frommer Stop pistol use?

The Frommer Stop pistol utilizes a long recoil action. In this system, the bolt and barrel remain locked together and travel rearward as a unit for a distance before unlocking to complete the firing cycle.

How does the Frommer Stop's firing cycle work?

After firing, the bolt and barrel recoil together. The bolt then stays rearward while the barrel moves forward to clear the spent casing. Ejection occurs as the barrel reaches its forward position, and the bolt then moves forward to chamber a new round.

What is the locking mechanism on the Frommer Stop?

The Frommer Stop features a 3-lug rotating bolt system for locking. This mechanism ensures the action is securely locked during firing before the recoil cycle begins.

Why is high-speed footage important for analyzing the Frommer Stop?

High-speed footage, captured at 700 and 2000 frames per second, is essential for visualizing the complex and rapid mechanical movements of the Frommer Stop's long recoil action, allowing for detailed analysis of its operation.
