Frequently Asked Questions

What are the key mechanical features of the Swiss Revolver of 1878?

The Swiss Revolver of 1878 features an automatically rebounding hammer, a unique cylinder indexing system for safe loading and firing, and a manual ejector rod. Its action is remarkably simple, powered by only three springs, making it mechanically elegant and reliable.

Why was the Swiss Revolver of 1878 designed without an auto-ejector?

Despite early considerations, the Swiss military opted against an auto-ejector due to concerns about complexity, reliability, and the potential for ejecting live rounds. The manual ejector rod was deemed a more robust and controllable solution for military service.

What caliber does the Swiss Revolver of 1878 use, and why was it chosen?

The Swiss Revolver of 1878 uses the 10.4 Swiss Ordnance cartridge. This caliber was chosen to align with existing Swiss rifle ammunition, allowing for shared manufacturing machinery and logistical benefits, though early rimfire versions presented some case bulging issues.

How does the cylinder retention system work on the Swiss Revolver of 1878?

The cylinder is retained by a unique system where the trigger's lug engages with detent positions on the cylinder band. This provides secure alignment for firing and specific positions for loading/unloading, preventing accidental discharge and ensuring safe handling.
