Frequently Asked Questions

Where is the Manurhin MR-73 revolver manufactured today?

The Manurhin MR-73 revolver is manufactured by Chapuis Armes in Saint-Bonnet-le-Château, France. Production moved to Chapuis Armes from Mulhouse in the late 1990s, and the company was later acquired by the Beretta Group.

What are the key stages in manufacturing the MR-73 revolver frame?

MR-73 frame manufacturing begins with raw steel forgings. These are then subjected to multiple CNC machining stages using specialized 'tombstone' fixtures to create the necessary cuts for the lockwork, cylinder, and sights across different models.

How does Chapuis Armes ensure precision in MR-73 cylinders and extractors?

Chapuis Armes machines the cylinder and extractor simultaneously in a 5-axis CNC machine. This ensures a perfect, permanent match between these critical components, contributing to the revolver's reliability and accuracy.

What finishing processes are used for the Manurhin MR-73?

Despite advanced CNC machining, significant hand-fitting is required. Frames are hand-filed and undergo a multi-hour, two-stage polishing process to achieve the signature Manurhin mirror finish before final bluing.
