This guide details the field stripping and reassembly process for the Bergmann Bayard M1910/21 pistol. Key steps involve removing the firing pin, rear sight (main spring retainer), bolt, slide, and locking piece. Reassembly requires careful compression of the main spring and proper alignment of components, with the firing pin acting as a crucial guide.

Quick Summary

The Bergmann Bayard M1910/21, adopted by the Danish Army, featured a wider grip for comfort and an improved extractor for reliability. A key manufacturing change was a threaded barrel, simplifying production compared to earlier integral designs. Its mechanics involve a locking piece that cams to secure the bolt during firing and unlock it during recoil.

Frequently Asked Questions

What were the key improvements made to the Bergmann Bayard M1910/21 compared to earlier models?

The M1910/21 featured a wider grip for improved shooting comfort and an enhanced extractor designed for increased strength and reliability. These modifications aimed to refine the user experience and operational dependability of the pistol.

How did the manufacturing of the barrel differ between Belgian and Danish Bergmann Bayard pistols?

Belgian-made M1910 models had an integral barrel and slide assembly. The Danish M1910/21 variant introduced a significant change by making the barrel a separate component that threads into the slide, simplifying manufacturing processes.

What is the function of the locking piece in the Bergmann Bayard M1910/21's operation?

The locking piece is crucial for the firearm's cycling. When the slide is forward, the locking piece cams upwards to lock the bolt into the slide. During recoil, it cams downwards slightly, unlocking the bolt to allow it to travel rearward.

What makes reassembling the main spring on the Bergmann Bayard M1910/21 challenging?

Reassembly is tricky because the main spring lacks a guide when being compressed to insert the rear sight (retainer). This can cause the spring to kink, making it difficult to manage and requiring significant force and careful manipulation.
