Frequently Asked Questions

What is the Erma/Glaser Luger .22 Rimfire conversion kit?

The Erma/Glaser kit converts a Luger pistol from its original toggle-lock system to a simple blowback action, allowing it to fire less expensive .22 Rimfire ammunition for practice. It was patented in 1927 and produced by Erma, with a commercial version marketed by W. Glaser of Zurich.

How does the Erma/Glaser .22 conversion kit change the Luger's operation?

The kit replaces the Luger's complex toggle-locked short recoil mechanism with a simpler blowback system. While the toggle still moves, it is no longer locked, enabling the less powerful .22 rimfire cartridge to cycle the action.

What ammunition is recommended for the commercial Erma/Glaser Luger .22 conversion kit?

The commercial version of the Erma/Glaser .22 Rimfire conversion kit specifically required .22 Extra Long ammunition for proper function. This was to ensure sufficient energy for the blowback action to cycle reliably.

When was the Erma/Glaser .22 Luger conversion kit adopted by the German military?

The German military tested the .22 LR conversion kit in 1931 and officially adopted it in 1932. This provided a semi-automatic, magazine-fed training option, a significant advancement over their previous single-shot 4mm training kits.
