Erma/Glaser Luger .22 Rimfire Conversion

This conversion kit is lot #1713 in the upcoming Rock Island May 2019 auction.

In 1927, a Berlin resident named Richard Kulisch patented a .22 rimfire conversion kit for the Luger pistol. Kulisch’s conversion used a magazine and fired semiautomatically, which made it a much more practical conversion for military and police training than the 4mm single shot conversions than in use. Kulisch appears to have sold the rights to his design to the Erma company – they were an ideal company to market such a thing, having previously sold a .22 rimfire conversion for the Gewehr 98 rifle to the German military. They proceeded to do the same thing with the Luger conversion, which was tested by the military in 1931 and adopted in 1932. It would remain in production until 1940 for the military and police, although it was not really made in large numbers.

In addition to this military contract, Erma made a version for the Swiss commercial market, which was sold by a Zurich gunsmith named W. Glaser. The kit turned the Luger into a simple blowback pistol, and is quite a clever design. In the 1950s, Erma would begin production again for the American commercial market, with a few changes. These were sold by Interarmco, and packaged in a distinctive green box.

  1. NiTi could make the Pederson rifle more pratical; this bit does as per, then “Magic” all kinds of good stuff.

          • Explanation of emotional sound effects: gun cycles when fired, without manual operation input from user. “Manual operation” as in user pulling slide/breech-bolt or cocking hammer.

          • Ah, that is self-loading guns. Ok, when we figured that: how “(…)NiTi(…)” would help there?

  2. The company W. Glaser still exists, but has moved:
    W. Glaser Waffen AG
    Röntgenstrasse 32
    8005 Zürich

  3. Speaking of terms, I was shocked that Ian twice referred to the recoil spring(s) as the “main spring”. I have always thought the main spring is the spring that drives the striker/hammer.

    Also, I wonder if this “Glaser” is related to the Glaser Safety Slug ammo that was made until recently.

  4. I have an ERMA .22 conversion unit for the luger pistol. I have installed the unit into one of my shooter luger pistols but have never fired it as such. Would it be safe to shoot using high velocity .22 ammo or should I shoot only standard velocity ammo. Would std. velocity ammo function reliably in the unit. I sure don’t want to damage any part of the unit. The unit is in a wooden box with a Nazi eagle stamped on the box lid. What would be an approx. value of the entire unit ?
