As indicated in my previous post, you will have to remove the barrel/receiver assembly to determine if you Erfurt has a hold-open. The magazine itself does not lock the toggle assembly back. It only actuates the hole-open, and if the hold-open is working properly it will not work with the magazine removed. There is no difference in an Army or Police magazine as far as function.

Also, just because the pistol has a hold-open is no guarantee that it is working properly.
