could be, if I read the new German firearms regulations correctly, their magazines need to be pinned to 10 or 15 rd capacity
the little hole is just that, similar to the sten 20rd desert magazines, converted from wartime 30rd
not a great price, but better than the $ 600 plus mags on GB, that's a bloody crime, everything he has for sale can be obtained on the open market, which he resells at a large profit to the un=educated. I picked up a really nice mag a few weeks back for $ 225. I also got a really nice MP-44 op rod for half of what is advertised on GB
